Can I Leave My Humidifier On All Night?

Written by Kevin on March 5, 2026. Posted in air quality.

Humidifiers do a great job at balancing indoor humidity. When indoor levels drop below a certain point, the humidifier turns on to add moisture back into the air. Using the system at night is an excellent way to soothe dry sinuses, prevent itchy skin, and ensure a more restful sleep. However, not all humidifiers operate the same way, especially when it comes to portable versions vs. whole-home setups. This guide walks you through operational tips for both.

Why Do People Use Humidifiers at Night?

The amount of moisture in the air has a direct impact on how well you sleep. When it’s too dry in your home, this increases the risk of waking up with a scratchy throat and stuffy nose. Using a humidifier to increase moisture helps your respiratory health as well. It hydrates the air so your nasal passages and airways don’t dry out and become irritated. Plus, your bedroom will feel naturally cozier. Higher levels of humidity can increase the feeling of warmth. Using a humidifier at night during winter may help you use your heating equipment less, lowering your monthly expenses. Conditions in the summer are usually more humid. You may not need your humidifier as much at night.

How Do Portable Humidifiers Work?

Portable humidifiers are available in many different models and styles. Most versions have a standard tank that you must keep full of water. The tank has a wick or heating element connected to it. This component is responsible for converting the water into a fine mist. Some units have a vibrating ultrasonic plate that breaks the water into tiny droplets to create a cool vapor. No matter the type you use, you’ll have to deal with frequent refills and regular cleaning to prevent mineral buildup. You’ll also have to deal with moving the unit from one room to another. Portable models only cover a small amount of square feet at one time.

How Do Whole-Home Humidifiers Work?

Whole-home humidifiers are very different from portable versions. Instead of moving the unit around your home, the system connects to your HVAC system. When humidity levels drop below a certain setting, this activates the humidifier to introduce water vapor into the ductwork. The conditioned air moving through the ducts then captures this moisture as it flows into each room. Rather than refilling empty tanks every few days, the humidifier connects to your main water line, allowing for automatic refilling.

Is It Okay to Run the Humidifier All Night?

It’s perfectly acceptable to let your humidifier run all night. This includes portable versions and whole-home models. Doing so ensures the air doesn’t become too dry as you sleep. Many people find that a humidifier is the key to creating sleeping spaces that are comfortable and beneficial for one’s health. You may even notice less tossing and turning and fewer static shocks while you’re in bed.

It’s safe to use a humidifier all night because this type of equipment comes with a built-in humidistat. If it detects excessive humidity levels, it will shut itself off to prevent adding too much moisture to the air.

Ways to Make Sure Your Humidifier Runs Safely All Night

No matter the type of humidifier you use, it will need regular care to operate reliably. You can use the following maintenance tips to help your unit last longer and perform better.

Use Manufacturer Recommended Settings

There is an ideal operating range for every type of humidifier. You can find this range by checking the owner’s manual. Following these guidelines is crucial to preventing excess wear on the equipment and making sure it doesn’t decrease humidity instead of increasing it.

Clean Water Reservoir Frequently

Portable units benefit from regular water reservoir cleaning. Ideally, this should occur once every few days. This process helps prevent biofilm buildup and mineral deposits. It also keeps the water source fresh so that the mist is clean and safe to breathe. Whole-home units typically need professional cleaning once per year.

Replace Filters as Needed

If your portable humidifier unit has wicking filters or water panels, you must replace them as soon as you notice signs of scale buildup or discoloration. These signs tend to vary from one home to the next since water hardness levels differ. On whole-home humidifiers, you should change the filter every one to three months.

Keep Unit on a Level Surface

Portable and whole-home versions need a flat, stable surface to set on. This prevents accidental tripping and reduces the risk of internal leaks. Furthermore, it ensures the internal sensors properly read water levels.

Use Distilled Water When Possible

With portable units, it’s smart to use distilled water rather than tap water. The distilled water helps avoid mineral deposits in the tank, making it easier to keep clean.

Inspect Power Cord for Damage

If you notice any damage to the electrical cord, don’t use the humidifier overnight. Fraying and heat damage may contribute to electrical shorts, which can create fire and other safety risks. Getting the cord repaired or replaced is crucial to preventing hazards.

Avoid Overfilling the Tank

On portable units, the tank will have a “max fill” line. Staying below this line is vital to keeping water from splashing onto the electrical components. We always recommend staying about half an inch below the “max fill” marker each time you refill the tank.

Keep Air Intake Vents Clear

Unlike portable units, whole-home versions need optimal airflow through the ductwork to function correctly. This means all air vents throughout the home should always remain open and clear. Closed vents greatly increase the likelihood of pressure imbalances, reduce efficiency, and lead to uneven humidity levels.

Check Built-In Humidistat Settings

All humidifiers have a humidistat that tells the system when to turn on. This component needs accurate calibration to reflect the actual moisture in the home. If you think your unit isn’t reading correctly, we can recalibrate it for you.

Place Portable Units Strategically

Where you place portable humidifiers greatly influences how well they distribute moisture. You don’t want them too close to the bed because excess mist can cause damp bedding and discomfort. You also don’t want them placed directly on carpet or wood furniture since moisture can cause staining or damage.

Best placement tips for portable humidifiers:

Place on waterproof surface
Keep 3 feet away
Avoid carpeted floor areas
Allow open air circulation
Center the device on a flat surface

Seal Duct Leaks Promptly

The condition of your ductwork influences how well a whole-home humidifier can keep moisture levels balanced. If it has leaks, gaps, or loose connections, the moisture will seep out before it reaches each room. We can fix duct leaks for you using proven repair methods.

Is Indoor Air Quality Testing Worth It?

Written by Kevin on May 5, 2025. Posted in air quality.

At Meades HVAC, many of our customers are increasingly concerned about indoor air quality (IAQ). Many want to know how they can tell whether their home’s indoor air quality is good, especially if they have allergy sufferers at home. They frequently wonder if indoor air quality testing is necessary and what it can actually find. Here is a look at what you should know about IAQ, how you might notice problems, where testing fits into the picture and what the options are for addressing the situation.

Causes of Poor Indoor Air Quality

The foremost issue in IAQ is particulate matter. This is the stuff that you often see either directly or indirectly as accumulations on surfaces. Dust and lint are the biggest bits of matter floating in your home’s air. You expect your HVAC’s base filters to do most of the work involved in capturing big pieces of lint, but dust will often get through simple fiberglass filters that you see on standard furnaces. Pet dander and hair can do the same.

There are smaller particles in the air, too. Pollen from outdoors can get into your home, especially during the spring. Some enters through HVAC air intakes, and more also comes in through windows and doors when those are open. Mold can develop in homes due to high humidity levels, and it also circulates as the HVAC system blows air. Even bacteria and viruses circulate in your home. Finer filtration systems, especially high-efficiency particulate air (HEPA) filters, are usually best for resolving these problems.

