For many individuals living with asthma, it can be difficult to manage the severity of their symptoms on a daily basis. One solution that has been gaining popularity is the use of air purifiers as an effective way to combat asthma-related symptoms. But how exactly does an air purifier help with asthma? Keep reading to find out if an air purifier could potentially be beneficial for you or your loved one who suffers from this condition.

What is asthma and what are the common symptoms?

Asthma is a chronic lung condition that can affect people of all ages. It causes the airways to become inflamed and narrow, making it difficult to breathe. Asthma flare-ups or ‘attacks’ are characterized by symptoms such as coughing, wheezing, chest tightness or pain, and difficulty breathing. Common triggers of asthma flare-ups include exposure to pets and other allergens like dust mites, irritants in the environment such as smoke or perfume, changes in weather conditions (cold air), exercise, and stress. People with asthma may also experience fatigue due to poor sleep quality caused by their symptoms at night which further affects their overall health. With proper management and treatment from qualified medical professionals, individuals with asthma can live healthy lives free from frequent attacks.

How Does An Air Purifier Help With Asthma?

Learn how an air purifier works to filter the air and what kind of air purifier may be helpful for asthma sufferers, so you can take control of your breathing environment!

 How it works to filter the air

An air purifier works by pulling air from your living space, running it through the filter(s) to capture particles and allergens, and then releasing the clean air back into your home. Air purifiers have multiple levels of filtration – often pre-filters, HEPA filters, and activated carbon filters – that work together as a system to provide maximum protection against asthma triggers.

Pre-filters are designed to trap larger particles such as dust, pet dander, and mold spores before they reach the other filters. This helps protect them from becoming clogged more quickly. The main filter used in most systems is HEPA (high-efficiency particulate air) which can capture 99.97% of airborne particles down to 0.3 microns in size including pollen and bacteria. Activated carbon filters have adsorption properties that allow them to absorb odors caused by smoke, chemicals, or other volatile organic compounds (VOCs).

An air purifier can be an invaluable tool for those with asthma because it works 24/7 to constantly remove potential asthma triggers from the indoor environment while significantly improving the overall quality of life within your home or workspace.

What kind of air purifier will help with asthma

When it comes to choosing an air purifier for asthma, there are a few things you should consider. For starters, the most important thing is ensuring that your air purifier has an effective filtration system. Make sure to look for one with HEPA filters, as these trap 99.97% of particles as small as 0.3 microns in size – which includes dust mites, pet dander, and pollen that can trigger asthmatic reactions. Additionally, since ozone emission can actually worsen asthma symptoms and irritate the lungs, make sure you opt for an ozone-free air purifier model.

Another factor to keep in mind is the size of the room you’ll be using your air purifier in – many models list their recommended maximum coverage area so you have an idea of whether or not they will effectively cleanse your household’s indoor environment from allergens or other airborne contaminants. Lastly, always check if it has any relevant certifications such as being Energy Star certified and/or having medical-grade ratings– this way you can be sure that your chosen product meets all health safety standards for use in homes with asthma sufferers.

Benefits of Using an Air Purifier for Asthma

An air purifier can not only improve your breathing but also reduce the number of asthma attacks and provide a better quality of air for you. Read on to learn more about how it works and its benefits!

Improved breathing

For those who suffer from asthma, improved breathing is a must. Not only does it make life easier and more enjoyable, but it can also help ward off the symptoms of asthma, such as wheezing, coughing, chest tightness, and difficulty breathing. An air purifier can help improve the quality of your indoor air and reduce airborne allergens that trigger allergic reactions or flare-ups in some asthmatics. Because most air purifiers are equipped with a high-efficiency particulate air filter (HEPA), they are able to trap airborne particles like dust mites, mold spores, pet dander, pollen, and other allergens that can cause an uptick in symptoms for someone with asthma. The improved breathing capacity helps people who suffer from this condition enjoy activities without having to worry about triggering an attack or worse – being sent to the hospital due to poor health.

Reduced asthma attacks

For asthmatics, the use of an air purifier can be a great way to reduce asthma attacks. An air purifier helps to remove particles in the air that could potentially trigger asthma attacks and make breathing difficult. This includes dust mites, pet dander, mold spores, pollen, smoke, and other airborne allergens. By filtering out these pollutants from the air inside your home or office space, you can reduce the risk of asthma flare-ups and help keep your family’s health intact. In fact, some studies have even shown that using an air purifier has reduced symptoms for people with mild to moderate allergies or asthma-related issues.

