Frequently Asked Questions

Do air purifiers help with asthma?

According to research, air purifiers do help asthma. An air purifier can be an effective device for helping relieve asthma symptoms in adults and children. This study indicates that HEPA air purifiers can reduce indoor particulate matter concentrations by approximately 25% to 50% which can help reduce asthma symptoms and exacerbations.

How does an air purifier help with asthma?

What makes an air purifier good for asthma is the fact that it strips the air of any particles that cause your symptoms to flare up. By creating clean, fresh air inside your home, you’ll notice an overall improvement in your health. You’ll be able to breathe easier, get around better, and not have as many sudden asthma attacks.

However, you do need to get a specific type of air cleaner if you want it to work properly. Buying the wrong type can actually make your asthma worse.

Do doctors recommend air purifiers?

Doctors do recommend air purifiers for some patients who have certain medical conditions. Research shows that filtering the air can help remove harmful particles from indoor spaces, particularly allergens, mold spores, and smoke as long as it has an approved HEPA filter.

However, doctors do not recommend air purifiers as the only remedy for respiratory and allergy issues. That’s because even the best air purifier for asthmatics is not a cure-all for environmental conditions, diet, and general health practices.

What size asthma air purifier should you get?

True HEPA air filters come in a variety of sizes and you need to make sure that you get an air cleaner for asthma that’s capable of cleaning the room (or several connected rooms) that you want to use it in. This function is especially important if you are a severe asthma sufferer or allergies.

To help you get the right size air cleaner for your needs, we listed the total square footage coverage for each allergy and asthma air purifier on this page.

And if you don’t know the square footage of the room you want to use the air purifier in, just use this simple formula:

  • Width X Length = Total Square Feet (sq. ft.)


  • 15′ X 20′ = 300 sq. ft.
  • 26′ X 30′ = 780 sq. ft.
  • 32′ X 35’= 1,120 sq. ft.

Can air purifiers make asthma worse?

Some air purifiers can make asthma worse. If the air purifier produces a type of gas called ozone, then it can irritate your lungs and make your asthma worse. Avoid products labeled as “air ionizers” or “ozone generators” as they are bad for asthmatics.

HEPA air purifiers do not worsen asthma because these devices don’t produce ozone or any other by-products. The best HEPA air purifier for asthma sufferers, like the units reviewed on this page, can help your symptoms improve over the long-term.

Why are ionizers bad for asthma?

Ionizers are bad for asthma because they can generate ozone which is a known lung irritant for asthmatics that causes chest pain, coughing, shortness of breath, and throat irritation. Air ionizers also emit negatively charged ions into the air that can also inflate asthma symptoms.

We go over this topic in-depth in our ionizer and asthma article. We also talk about are air purifiers good in general. So take a look at those pages if you want to learn more about this issue.

Does an air purifier help with breathing?

An air purifier does help with breathing. Air purifiers clean the air in your home so you breathe in fewer particles that could irritate your, nose, throat, and lungs. A HEPA air purifier is the best type for better breathing because it can remove 99.97% of particles down to 0.3 microns.

There are many air purifier advantages, including better indoor air quality to breathe, fewer odors, less dust and dust mites, etc. If you want to learn more about what does an air purifier do to improve breathing, check out the linked articles.

Which is better for asthma: humidifier or air purifier?

An air purifier is better for asthma. Air purifiers remove particles from the air that trigger asthma symptoms. Humidifiers add moisture to the air and do not have any capability to reduce airborne allergens or other pollutants. Therefore, an air purifier is best for asthma symptoms.

The humidifier vs air purifier questions is a popular one for asthmatics. Hopefully this short answer solves your concerns.

Where should I place my asthma air purifier?

Air purifiers only work in the room (or area) that they’re placed in. Therefore, it’s best for an asthmatic to put an air cleaner in their bedroom, where we spend 6-8 hours a night, and in the main living area of the home, where contaminants tend to collect the most.

The best location inside a room is 24 inches from a wall and as close to the center of the room as possible for the most airflow.

What helps asthma at home?

There are several things that can help asthma at home, including an air purifier to remove airborne triggers, drinking caffeinated tea or coffee to open up the airways, rubbing mustard seed oil on your chest and breathing it in, sitting upright, taking slow and deep breaths to prevent hyperventilation.

When should you seek medical help for asthma?