One of the less discussed IAQ issues is chemicals. Volatile organics chemicals (VOCs) off-gas from many types of household products and materials. Paints, carpets, upholstered furniture and treated lumber all can emit VOCs. Cooking can generate VOCs, particularly through gas burners and types of anti-stick coatings. Even air fresheners can off-gas VOCs. Dealing with VOCs typically involves more aggressive solutions than filtration.

Another less-discussed issue is carbon dioxide (CO2). This is a byproduct of breathing by every person in your home, and it can accumulate quickly. High concentrations of CO2 can affect cognitive function and make you feel fatigued. Typically, improved ventilation is necessary to address high CO2 levels.

There are plenty of other possible sources of poor indoor air quality. Outdoor pollution from vehicles and factories can infiltrate your home. Nitrogen dioxide and carbon monoxide (CO) result from the combustion in your home that heating and cooking cause. Fortunately, there are ways to detect all these issues and then address them.

Identifying Potential IAQ Problems

Household health is often the first thing that worsens when indoor air quality is poor. You might notice that you seem to constantly have dry eyes or skin. Many people experience sore throats or recurring colds, too. Folks who suffer from allergies, asthma and COPD may have more attacks. Particularly if you notice that the symptoms go away when you get outside, go to work or visit someone else’s place, then you should suspect that your home’s IAQ isn’t great.

HVAC performance also can suffer from poor IAQ. Dust, pet dander, hair and other matter can clog system filters. If your home has high humidity levels, your heating and cooling systems may spend more energy because moist air has greater thermal mass than dry air. Particulate matter can also make it harder for systems to take in fresh air, making them more inefficient. Over time, debris can even get into fans and blower motors to slow their performance.

Inefficient operation frequently encourages component failures, shortening HVAC lifespans. If you’re having a lot of trouble keeping your HVAC running well, you need to check whether IAQ is the culprit.

Dust accumulation is a simpler clue. In addition to fine dirt, dander and other matter, dust can accumulate due to mold growth. The dust blows around during each HVAC cycle and settles on surfaces when the cycle ends. Dust is more likely to accumulate in spots with less ventilation or unbalanced airflow, so you may notice it only in specific rooms.

The sniff test is another way to find IAQ problems. If parts of your house smell musty, mold may be growing. Stale air often indicates poor airflow.

Indoor Air Quality Testing

Multiple air quality tests are often necessary, but there is almost always a way to test for every potential IAQ problem in a house. Multi-gas analysis is available to check for CO2, carbon monoxide, nitrogen dioxide and most VOCs. Modern HVAC sensors can also determine the current humidity level in your house with a high level of precision. Mold and microbial testing usually involve taking lab samples.

Notably, CO2 testing serves as an excellent proxy for many other IAQ problems. Generally, indoor air levels of CO2 should be below 800 parts per million (ppm). However, many modern homes have been aggressively insulated and sealed, and this leads to levels that can easily exceed 2,000 ppm when a house is closed up in the winter. If the CO2 ppm level in a house is high, there is a chance that other undesirable IAQ levels are high, too.

Our technicians also directly test HVAC performance to make sure it meets expectations. We will meter the airflow from your home’s vents and air returns. We can perform pressure differential testing to verify that your HVAC and ventilation systems are moving enough air. Likewise, we can check ducts and filters for particulate accumulation.

IAQ Solutions

An HVAC system makes it easy to centralize multiple IAQ solutions. Your options will depend on the specific problem. For example, we recommend humidifiers for households that have trouble with dry skin, especially in the winter. Likewise, a dehumidifier might be necessary to discourage mold growth. Many homes use both kinds of systems to keep humidity in the optimal range between 30% and 50%.

HEPA filters are often useful, especially when integrated with a larger air purification set. We often configure an IAQ package that operates at the back end of your heating and cooling systems. Air goes into your home’s return registers and then passes through high-grade filters before returning to the HVAC system as clean air to breathe. Some whole-home air filtration systems use HEPA-level filter media, but they aren’t compatible with all HVAC systems.

We may recommend a more aggressive solution like a UV light purifier, too. If you’ve had a lot of trouble with microbes or certain chemicals, consider a system that emits UV-C light to treat the air and break them down. This system usually integrates with air purification packages in the air return.

Ventilation improvements also make a difference. Encouraging air exchange with the outdoors reduces the accumulation of indoor irritants. Modern heat exchangers in high-efficiency HVAC systems also make it possible to recover much of the heat from the air before expelling it on cold days.

Signs of Poor Indoor Air Quality at Home

Written by Kevin on March 1, 2025. Posted in air quality.

Poor air quality can affect you anywhere, from the outdoors to the inside of your workplace. If you feel unwell when you’re inside your home, there may be contaminants in your indoor air that are causing your symptoms. Knowing the signs of poor indoor air quality can help you make appropriate changes that will reduce these contaminants. After all, your home should be a safe haven from the pollution and particulates that are outside. Here are some symptoms of poor indoor air quality and ways to combat them by keeping your HVAC system maintained and incorporating add-ons and standalone devices that help fight against poor indoor air.

Common Indoor Air Quality Issues

The types of particulate matter in a home can vary depending on factors such as whether you have pets, how frequently you run your HVAC system, the type of air filter you use, relative humidity levels, and the level of ventilation in your home. Common contaminants include pollen, pet dander, mold spores, dust, dust mites, and volatile organic compounds (VOCs). VOCs are chemicals found in cleaning products, building materials, air fresheners, and many other sources.

Exhausting the air inside your home to the outdoors is ideal, but many homeowners keep their doors and windows closed to help retain conditioned air. This is also an effective way to keep pests outside where they belong. During allergy season, it’s beneficial to keep your windows and doors closed during times of the day when pollen levels are extremely high.

If your home has a high relative humidity level, mold spores may be prevalent in the air. Mold can cause allergies, asthma, and respiratory symptoms like shortness of breath. It’s ideal to keep your indoor relative humidity between 35% and 50%.

Symptoms of Poor Indoor Air Quality

Poor indoor air quality can affect your body in several ways. For people who are prone to allergies, particulate matter can cause itchy eyes, sneezing, coughing, and a runny nose. During the spring months, it can be difficult to discern between outdoor and indoor allergies. Other symptoms that can result from poor indoor air quality (IAQ) include headaches, nausea, extreme fatigue, brain fog, and even gastrointestinal upset. If your symptoms seem to worsen when you’re at home, the problem probably lies within your residence and not outdoors.

Pay attention to your skin’s health. Dry air can lead to dry and irritated skin and sinuses. If you encounter a high prevalence of allergens in your air every day, you may frequently experience hives and other rashes.