The type of filter used matters when it comes to reducing asthma attacks – HEPA filters work best in trapping small particles including bacteria and viruses which are important components that lead to irritation and inflammation in individuals with respiratory conditions such as asthma. Look for certification labels such as AHAM (Association of Home Appliance Manufacturers) when purchasing an air purifier since those products have been tested for their performance according to strict standards set by this organization. Furthermore, make sure the unit you buy is ozone free since ozone can actually worsen existing respiratory problems like asthma!

Better air quality

Homeowners with asthma know the importance of having good air quality in their homes. An air purifier is a great option for improving the air quality in your home and preventing the triggers that cause asthma attacks. Air purifiers work by removing airborne particles, such as dust, pet dander, smoke, bacteria, pollen, and other allergens. This helps to reduce indoor air pollutants which can aggravate symptoms of asthma or trigger an attack. By running an air purifier regularly in your home you can help to improve the overall air quality and provide relief from unpleasant odors caused by these pollutants. In addition to filtering out airborne particles, some models also absorb odors and sterilize germs that could worsen respiratory conditions. With improved air quality, you can breathe easier without worrying about irritating side effects from poor ventilation or polluted indoor environments.

Selecting The Right Air Purifier

Choosing the right air purifier, based on efficiency, room size, certification, and ozone-free technology can have a huge impact on your asthma symptoms, so make sure to take the time to select the best one for your needs!


When it comes to asthmatic relief, a clean air purifier needs to be efficient enough. Efficiency means that the air purifier must quickly filter out pollutants and toxins from the indoor air so that you can breathe easier. That is why when looking for an air purifier suitable for asthma, pay attention to its efficiency level, rated in CADR (Clean Air Delivery Rate). The higher the CADR rate of your chosen model, the better it will perform in removing airborne particles like dust mites and pet dander. Another key feature is the HEPA rating. A True HEPA filter removes 99.97% of airborne particles down to 0.3 microns or smaller in size which makes them highly effective at reducing allergens and irritants while improving indoor air quality overall.

Room size

For a homeowner with asthma, the size of the room is an important factor to consider when selecting an air purifier. Depending on the size of the room or space, you should purchase an air purifier that is capable of cleaning at least 2-3 times the volume of air in your area. A larger air purifier will be able to filter more particles from the air compared to one intended for a smaller space. For instance, if your living room is 200 sq ft., you should buy a unit rated for 600 sq ft minimum. This way it won’t become overwhelmed by large amounts of impurities and debris present in your home. Additionally, for bigger rooms or spaces such as basements and attics you need even more powerful machines that can clean up to four times their rated square footage. If possible try experimenting with different models to find out which works best in the environment before making any purchases.


When selecting an air purifier for asthma, it’s important to make sure that the product is certified safe and effective. The most reliable certification comes from organizations such as the Association of Home Appliance Manufacturers (AHAM), which verifies that air cleaners reduce particle levels in a room as specified by their label. Look for AHAM certification when shopping for an air purifier. You may also see products labeled with Energy Star or CarbonFootprint certifications, indicating that they meet certain energy efficiency standards or have a minimal environmental impact. While these certifications aren’t necessarily related to asthma relief, they can be helpful to consider depending on your needs.


When it comes to selecting the right air purifier for asthma, choosing an ozone-free unit is essential. Ozone is a powerful oxidizing agent found in polluted outdoor air and can aggravate symptoms of asthma. Ozone generators in air purifiers create particles that are small enough to penetrate deep into your lungs and lead to inflammation, chest tightness, coughing, and other respiratory distress. When shopping for an air purifier, make sure to look for one that clearly states “no ozone emission” or “ozone free” on the label or product description. This will ensure you get a device safe from potential health hazards caused by ozone exposure.

Are There Any Precautions to Using an Air Purifier for Asthma?

It’s important to be aware of the potential risks associated with air purifiers, so make sure to read on to learn more about how you can safely use an air purifier for asthma!