While home remedies and an air purifier are great tools to help control your asthma at home, the truth is that these devices can only do so much to prevent or alleviate the problem.

There are still times in which you may have a serious asthma attack or difficulty breathing that requires to you seek emergency medical attention.

If any of the following symptoms occur, you should go immediately to the emergency room:

  • Experiencing severe wheezing or breathlessness that won’t let up.
  • Inability to speak full sentences because of shortness of breath.
  • Having to strain your chest muscles in order to breathe.
  • Asthma symptoms not settling after you’ve uses a rescue inhaler.

Types of Air Purifiers and Filters

There are literally dozens of different types of air purifiers on the market and each one uses a variety of air filters to purify the air. This can make it hard for the average person to know what to look for in an air purifier.

We’ll explain each of these things in detail below so you know how to choose the right air purifier for your needs.


Asthmatics should only use “True HEPA filter” air cleaners.

HEPA stands for “High Efficiency Particulate Air”, and it comes in three versions:

  • True HEPA
  • HEPA-type
  • and HEPA-grade

As an asthma sufferer, you only want a True HEPA air purifier.


Because True HEPA filters are certified to remove 99.97% of toxins as small as 0.3 microns in size from the air that trigger asthma-related symptoms and attacks.


Air purifiers that include an Activated Carbon filter are excellent at reducing odors, gases, and dangerous volatile organic compounds (VOCs) from the air.

Some of those substances can also trigger asthma and allergy symptoms as well as cause a number of health-related issues.

Therefore, getting an air purifier with an Activated Carbon filter is a smart thing to do.


UV (or ultraviolet) light technology is used to destroy airborne contaminants at a molecular level. Most commonly, UV lights are used to kill bacteria and viruses.

No other type of air purification method can kill microbes and pathogens like a UV light.


Ionic air purifiers emit charged ions into the air to weigh particles down.

They don’t trap pollutants inside a physical filter; however, some products may have electrostatic collection plates that can attract the particles from the air.

Ionic air purifiers (or ionizers) are not good for asthmatics because the charged ions can irritate asthma symptoms.

Also, some ionizers produce ozone as a by-product, and that too can cause lung irritation.


Ozone air purifiers emit ozone as a way to clean the air.

Ozone is a molecule that’s composed of three oxygen atoms and has the ability to attach to other molecules, such as smoke and odor, to clean and deodorize areas quickly.

However, ozone can also react negatively with your skin, eyes, lungs, and other exposed areas.

So, it’s never good to be in the same room as an ozone air purifier while it’s running. And, people with asthma should stay away from these types of air purifiers all together.


As an asthmatic, you’ll want to stay away from ionizers.

The short explanation for how does an ionizer work is that it sends out negatively charged ions into the air to neutralize airborne particles; however, studies have shown that these ions can make your asthma worse and may induce asthma attacks.

Also, some ionic air purifiers emit a small level of ozone as a by-product which can also worsen asthma.

Electrostatic Precipitators

Electrostatic precipitators are a type of air cleaner that uses electrically charged plates to trap particles.

Room air is drawn into the air purifier with a fan and pollutants that pass through the system are electrically charged so they stick to a set of collector plates (i.e. a metal air filter).

Depending on the size of the room and the air cleaner unit, you may have to clean the metal air filter plates daily or weekly.

Similar to ionizers, some electrostatic precipitators do produce ozone as a by-product, which can be an irritant for those who suffer from asthma. Therefore, our recommendation is to stay away from these types of air purifiers for asthma patients.

Common Indoor Asthma Triggers

There are a number of indoor triggers for asthma and an air purifier can get rid of most of them.

Everyone’s triggers are different.

So, learn to know your triggers and find ways to avoid them.

The most common triggers include:

  • Tobacco Smoke
  • Dust
  • Dust Mites
  • Outdoor Air Pollution
  • Cockroach Allergen
  • Pet dander
  • Mold
  • Smoke From Burning Wood
  • Voliatle Organic Compounds (VOCs)

Common Air Purifier Terms and Definitions

When you’re shopping for an air purifier, you’ll undoubtedly come across a number of special terms that relate to the air cleaning technologies. While these words may sound foreign to you, their concepts are not that tough to understand.

Below, are the top terms and definitions you may come across when comparing air purifiers for asthma.