Issues With Your HVAC System

Good indoor air quality is necessary for your health and can also help protect the integrity of your HVAC system. If particulate matter accumulates on the interior components of your heating and cooling equipment, it can cause these units to work harder to meet your indoor comfort needs. Over time, these components can experience wear and tear, eventually breaking down.

If you need frequent repairs, your indoor air quality (IAQ) may be the issue. You may also have an IAQ problem if you find yourself replacing your heating and cooling equipment more often than usual. Furnaces and air conditioners usually last approximately 15 to 20 years, which reflects the use of routine maintenance to catch minor issues and fix them early on.

Your air filter should last approximately 30 to 90 days, depending on the type of filter you’re using. Additionally, the amount of time you run your HVAC system will impact filter longevity. If your filter seems to be getting clogged quickly, you may have a high prevalence of particulate matter in your indoor air.

Leaving a clogged filter in your furnace can strain your equipment and decrease airflow through your system. The more clogged your filter becomes, the worse your indoor air quality will become. Eventually, particulates will pass into your ductwork and out through the vents in your living spaces.

Improving the Quality of Your Indoor Air

Some very effective methods can improve indoor air quality. First, make sure you regularly change your furnace filter according to the manufacturer’s instructions. Second, use a filter that provides adequate filtration. The Minimum Efficiency Reporting Value (MERV) reflects the effectiveness of a filter.

The higher the MERV rating on a filter, the more particulate matter it will be able to remove from the air. Just don’t go over a MERV rating of 12 if you have a standard furnace. Anything over that rating will cause too much airflow restriction and can lead to equipment strain, hot and cold spots in your home, and a spike in energy consumption.

Consider installing a whole-house air filtration system on your HVAC system. This equipment will include another layer of filtration that can remove as much as 99.97% of the particulate matter in your indoor air. It can usually handle more airflow restrictions than your furnace, allowing you to use higher-quality filters.

If the relative humidity in your home rises above the recommended 50%, this can promote the growth of mold. Additionally, more particulate matter can be held in humid air. You can control the humidity in your home using a whole-house dehumidifier for high levels of moisture. A whole-house humidifier can add moisture back into dry air.

Whole-home equipment is much more effective than portable models that only address a small amount of square footage at one time. Also, you can protect the interior components of your heating and cooling equipment while also safeguarding the integrity of your ductwork. Fluctuating humidity levels can lead to structural damage and harm to items like flooring. Dry air can cause wood to contract, while high humidity can lead to wood expanding. These fluctuations can cause warping and permanent damage.

If you and your family experience poor indoor air quality (IAQ), you may get sick frequently, experiencing a variety of nasal symptoms, congestion, and other illnesses. If you are concerned about mold and other microbes in your air, a UV light is a great upgrade to consider. Specifically, a UV-C light installed in your HVAC system will damage the DNA of any bacteria, viruses, or pathogens present in your air.

This will help keep you and your family healthy and safe all year. To avoid radiation exposure, these lights should be installed by professionals. Ongoing maintenance includes cleaning the surface of the light and replacing it yearly to ensure its effectiveness.

Meades HVAC is available to help you with all your indoor air quality needs. An assessment of your indoor air quality can help determine what kind of contaminants you’re dealing with. We can also provide duct sealing to further improve the quality of your indoor air. Our company can install humidifiers, dehumidifiers, whole-home air filtration, UV air sanitization, and air filters. And our technicians can also install, maintain, and repair heating and cooling equipment.

Signs Your Indoor Air Quality Is Poor

Written by Kevin on December 6, 2024. Posted in air quality.

The indoor air in your home is one of the most important aspects of your health. Though it may seem clean, the air in your home can be full of hidden pollutants that negatively affect your health and comfort. Indoor air quality may be linked to everything from minor irritations like itchy eyes and headaches to respiratory conditions and chronic fatigue. The first step toward a better home environment is learning the signs of poor air quality.

Frequent Allergy Symptoms

Poor indoor air quality can manifest in frequent allergy symptoms such as sneezing, coughing, itchy eyes, and runny noses. Allergens, including dust mites, pet dander, mold spores, and pollen, become airborne contaminants, especially in homes that are not well-ventilated or lack proper filtration systems. Such allergens persist and build up inside. Other sources of irritants inside of your home may include volatile organic compounds from cleaning products and fine particulate matter mostly referred to as PM2.5. Symptoms from these contaminants could continue to manifest throughout the year and possibly during certain seasons.

Respiratory Problems

Of all the possible medical issues people can suffer due to bad indoor air quality, respiratory problems are probably the most frequent. Dust, pet dander, mold spores, and chemical fumes may collect within poorly ventilated parts of your home and will then serve as irritants to the respiratory system. This may eventually provoke symptoms such as chronic coughing, wheezing, and shortness of breath after long-term exposure.

The symptoms are usually worse for people with pre-existing conditions such as asthma or COPD, meaning they can develop attacks with increasing frequency and intensity. Even a healthy person can suffer from long-term exposure, which may result in bronchitis or chronic throat irritation. Poor indoor air quality may even cause, in some cases, new respiratory problems whereby the continuous inhalation of airborne irritants over a long period weakens lung function.

Persistent Odors

Another sign of bad indoor air quality in your home can be lingering odors. Most of these smells can result from a built-up amount of air contaminants that cannot be removed because of poor ventilation or no filtration. Common culprits include volatile organic compounds given off by household products such as cleaning supplies, paints, and furniture. To add to the unpleasantness, smells from cooking, pets, and even cigarette smoke may also linger.

These odors can become more concentrated inside a property when indoor air quality is compromised and thus may be hard to ignore. Other than occasional odors that soon fade, persistent odors signal that the pollutants are being caught and circulating constantly in the air. You might begin noticing irritation in your senses and discomfort or even mild health symptoms over time, such as headaches or nausea.

Excessive Dust

Excessive dust in the house is a sure sign of poor air quality. Dust consists of small particles of dead skin cells, fibers of fabrics, and microscopic debris, which are all pushed into the air and circulated throughout your living spaces. If there is bad air quality in your home, you can check a few surfaces that aren’t frequently dusted to confirm. Or, you can dust and then track how long it takes before another layer of dust settles on them. If this happens quickly, then you should have the air quality checked.

Dry or Irritated Skin

Dry or irritated skin is a symptom of poor IAQ. When the air in your home becomes imbalanced, your skin can lose its natural ability to maintain hydration. This generally happens when there is inadequate ventilation that allows particles such as dust and other small debris to stay in the air and settle on your skin. These particles act like a barrier to the skin to retain its moisture. This then leads to dryness, flakiness, and irritation.