Choosing the right filter

For homeowners dealing with asthma, the importance of choosing the right filter for your air purifier can’t be stressed enough. You want to make sure that all the common asthma triggers like dust mites, pet dander, pollen, and smoke are eliminated from your indoor environment. The best way to do this is to choose a filter designed specifically for these materials so that it eliminates them from the air before they enter your lungs. HEPA (High-Efficiency Particulate Air) filters have been proven effective in trapping these substances as small as 0.3 microns in size and ensuring clean air circulation in your home or office space. However, if you live with any smoke-producing activities such as smoking indoors or burning incense regularly, then you should opt for a carbon-activated filter which is better at eliminating odors and gas particles rather than allergens and other airborne particles like dust mites or pet dander.

Avoiding ozone

For those looking to use an air purifier for asthma, one of the most important precautions is avoiding ozone-emitting filters at all costs. Ozone is a naturally occurring gas in the air that can cause breathing problems and exacerbate asthma symptoms. If you’re considering buying an air purifier with ozone removal capabilities, make sure to check it thoroughly before purchasing to ensure it is actually removing the ozone from your home rather than producing more. Additionally, consider getting an indoor air quality monitor if possible so you can track how much ozone is present in your home and around your air purifier.

Tips for Using an Air Purifier for Asthma

By implementing a few simple tips and tricks, you can maximize the benefits of using an air purifier for your asthma and ensure improved breathing in your home.

 Creating optimal ventilation

Creating optimal ventilation is a key factor to consider when using an air purifier for asthma. Without proper airflow in the room, the air purifier can only do so much to filter out the allergens and pollutants from your indoor air. Opening windows or adjusting vents helps increase airflow while also decreasing humidity levels in the house. Furthermore, turning on any ceiling fans that you may have in your home will help to better circulate the clean air produced by your purifier more evenly throughout the space. This helps ensure effective coverage of purified air and makes sure that any allergens present are quickly and efficiently removed from the surrounding environment.

Keeping the filter clean

It is important to clean the air purifier filter regularly in order to ensure that it is working properly and efficiently. Depending on the type of filter you have, it may need to be cleaned anywhere from once a month up to every two months. Keep an eye on the color of your filters; when they start taking on a darker hue than usual, this usually indicates that it’s time for a cleaning. For example, if you have HEPA filters in your air purifier which are designed to capture ultrafine particles like dust and pollen, then chances are high that these will collect dirt more quickly over time. So make sure to check them often! The best way to clean any type of filter is by wiping them down with warm water or lightly vacuuming them only with low suction. This should get rid of any large particles while allowing the filter material itself to remain intact and effective at capturing contaminants in the air.

 Other Home Remedies for Asthma

In addition to an air purifier, there are several other home remedies that can help with asthma, such as humidity control and avoidance of triggers. Learning more about these home remedies can provide added peace of mind and make living with asthma easier!

Humidity control

Humidity is an important factor to consider when it comes to controlling asthma symptoms. Higher than normal levels of humidity in the home can increase the likelihood of allergens being present, and this can lead to more severe asthma attacks. By keeping your home’s air between 30%-50% relative humidity you will reduce mold, dust mites, and other pollutants that may worsen asthma symptoms. Devices like a dehumidifier or air purifier with a dehumidifying function can help maintain appropriate humidity levels in your home while also filtering out harmful particles from the air which will ultimately reduce asthma flare-ups. Additionally, ensuring good ventilation throughout your house by opening windows or using fans will circulate fresh air as well as manage indoor moisture levels.

Avoid triggers

For those with asthma, it is important to avoid triggers that can set off an attack. Common airborne allergens and irritants include pet dander, dust mites, mold spores, and pollen. Other environmental irritants such as smoke from tobacco or wood-burning fireplaces may also trigger an attack. Identifying and avoiding these triggers is the best way to prevent or reduce the severity of asthma attacks. An air purifier can help remove common airborne allergens from your home’s environment, reducing their impact on your health and providing relief for asthmatic symptoms.


Living with asthma can be difficult, but there is hope. An air purifier can help improve your breathing and reduce the number of asthma attacks you experience. With the right purifier, certified to not produce ozone, you will benefit from improved air quality while keeping your home free of triggers. Regularly maintaining your air purifier will also ensure that it remains as effective as possible in filtering out allergens and pollutants that can cause an asthma attack.