Pre-filter: This is a thin layer of protection that acts as the first line of defense during the air purification process. An air purifier pre-filter traps the largest airborne particles as well as dirt and hair. This important function helps to prolong the life of the other internal filters. Most pre-filters last forever and are washable and reusable.

True HEPA Filter: This term was mentioned previously, but in short, it’s the highest standard air filter you can get for an air purifier. To carry the “True” HEPA label, the air filter must meet the strict guidelines of capturing at least 99.97% of particles as small as 0.3 microns in size. These filters are not permanent and must be replaced when they fill up with too many particles.

BioGS HEPA Filter: Rabbit Air’s special type of True HEPA filter. It’s designed in a way that allows the filter to last up to two years which is much longer than the standard True HEPA filters that need to be replaced every six to eight months.

HyperHEPA Filter: IQAir’s version of a True HEPA filter. It captures 99.95% of particles down to 0.003 microns which are 10X smaller than a virus; the smallest that exists. It’s the top performing air filter for removing allergens of all kinds.

Activated Carbon Filter: This filter is specially designed to remove particles that produce odors inside the home. It works by adsorbing the molecules into the filter medium and trapping them there. An activated carbon air filter is also good for reducing volatile organic compounds which can also trigger asthma symptoms. We explain this concept more in our guide on do air purifiers help with smells.

V5 Cell Gas & Odor Filter: IQAir’s patented filter that eliminates gas and odors by combining two types of media. The first media adsorbs odors and gases while the second changes the pollutants to an oxidized form. The V in “V5” refers to the V-shaped media chambers that allow for higher airflow than comparable units.

Ionizer: Another term that was mentioned earlier in this guide, but in short, this type of air cleaner doesn’t use filters to reduce airborne pollutants. Instead, it emits negatively charged ions into the air that latch onto particles to weigh them down. This causes the contaminants to fall out of the air and land on surrounding surfaces. But are ionizers safe? Negative ions can irritate asthma and some ionizers emit ozone as a by-product which also creates problems for asthmatics.

PECO: A proprietary technology by Molekule that eliminates indoor pollutants at a molecular scale. A light shines onto a filter membrane coated with proprietary nanoparticles. This light-activated catalytic reaction on the surface of the filter breaks contaminants apart at the molecular level. Molekule makes one of the best air purifiers for allergies and asthma.

Ultraviolet UV-C Light: This technology kills airborne bacteria and viruses by destroying the DNA structure. Air passes by the UV-C light on its way out of the air purifier. A UV light air purifier is not necessarily good or bad for asthma, but it can help sterilize your indoor environment so fewer illnesses are spread. See our post on do UV air purifiers work for more details.

Air Changes Per Hour (ACH Rating): This is a specification that tells you how many times an air purifier can exchange the air inside a room every hour. The higher the number, the more efficient the device is at creating clean, fresh air. Most air purifiers give you this meaurement in the technical specifications. But if it’s missing, you can figure ACH out very quickly by following our how to calculate ACH guide.

Clean Air Delivery Rate (CADR Rating): This is a specification that tells you how well an air purifier can remove certain types of contaminants inside a room (tobacco, dust, and pollen). Only air cleaners that have been independently tested by the Association of Home Appliance Manufacturers (or AHAM) will include CADR numbers. A CADR air purifier rating can help you compare the efficiency between two or more similar air cleaners.

Air Quality Monitor: Some products only detect the level of pollutants in the air instead of filtering them out. If you come across the term “air quality monitor” when shopping for an air purifier, then keep this in mind. As we explain in depth on our air quality monitor reviews page, these units can report the various types of particles in the air and their toxicity level, but they don’t actually clean the air. If you want to know what pollutants are actually in the air you’re breathing at home, then this device can be a good supplement to your air purifier.

The company has also won several awards for its innovative product designs and received recognition from Good Design, Envisioneering Innovation and Design, and Plus X, as well as top honors in the countries of Germany and Sweden.

IQAir was founded in Germany in 1963 when two brothers–Manfred and Klaus Hammes–introduced the world’s first residential air filter.

At that time, coal ovens were popular home cooking devices and the Hammes brothers wanted to reduce indoor air pollution caused the soot. Manfred, who was an asthma sufferer, soon noticed that this radical air filter also reduced his asthma symptoms.

After Manfred passed away, Klaus continued to expand the business and in 1981 he moved the headquarters to Switzerland.

In 1998, IQAir released the HealthPro air purifier (designed by Klaus’ oldest son, Frank) and it instantly received worldwide recognition in the air cleaner market.