Other Illnesses

Indoor air quality plays an important role in our daily health. Compromised conditions in your home can be manifested through physical discomfort and recurring health problems. One of the most telling signs of poor air conditions is constant fatigue. If you feel consistently tired or sluggish without other possible reasons, the air you breathe could be the issue.

Frequent headaches are another clear indicator that something is amiss. These are not your typical stress-related headaches but rather a result of inhaling air that contains irritants. Poor indoor air puts additional strain on your health, often leading to persistent head pain that worsens with prolonged exposure.

Unexplained HVAC Odors

Strange smells emanating from the HVAC system in your home generally indicate poor indoor air quality, if it isn’t a mechanical failure. Such odors mean your system is only recirculating polluted air, and this affects what you breathe, confirming that your interior environment is not healthy.

Frequent Static Shocks

If you’ve been getting a lot of static shocks lately, it may be a sign of bad IAQ. When ventilation is poor, the humidity inside tends to decrease. When the humidity is low, static electricity accumulates pretty quickly. Such an imbalance does not just cause discomfort but also shows that the air is not as regulated as it needs to be. While static shocks are minor inconveniences, they can point to a broader problem of poor air circulation and filtration in your residence, which can affect your comfort and well-being.

Visible Airborne Particles

Seeing small particles suspended in the air is a clear and concerning sign of poor indoor air quality. These particles, often visible in light beams streaming through windows, indicate that the interior of your home is filled with contaminants that aren’t being properly filtered or ventilated. They could include dust, fibers from fabrics, or other microscopic debris. When these particles remain airborne for extended periods, it suggests that your HVAC system or air filtration devices are not effectively removing them. This not only impacts the cleanliness of your home but also serves as a visual reminder that the air you’re breathing may contain harmful pollutants.

How to Combat Poor Indoor Air Quality

There are several ways to combat bad air quality. After you have the IAQ tested in your home, one of our professionals can help you decide on a solution. You may need a humidifier, which can help increase the moisture levels in your home. Alternatively, a dehumidifier helps reduce the humidity inside. There is also UV air sanitation, which helps remove airborne pathogens like bacteria. Changing your HVAC filters on a regular schedule will also help keep the air quality high.

Whole-home air filtration is another way to ensure that the quality of air in your home is as healthy as possible. This type of air filtration can help remove harmful particles like pollen, pet dander, or mold. A whole-home filtration system can also help keep odors limited and reduce some of the triggers for allergies or asthma.

At Meades HVAC in Sterling, VA, we provide humidifiers, dehumidifiers, and whole-home air filtration services for homes in the area. Our friendly team also offers water heater, gas line services, and more. Contact Meades HVAC for more information today!

Could Whole-Home Air Filtration Help With Allergies?

Written by Kevin on August 19, 2024. Posted in air quality.

Allergy symptoms can include headaches, itchy eyes, a scratchy throat, sneezing, and coughing. Outdoor allergens like pollen and pollution can exacerbate these symptoms. Indoor conditions are often worse in Sterling, VA homes due to exposure to dust, dust mites, mold spores, pet dander, and more. If you or someone in your home suffers from allergies or asthma, there are several things you can do to reduce the symptoms. This includes the use of a whole-home air filtration device.

What Is Whole-Home Air Filtration?

The air inside your Sterling home can be affected by several contaminants. Particulate matter enters your sinuses and body, causing irritation if you’re prone to allergy symptoms. In addition to pollen, dust, and mold spores, volatile organic compounds may also be an issue. VOCs come from things like building materials, chemical-based cleaning products, beauty products, air fresheners, scented candles, and much more. VOCs have a negative impact on your health, causing allergy issues and other symptoms like headaches and fatigue.

An air filtration device is equipped with one or more filters that will remove particulate matter from the air that is circulating throughout your home. There are different types of filtration available. Some remove very fine particulate matter that is as small as 0.3 microns in size. In many cases, whole-house filtration can remove almost all the contaminants from the indoor air.

What Options Are Available?

You’re likely familiar with the portable purifiers and filtration devices that you can move from one room to another based on your indoor air quality needs. Whole-house filtration is more convenient and effective. It addresses the indoor air quality on an entire residential structure. All the air that’s coming out of your vents and into your living spaces will be much cleaner and healthier. There’s no need to move a bulky unit around. Maintenance is much simpler as well.

High-efficiency particulate air filtration, or HEPA for short, is effective at removing 99.97% of indoor air pollutants. These filters need to be removed and replaced periodically. HEPA filters can be combined with other forms of purification and filtration.

Activated carbon filters are extremely effective at removing volatile organic compounds and odors from your indoor air. These filters are often combined with HEPA filters or other types of filters.

Electrostatic filtration removes particulate matter from your indoor air by charging particles and trapping them on oppositely charged collection plates. These plates should be removed periodically, cleaned, and replaced. This is a cost-effective whole-house filtration option that is very effective at reducing allergy symptoms.

It’s likely that you’re using some form of media filter in your HVAC system. Whole-house filtration works alongside these standard filters to remove particles from your indoor air. Unfortunately, AC and furnace filters on their own don’t remove enough particulates in most cases, especially if you’re someone who suffers from allergies.

Whole-House Filtration Maintenance

It’s important that you keep up with the routine maintenance of your whole-house filtration system. This ensures that your equipment is effectively removing any contaminants that could conceivably cause you a problem with your allergies. When your equipment is installed, our team will educate you on how often you should be changing the filters in your system. We can also talk to you about the different types of filters that are available and which you should use based on your symptoms and air quality needs.

It’s highly advised to schedule routine maintenance for your both your HVAC system and filtration equipment. During these appointments, our team will look at all the interior components of your setup and clean them. This provides us with an opportunity to catch any problems before they become more involved or serious. If necessary, we can make repairs.

We can also provide you with follow-up indoor air quality testing to ensure that your whole-home filtration system is handling your indoor air quality properly. There may be a need for additional improvements, such as the installation of a whole-house humidifier or dehumidifier.

Other Methods of Improving Indoor Air Quality

In addition to whole-house air filtration, there are other improvements that can be made to your home’s HVAC system to decrease allergies. Humidity is something that can affect allergies. If the air inside your home is too humid, this can increase your exposure risk to mold spores and allergens. A whole-house dehumidifier can bring moisture levels back down to an acceptable level. If your home is too dry, you can add moisture using a whole-house humidifier. Ideally, relative humidity should be kept between 35% and 55% throughout the year in Sterling. Your needs may change depending on the season and the weather. You can utilize both types of equipment in your home, using your thermostat to switch between the two units.

Ventilation is something that is very important for reducing allergy symptoms. If the air inside your home is stale and stagnant, this can increase your exposure to allergenic particulate matter. Removing indoor air and exchanging it with fresh air from the outside can be done in a few different ways. Exhaust fans are commonly installed in homes in the Sterling area. These fans are usually in your bathrooms and kitchen. You should run your exhaust fans while showering to remove moisture from the air. Your kitchen exhaust fan will help to remove cooking odors and fumes. If you feel like ventilation is a concern in your home, there are other types of exhaust fans that can be installed in areas such as your attic. This healthy exchange of air can help reduce your allergy symptoms and improve your indoor air quality.

Routine maintenance for your HVAC system can also improve your indoor air quality. Our team will inspect various parts of your heating and cooling equipment, in addition to any air filtration equipment that you’re using. We will clean interior components to boost efficiency. We can also inspect your ductwork to ensure that particles and pests aren’t entering your circulating air through gaps and cracks. This service should be scheduled once per year. This can also prevent issues from occurring with your HVAC system that could leave you without use of your heating or air conditioning functions, in addition to your air filtration processes. Our professionals can perform an indoor air quality assessment to determine the current state of your indoor air.

Indoor Air Quality Enhancement

Written by Kevin on December 13, 2023. Posted in air quality.

Though it’s not commonly taught, your indoor air quality matters. There are many things you can do to enhance it. In order to improve your home’s environment and breathe easier, consider the following tips.

1. Use Measuring Tools

When it comes to the air in your home, it’s invisible. You can’t see whether the air is dirty. The only way you’ll know is by the physical reaction that you have to the air or by a certain odor. However, even when it comes to odors, there’s a concept called nose blindness. When you’ve experienced nose blindness in your home, you’re immune to any offensive odors that are regularly present in the air. This is why it’s best to invest in measuring tools to help you know when the indoor air is of great quality or not. There are two tools you’ll particularly want to invest in.

For starters, consider purchasing a hygrometer. It is beneficial for measuring the amount of humidity in the air. If you have too much humidity, this can lead to the spread and growth of mold, mold spores and bacteria. If you don’t have enough humidity in the air, this leads to dryness. Dry air can exacerbate issues related to nosebleeds, asthma and other respiratory issues.

In addition to investing in a hygrometer, consider purchasing an indoor air quality monitor. The indoor air quality monitor will definitely tell you about the humidity in the air. However, it takes it a step further and measures carbon dioxide, temperature and volatile organic compounds (VOCs).

2. Keep Tabs on the Moisture Levels

Once you’ve invested in a hygrometer or an indoor air quality monitor, you’ll be able to see whether there’s too much moisture and humidity in your home. If this is the case, you’ll want to invest in a dehumidifier in order to address the issue promptly. Dehumidifiers are particularly helpful in areas like basements, bathrooms, and kitchens. If you don’t spend a lot of time in your basement, it can be easy for humidity to reach dangerous levels without you realizing it. In addition to keeping a monitor in the basement, it’s always wise to make frequent visits to different areas of the home that typically go untouched. This will help you stay on top of issues before they become costly and dangerous.

Another way to control the moisture in your home is to keep an eye out for leaks. If you have cracks and leaks in any area of your home, this can lead to the spread and growth of mold, bacteria and mildew. These bacteria are very dangerous to inhale and live with. This is why it’s best to keep the humidity between 30 and 50%.

3. Cultivate a Green Thumb

Transpiration is the process by which plants release moisture into the air. This natural process not only benefits the plants themselves but can also have positive effects on indoor air quality. Larger spaces may benefit from having more plants to achieve a noticeable effect.

Certain plants are particularly effective at improving indoor air quality. Examples mentioned include peace lilies, spider plants, and aloe plants. These plants are known for their air-purifying properties.

While you don’t need to turn your space into a jungle, it’s suggested to consider adding extra plants, especially if the room’s square footage is over 500 feet. For those who may not have a green thumb, selecting low-maintenance plants is a wise choice. These plants are easier to care for and can still provide air-purifying benefits.

Speaking to a botanist or plant care specialist can be valuable for learning how to properly care for indoor plants. This ensures that the plants remain healthy and continue to contribute to improved air quality.

4. Maintain Proper Ventilation Practices

Start by opening the windows a few times a week, if not daily. Do this for at least 15 minutes at a time. Allowing fresh air to circulate helps maintain indoor air quality and reduces the likelihood of “nose blindness.” If you have seasonal allergies, be mindful of outdoor allergens and adjust the frequency of window openings accordingly.

Invest in a really good air purifier. Choose an air purifier with HEPA filters to actively remove contaminants from the air. When itâ€™s time to cook, turn on the exhaust fan in the kitchen. Especially when using the stovetop, turn the exhaust fan on to eliminate pollutants generated during cooking. Another place to use an exhaust fan is the bathroom. Use the exhaust fan in the bathroom when taking a shower to remove excess moisture and prevent the growth of mildew and mold. Keep bathroom doors open to facilitate air circulation and prevent moisture buildup.

Implementing these practices can significantly contribute to maintaining good indoor air quality, preventing the accumulation of pollutants, and reducing the risk of issues associated with excess moisture. Proper ventilation is essential for creating a healthy and comfortable indoor environment.

5. Prioritize Cleanliness

Maintaining cleanliness is paramount to making sure the indoor air is of great quality. If you’re not the most organized in the cleanliness department, it’s time to create systems that help you keep your home clean on a consistent basis. Start by maintaining a system of taking your shoes off when you enter the home, as shoes touch everything everywhere when you’re outside. With so much exposure to a myriad of bacteria, it’s best to decrease the spread of it by taking your shoes off at the front door. When you have guests over, you can offer socks or slippers in order to help them feel more comfortable about taking their shoes off.

Another way to promote cleanliness at home includes maintaining a system. If you’d like to have a cleaning professional come through and clean your home on a consistent basis, that’s a great start. However, if you simply take the time to vacuum and clean your floors on a consistent basis, this will be a great start. Another habit to include involves prioritizing the removal of dust. Clean all the countertops and spaces where dust and bacteria can collect. If you do this once a day, you’ll be on your way to maintaining a clean home that helps to improve the quality of your indoor air.

6. Maintain Your HVAC System

Your HVAC system is responsible for pumping out the air that goes throughout your home. During the colder months, you’re typically turning on the heat. During the warmer months, you’re typically pumping out cool air to keep your home comfortably cool. As you push out the air, it comes through your air filters. Those air filters need to be changed on a consistent basis. Typically, it’s recommended that you change your air filters once every 90 days. If you have pets or allergies, you’ll want to increase the frequency of your air filter changes. When your air filters become clogged, this makes the HVAC system work harder. As a result, you’ll end up having to pay more for the energy that your system had to put out.