Since then, IQAir has earned numerous recognitions for being one of the best air purifier brands for people with serious asthma and allergies. Honorary mentions include Parent Tested/Parent Approved (PTPA) Seal of Approval, Consumers Digest Magazine’s “Best Buy” in the premium air purifier category, ConsumerSearch’s “Best Overall Air Purifier,” and Stiftung Warentest’s (Germany) “Best Air Purifier.”

Levoit was established in 2017 in Orange County, California. The company is gaining fast market share in the air purification space and has a number of top-notch air cleaners that can help with asthma, allergies, and other health conditions.

Most recently, the brand has switched from using flat filters to 360-degree filters. This new design gives their air purifiers a 40% boost in efficiency and lowers the sound output of these machines.

The Vista 200 is a great air purifier for small rooms and personal spaces.

The company has also received a number of world design awards, including the “Oscar of Industry” Reddot Award, the world-renowned design award iF, and the Global Home Innovation Awards in US CES (Consumer Electronics Show) and GIA (Gemological Institute of America).

Molekule was founded in 2014 by a sibling pair of Standford-educated engineers, Dilip Goswami and Jay Rao. The technology behind Molekule air purifiers was developed by their father, Dr. Dharendra Yogi Goswami, and it took more than 20 years of intensive scientific research to develop a new breakthrough in air purification technology: PECO (Photo Electrochemical Oxidation).

PECO filters are unique in the sense that they destroy airborne particles; not just trap them like HEPA air filters. This advanced air cleaning technology makes PECO filters effective against against chemicals, microbes, allergens, and other forms of air pollution.

The family’s mission to harness the power of science to improve lives and solve some of the world’s greatest problems by beginning with indoor air pollution.

Additional Tips for Helping with Asthma at Home

While choosing the best air purifier for allergies is a great way to remove airborne triggers that cause asthma, there are some additional steps you can take to cut down on the presence of these particles inside your home.

Combining these tips with your air purifier can help you get the most relief for your asthma symptoms.

Vacuum At Least Once Per Week

All sorts of particles can be tracked indoors on your clothing and shoes. Therefore, it’s a good idea to vacuum regularly in order to remove these contaminants from the indoor space. Like with air purifiers, you can also get a vacuum cleaner that includes a True HEPA filter. That way it will collect the finest particles possible so they don’t end up in the air you breathe.

Change Your HVAC Filters Regularly

Home heating and cooling systems use air filters to trap dust, dirt, and hair from damaging the system. The recommended interval for changing these filters is every 3 months, however, if you have severe asthma or allergies then replacing them once per month may be more helpful for you.

Minimize the Presence of Smoke

If you have asthma, reducing the use of candles, incense, and wood burning fires can help cut down on smoke particles that can irritate your lungs. Also, preventing the use of tobacco products indoors is also advisable.

Use Your Home Exhaust Fans

You can eliminate a lot of asthma triggers that are kicked up into the air while cooking by turning on the stove exhaust fan. If you don’t have one of these, opening the nearest window can also help. This same advice applies to the bathroom during and after a shower, however, the purpose of the exhaust fan in this location is to extract moisture that can irritate asthma and cut down on the production of mold spores.

Don’t Store Paint or Chemicals Indoors

Although you may have your paints, cleaning chemicals, and pesticides stored inside containers, they can still release volatile organic compounds into the air which can irritate your respiratory system. Therefore, it’s best to keep these products stored outside or in a garage or basement area that’s far away from your breathing area. For areas where this is not possible, consider getting one of the best chemical air purifier units to clean the air of these toxins.

Reduce Your Exposure to Pet Allergens

If you have pets, a good pet dander air purifier can help remove the airborne dander particles that cause asthma and allergies to flare. (Find out more here: do air purifiers help with pet dander.) However, to ensure long-term relief, it’s best to keep your animals out of the rooms where you spend the most time like a bedroom or living room. It’s also a good idea to bathe or change clothes after playing with pets, or at the very least, wash your hands to remove any pet dander particles.

Bottom Line

As you learned, the best air filter for asthma comes in two types: a True HEPA filter and a PECO filter to extract the widest range of asthma triggers from the air.

Out of all of the reviews on asthma air purifiers above, we hope you found one particular device that meets your needs. And most importantly, that it will help you live a healthier and more symptom-free life.