Also, maintenance matters. Connecting with your local HVAC professionals can make a major difference in your indoor air quality because they’ll be able to make sure your HVAC system is working at peak performance. They’ll also be able to catch any repairs that need to be taken care of. If a certain component of the system needs to be cleaned, this can be done by a professional. When they take care of it, they’ll have the eye to see when something’s about to go wrong and how you can be proactive in making sure you stay on top of your maintenance and repairs.

Can a Whole-Home Humidifier Also Dehumidify Your Home?

Written by Kevin on December 16, 2022. Posted in air quality.

Using a whole-home humidifier can make a major difference during the winter by adding moisture to the air so that your home doesn’t feel so dry. Many people in more humid climates also turn to whole-home dehumidifiers during the summer to ensure the humidity level never rises high enough to potentially create water damage and mold issues. If you find that you need both a whole-home humidifier and a dehumidifier, you may be wondering whether there is a unit that can do both, and here is the answer.

Whole-Home vs. Portable Units

You can find many different portable units that can work as both a humidifier and a dehumidifier. These units can definitely help to overcome issues with low or high humidity, but their range is usually limited to only one room. If you wanted to control the humidity level throughout the entire house, you would need to have a separate unit in almost every room or space.

Unfortunately, there aren’t currently any whole-home units that can work as both a humidifier and a dehumidifier. If you find that you need a humidifier in the winter and a dehumidifier in the summer, you will need to purchase separate whole-home units as they simply don’t work the same way.

How Whole-Home Humidifiers Work

A whole-home humidifier is tied directly into your plumbing system and works alongside your heating system to control the moisture level in the home. There are several different types of whole-home humidifiers that each work slightly differently, but most whole-home units are installed inside your ductwork to humidify the hot air that blows out of your vents. Some units produce hot, moist air while others produce cool, moist air, but the effect is the same either way.

Most whole-home humidifiers will typically run whenever your furnace does and then shut off as soon as your heating system shuts down. Still, there may be times when the humidifier doesn’t run at all or shuts off before your furnace if the unit detects that the humidity level is where it should be.

These units can be installed either in the ductwork that brings cold air into the furnace or in the supply plenum where hot air exits the furnace. Both locations will provide the same benefits and work the same way. However, it is always better to install the unit in the return duct before the furnace if possible.

The issue with installing it in the supply plenum is that it usually means that the humidifier will be located directly above or next to the furnace. Should the water line that feeds the humidifier or the unit itself ever develop a leak, the water could seriously damage or ruin your furnace or the blower fan.

There are also large standalone whole-home humidifiers that work independently from your HVAC system. These units have their own fan that circulates the warm, moist air. Some of these units can effectively manage the humidity level in an area of up to 4,000 square feet. However, the fact that this type of unit has no way to fully circulate the moisture throughout the entire building means that they are still less effective than units that work alongside your heating system.

How a Whole-Home Dehumidifier Works

Whole-home dehumidifiers are typically also installed inside your ductwork and work along with your cooling system to remove moisture from the air. Both air conditioners and heat pumps remove quite a bit of moisture from the air on their own due to the heat transfer process that they use. Inside your HVAC air handler is an evaporator coil that uses cold refrigerant from the outdoor cooling unit to remove heat from the air.

The difference in temperature between the hot air and the cold refrigerant causes much of the moisture in the air to condense into water. This water then drips off the coil and flows through the condensate drain system and then either directly out of the building or into a floor drain. In drier climates, the cooling system alone is typically sufficient to keep the building from becoming too humid. However, this isn’t always the case in more humid climates or in situations where your home has lots of air leaks due to it not being well sealed or not sufficiently insulated.

Whole-home humidifiers remove additional moisture from the air in much the same way as your cooling system does. The HVAC blower fan draws in hot air through the return duct system. This air is forced over the evaporator coil, and then a fan in the dehumidifier draws the air into the unit itself. This air is then forced over a cooler in the dehumidifier so that most of the moisture condenses into water. These units are typically connected directly to your cooling system’s condensate system so that the water can easily be drained away.

As with whole-home humidifiers, the dehumidifier will generally run whenever your air conditioning is currently running. However, you can also set the unit to run independently for those days when it is still humid but you don’t need your AC. In this situation, the blower fan on your HVAC system will still need to run to supply air to the dehumidifier.

You can easily find whole-home dehumidifiers that can work in buildings up to 5,000 square feet. Some of these units are capable of removing nearly 12 gallons of water from the air in a single day, which makes them far more effective than an air conditioner or heat pump could ever be on its own.

One of the biggest benefits of a whole-home dehumidifier is that it can help to reduce the strain on your cooling system and lower your energy costs. The more humid the air is, the harder it is for the cooling system to remove heat and the longer the system will have to run to effectively cool the building. By removing additional moisture from the air, a whole-home dehumidifier will help lighten the load on your cooling system and ensure it doesn’t need to run for as long.

How a Humidistat Works

Both whole-home humidifiers and dehumidifiers are controlled by a device known as a humidistat. The humidistat is usually mounted next to your thermostat and works to constantly measure the relative humidity level inside the building. Just like your thermostat measures temperature to signal the HVAC system to turn on and off, the humidistat also signals the humidifier or dehumidifier when to start and stop.

Depending on the specific brand and model of humidifier and dehumidifier you choose, you may need a separate humidistat for each unit. However, some brands make humidistats that can be used to control both types of units. If you have a smart thermostat, you may also be able to use this to control the humidifier and dehumidifier since many of these devices have a humidistat built in.

At Meades HVAC, we install, maintain, and repair a variety of indoor air quality units including humidifiers, dehumidifiers, air filtration systems, and UV sanitizers. We also offer air quality testing so that you can determine what your air quality is and how to overcome any potential issues.

Proven Ways to Enhance Your Home’s Air Quality

Written by Kevin on November 20, 2022. Posted in air quality.

If your home feels stuffy, dusty, or a little stale no matter how often you clean, you are not imagining it. Learning how to improve indoor air quality starts with understanding what is actually happening inside your walls and ductwork, not just what you can see on the surface. In Northern Virginia, where homes stay closed up for long stretches during hot, humid summers and cold winters, dust, allergens, and excess moisture can build up fast. That buildup often shows up as sneezing that eases the moment you step outside, a musty smell that returns no matter how often you clean, or rooms that feel stuffy even with the thermostat set right. The good news is that better air is within reach, without a full home overhaul.

Why Indoor Air Quality Matters in Sterling, Ashburn, and Reston

Many homes across Loudoun and Fairfax counties, especially older properties in established neighborhoods, were not built with today’s tighter insulation and sealed windows in mind. That means the air inside gets recirculated again and again with fewer chances to refresh. According to the U.S. Environmental Protection Agency, indoor air can carry higher concentrations of certain pollutants than the air outside, largely because dust, pet dander, and moisture have nowhere to go. Layer in a Mid-Atlantic summer that keeps windows shut for months and a winter that does the same, and it is easy to see why so many homeowners in the area deal with allergy flare-ups, musty odors, or dust that never seems to disappear. The steps below can help you fix poor air quality in your house before it turns into a bigger comfort or health concern.

Everyday Habits That Improve Air Quality

A few small changes in your routine can make a real difference in how your home feels to breathe.

Change Your Air Filter on Schedule

A clogged air filter cannot catch dust and allergens the way it should, and it forces your furnace or AC to work harder in the process. Most homes do best with a filter change every one to three months, though homes with pets or multiple occupants may need it sooner.

Control Indoor Humidity

Northern Virginia summers bring heavy humidity indoors, which feeds mold, dust mites, and that lingering musty smell. Keeping humidity between 30 and 50 percent helps stop moisture problems before they start.

Clean and Dust Regularly

Dust, pet dander, and pollen settle into carpets, curtains, and furniture, then get stirred back into the air every time your system kicks on. Regular vacuuming and dusting keep less of it circulating in the first place.

Ventilate When You Can

Opening windows on mild days lets fresh air in and gives trapped pollutants a way out. It is a simple habit that costs nothing and helps your home’s air feel noticeably lighter.

Professional Upgrades Worth Considering

Once the basics are covered, a few professional upgrades can take your home’s air quality further than habits alone.

Upgrade to Whole-Home Air Filtration

A standard one-inch filter is built to protect your equipment, not to capture the fine particles that trigger allergies. Whole-home air filtration is designed to pull far more dust, pollen, and airborne particles out of your air with every cycle.

Add a Whole-Home Dehumidifier or Humidifier

If your home swings between sticky summers and dry winters, a whole-home dehumidifier or humidifier can keep humidity balanced year-round instead of relying on portable units that only cover one room at a time.

Install a UV Air Sanitizer

A UV air sanitizer works inside your ductwork to help reduce mold, bacteria, and other growth that a filter alone cannot catch. It runs quietly in the background, giving your filtration an extra layer of protection.

Schedule Regular Duct Cleaning and Maintenance

Even a great filter cannot fix ductwork that is already carrying years of dust and debris. Our guide on how often to schedule duct cleaning breaks down how to tell when it is time, and our air filter guidelines cover what to look for between visits.

Putting It All Together

None of these steps have to happen at once. Start with the habits that cost nothing, like filter changes and regular dusting, then add professional upgrades as your budget allows. Homeowners who combine both usually notice less dust, fewer allergy flare-ups, and a home that feels easier to breathe in every season.

If dust, allergies, or musty air have become a regular part of life in your Sterling, Ashburn, or Reston home, Meade’s Heating and Air is ready to help. Our NATE-certified technicians can walk through your home, point out what is affecting your air, and recommend solutions that fit your household rather than a one-size-fits-all fix.

8 Major Pollutants of a Home’s Indoor Air

Written by Kevin on September 13, 2022. Posted in air quality.

The quality of air we breathe indoors is just as important as the air we breathe outdoors. Unfortunately, many homes have indoor air pollution levels that are higher than outdoor levels. This is because homes are tightly sealed to save energy, and consequently, they trap pollutants inside. Here are some of the major pollutants of a home’s indoor atmosphere.

1. Volatile Organic Compounds (VOCs)

Volatile organic compounds are a group of chemicals that are emitted as gases from certain solids or liquids. VOCs are emitted by a variety of common household products such as cleaning supplies, paints, and adhesives. In addition, they can also come from other sources such as automobiles and dry cleaners. VOCs are especially harmful to human health because they can easily be inhaled.

Once inside the body, they can cause a variety of health problems, including headaches, nausea, and respiratory problems. In extreme cases, long-term exposure to volatile organic compounds has been linked to cancers of the liver, kidneys, and blood. For these reasons, it is important to take steps to reduce the level of VOCs in your home. Some simple ways to do this include ventilating rooms where you are using products that contain VOCs and choosing low-VOC products whenever possible.

2. Radon (Rn)

Radon is a colorless, odorless, radioactive gas that occurs naturally in the environment. It is produced by the breakdown of uranium in rocks and soil, and it can enter homes through cracks in the foundation or other openings. Radon is a health hazard because it can build up to high levels in enclosed spaces, and exposure to high levels of radon has been linked to lung cancer. The risk of lung cancer from radon exposure increases with both the level of radon and the length of time of exposure. However, the risk of lung cancer from radon exposure can be reduced by taking steps to reduce radon levels in the home.

3. Asbestos

Asbestos is a naturally occurring mineral fiber that has been used in a variety of commercial and industrial applications for many years. It is recognized as a leading cause of mesothelioma, a rare and aggressive cancer that develops in the lining of the lungs. Asbestos fibers are also known to cause other health problems, including lung cancer and asbestosis (a chronic lung disease).

Although asbestos was once widely used in insulation, flooring, shingles, textiles and other products, its use has been dramatically reduced in recent years due to health concerns. Today, asbestos is most commonly found in older homes and buildings. When these materials deteriorate or are disturbed, asbestos fibers can be released into the air, where they can be inhaled by people nearby. This exposure can lead to serious health problems, so it is important to be aware of the risks associated with asbestos and take steps to avoid exposure.

4. Biological Pollutants

Biological pollutants, also known as bioaerosols, are tiny particles of living or once-living organisms that are suspended in the air. Common sources of bioaerosols include mold, dust mites, pet dander, and pollen. Bioaerosols can also be released into the air when we breathe, sneeze, or cough. While most bioaerosols are relatively harmless, some can cause serious health problems. For example, exposure to mold spores can trigger allergies and respiratory infections, while exposure to certain types of bacteria can lead to food poisoning.

In people with weakened immune systems, bioaerosols can even cause serious and potentially fatal infections. As a result, it is important to take steps to reduce the level of bioaerosols in your home. Some simple measures include regularly cleaning surfaces that collect dust, using air filters to remove allergens from the air, and vacuuming carpets and upholstered furniture regularly.

5. Formaldehyde

Formaldehyde is a colorless, flammable gas at room temperature and has a strong, distinct smell. Formaldehyde is produced naturally by all animals as part of their metabolism, but most exposure to formaldehyde comes from man-made sources. Formaldehyde is used in many household products, such as glues, adhesives, pressed-wood products, and insulation materials. It is also used in funeral homes as an embalming fluid. When these products are used or stored indoors, formaldehyde can be released into the air.

Formaldehyde exposure can cause irritation of the eyes, nose, and throat. In some people, it can cause asthma attacks and difficulty breathing. Some studies have also suggested that formaldehyde exposure may increase the risk of certain types of cancer. To reduce your exposure to formaldehyde, choose household products that contain little or no formaldehyde and ventilate your home well when using these products.

6. Nitrogen Dioxide (NO2)

Nitrogen Dioxide (NO2) is a colorless, odorless gas that is produced when various fuels are burned. It is released from power plants, car exhausts, and other sources of combustion. NO2 can cause a variety of health problems, including respiratory irritation, coughing, and difficulty breathing. In extreme cases, it can lead to pulmonary edema. NO2 is especially dangerous for children, the elderly, and people with respiratory conditions such as asthma. For these groups of people, even short-term exposure to high levels of NO2 can be life-threatening.

Fortunately, there are things that people can do to reduce their exposure to this harmful pollutant. Indoor air quality can be improved by ventilating homes and businesses with fresh air, using HEPA filters to remove NO2 from the air, and avoiding the use of products that release harmful chemicals into the air.

7. Lead (Pb)

Lead is a chemical element found in the earth’s crust. Although it has some benefits, lead is also poisonous and can cause serious health problems if it is inhaled or ingested. Lead exposure can damage the brain, kidneys, and nervous system. It can also cause anemia, high blood pressure, and fertility problems. Young children and pregnant women are especially vulnerable to the effects of lead poisoning.

Lead is commonly found in old paint, pipes, and solder. It can also be found in water sources that contain high levels of lead. Some industries release lead into the air, which can eventually settle on surfaces indoors and contaminate dust and soil. People can be exposed to lead by inhaling lead-contaminated air, eating food that contains lead, or drinking water that contains lead. It is important to take steps to prevent exposure to this pollutant.

8. Cookstoves and Heaters

These devices emit harmful gases and particles into the air, which can cause adverse health effects. The most common pollutant emitted by cookstoves and heaters is carbon monoxide (CO). This gas can cause headaches, dizziness, and even death in high concentrations. Additionally, cookstoves and heaters can also emit other harmful pollutants, such as nitrogen dioxide and particulate matter. These pollutants can cause respiratory problems, including asthma. Therefore, it is important to ensure that your cookstove or heater is properly ventilated to minimize the risk of exposure to these harmful pollutants.

Various Ways to Check the Air Quality in Your Home

Written by Kevin on May 18, 2022. Posted in air quality, HVAC.

Air pollution is one of the top environmental threats to human health today. That’s why it’s so important to check the air quality in your home regularly. An unhealthy environment is not just uncomfortable and unpleasant — it can also be dangerous. Improving this situation can lower your risk of developing health problems, and it can save you money by reducing the number of sick days you take each year. Keep reading to discover some easy ways to check the air quality in your home.

Invest in an Indoor Air Quality Monitor

An indoor air quality monitor is a simple and inexpensive way to check the air quality in your residence. The EPA recommends that everyone have one in their home by 2025. The main advantage of an indoor air quality monitor is that it allows you to check how healthy your home’s air is at any given time. This can be very beneficial because many issues can be avoided if you catch them early on. You can also use this information to help improve your home’s air quality over time.

Check the Signs of Mold Growth

Mold is a common household problem, but it’s also one of the most dangerous. If you live in Northern Virginia where mold is prevalent, you should make sure that you check the quality of the air in your home regularly. Mold can grow even in relatively clean environments, so it’s essential to check now and again. Look out for the following signs:

Smell

Mold often produces a musty or mildew-like smell. It can be challenging to detect this smell because mold can grow on many different surfaces. For example, your bathroom may have no noticeable signs of mold growth yet still display a musty smell. This means that there is likely some type of mold growing on its surfaces. It would help if you also looked for any visible signs of mold growth, such as black spots or white dust on your walls or ceiling or discoloration on your furniture and carpets.

Appearance

Mold often produces a fuzzy appearance. This is because mold tends to grow on damp and dark surfaces such as the walls of your bathroom, closets, and basements. You can check for this by examining the walls in your bathroom and seeing if they have this fuzzy look. If you see this, there may be some type of mold growing on them.

Use an Air Purifier to Improve Air Quality

An air purifier is a great way to improve the air quality in your home. They are relatively inexpensive, and they can be used almost anywhere in your residence. There are many types of air purifiers on the market today so that you can choose the right one for you. The most common type is a HEPA filter air purifier, which uses an electrostatic charge to remove particles from the air. These air purifiers are also very effective at removing dust and pollen from indoor environments. They can also eliminate odors, smoke, and other chemicals from the air you breathe.

Perform a Home Radon Test

Radon is a colorless, odorless, and tasteless gas created by the breakdown of natural radioactive materials found in soil. According to the Environmental Protection Agency (EPA), it is also the leading cause of lung cancer in the United States. Radon can be found in all 50 states and can be released from your home into the air through cracks or openings in the foundation. The EPA recommends that all homes be tested for radon to ensure no harmful levels are present. You can purchase radon test kits from your local hardware store or buy them online. You will need to test your home for radon at least once every three years and perform a test on each level of your home, including the basement.

Install a Carbon Monoxide Detector

Carbon monoxide is a colorless, odorless, and tasteless gas that can be dangerous to humans if they are exposed to it. This invisible threat can be produced by a faulty furnace, water heater, or any other combustion device. It is also a silent killer and does not produce any symptoms until it has reached a high level in the air and a high concentration in the body. What you can do about this is install a carbon monoxide detector on each level of your home. They are relatively inexpensive and very easy to use.

Change Air Filters Regularly

Air filters are used to filter the air inside your home. They can be purchased at a hardware store or online. The type of filter you buy will depend on what kind of air purifier you have in your house: HEPA or activated carbon. The HEPA filter is an air purifier that uses an electrostatic charge to remove particles from the air. They are relatively expensive and should be replaced every three to four months. The other type is a carbon filter, which is a more affordable option that uses activated charcoal to remove particles from the air. These filters should be replaced twice a year, depending on the demands of your home and where they are located.

Notice an Increase in Allergy Signs

Allergies are common health problems that affect millions of people in the United States. They can be caused by various things, including dust mites, mold, pet dander, and pollen. It is recommended that you have your home professionally treated for these types of allergens to ensure that you do not develop any more symptoms. You may also notice a change in the odor or even the color of your home’s air. This is because certain substances can alter these, so it is best to have the situation evaluated by your home service professional.

Have Your Home Inspected

If you notice any changes in how your home smells or feels inside, you may want to have it assessed by a professional inspector. The inspector will look at all aspects of the residence and address any intrinsic issues. These range from structural concerns or damage to materials in the environment such as toxins or radon. They will also evaluate whether there are any leaks in pipes or if there are any cracks in the walls.

Rely on Local Experts

As you can see, there are some great ways to prevent mold in your home and preserve the indoor air quality. It would help if you tried to implement as many of these as possible.
