How an Air Purifier Can Help Asthma Sufferers

Here’s something you may not know…

  • According to the Environment Protection Agency (EPA), indoor air quality in our homes is 2-5x worse than the outdoors.
  • WebMd also concluded that 1 out of every 5 Americans is a victim of asthma and allergy related issues.

With those two statistics in mind, you can see why the demand for air purifiers has skyrocketed. You can also understand why it makes sense to have one in your home in order to improve your health.

For many of you that suffer from asthma, indoor air quality is usually the culprit for asthma symptoms and attacks.

Since we tend to keep the doors and windows to our homes shut (creating an airtight seal) and unknowingly bring in harmful toxins from the outdoors (through our clothing and shoes), our homes become infested with particles that have no way to escape.

In fact, we’re essentially locking ourselves inside a box with millions of contaminants that continue to circulate and never get cleaned out. For asthma sufferers, this becomes a perpetual pain for your lungs.

Fortunately, there is a cure.

The best air purifier for people who have asthma is one that removes 99.97% of asthma-inducing toxins from the air that cause irritation. This includes dust, mold spores, pollen, and bacteria.

Without these harmful particles roaming free in your home, you end up with an indoor space that’s packed with only clean, fresh air. This means that you can breathe easier, feel better, and not have to worry about having as many asthma problems while indoors.

For asthma sufferers, air purifiers are the best solution for getting rid of the harmful triggers that cause asthma attacks.

This leads us to our next important point.

The Best Asthma Air Purifier Type to Get and Which to Avoid

An extremely important factor you must understand is that there is only one type of air purifier for asthma sufferers that is best for your health.

In fact, choosing the wrong type of air purifier will actually cause your asthma symptoms to get worse – which is the opposite of what we want. Just because a product is on our top air purifiers list doesn’t mean it will work for an asthmatic.

People who have asthma should avoid “Ionic” and “Ozone” air purifiers.

  • Air purifiers that use ionization or produce ozone actually make your asthma symptoms worse
  • These types of air cleaners emit fine particles into the air that cause lung irritation for asthmatics

What you want instead is an air purifier that has been rated to be the best for asthma sufferers.

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.

HEPA-type and HEPA-grade air filters only remove toxins as small as 3-5 microns, which misses a lot of the pollutants that irritate your lungs.

If you have respiratory issues, the best asthma air purifier to get is a True HEPA air purifier. Period.

A True HEPA air purifier works wonders for asthma sufferers by continuously cleaning the air and trapping harmful particles inside a filter. The filter then prevents these contaminants from recirculating into the air. The result is fresh, clean air that keeps asthma problems under control.

Now that you know what type of air purifier for asthma to get, and which to avoid, you’ll find below the three best products on the market that are perfect for asthmatics.

The Best Air Purifiers for Asthma Sufferers

#1 Best Air Purifier for Asthma

If you’re looking to find an asthma air purifier that not only rids your house of asthma-inducing toxins but is also super stylish, this is it.

Measuring only 7 inches in depth this product can be placed almost anywhere inside a room and also has the ability to be wall mounted.

The one-of-a-kind 6-stage air filtration system is the most efficient system on the market and was specifically designed to eliminate the largest range of allergy and asthma-inducing contaminants.

It uses a special BioGS HEPA filter that has the same efficiency as a True HEPA filter, but it last much longer before needing a replacement (up to 3 years).

When buying this product you’re given the choice of customizing one of the major filters. You can choose between:

  • Germ Defense
  • Odor Remover
  • Toxin Absorber
  • and Pet Allergy

Depending on what other types of allergens you want to get rid of, the MinusA2 has you covered, and the filters last up to 1-2 years depending on use.

This air cleaner can also purify an area up to 700 sq. ft., which is perfect for most everyone’s needs. It also includes the Energy Star certification to ensure low operating costs.

#2 Best Asthma Air Purifier

second best air purifier for asthma by BlueAir 203WBlueair 203

The second best air cleaner for asthma sufferers is the Blueair 203.

This device is unlike any other on the market because it uses a specialized HEPASilent® filter that can remove toxins as small as 0.1 microns. That’s 200% finer than what a standard True HEPA filter can capture (0.3 microns).

This air purifier has also be designed to reduce the level of ozone in the air, making every breath you take fresher than other air purifying products.

As we mentioned above, ozone particles are one of the biggest triggers for asthmatics and this product is excellent at combating them.

The HEPASilent technology also offers super-silent operation and you’ll hardly notice that it’s running. It has also been independently verified by the Association of Home Appliance Manufacturers (AHAM) and includes the Energy Star certification – making it inexpensive to operate.

Just like our #1 recommendation, the sleek design of the 203 will complement any room.

The only drawback is that it can only purify a space up to 240 sq. ft. which is less than half that of the Minus2A. However, if you don’t need to purify a very large space, this the best asthma air purifier for you to consider because it can save you around $100.

#3 Best Choice

If you’re looking to save the most amount of money while still getting relief for your asthma at home, this air purifier is going to be your top pick.

With this product, you’re getting a 3-stage air filtration system that includes a pre-filter for capturing the largest particles, a True HEPA filter for trapping the widest range of asthma-inducing contaminants, and an Activated Carbon filter for reducing airborne gases and chemical irritants.

For less than half the cost of our #2 pick, you can have a powerful little air purifier that covers a bedroom or living room up to 322 sq. ft.

Common Questions Asthmatics Have about Air Purifiers

Do air purifiers help with asthma?

Yes. Air purifiers remove airborne contaminants that are responsible for triggering asthma. This includes things like dust, pollen, smoke, pet dander, mold, and other irritants. Air purifiers strip pollutants out of the air and replace it with clean, fresh air for you to breathe.

Are air purifiers bad for asthma?

Some air purifiers can be bad for asthma while others are not.

The bad air purifiers include ozone generators and ionizers which emit particles into the air as a way to clean it. Those particles have been known to irritate lungs of asthmatics and cause difficulty breathing. Therefore it’s best to stay away from those kinds of air cleaners if you have asthma.

The best air purifier for helping reduce asthma symptoms is one that uses a True HEPA filter. This filter doesn’t emit any harmful byproducts and is capable of removing 99.97% of contaminants that cause asthma symptoms.

Are ionisers good for asthma?

No. Ionisers emit negatively charged ions into the air as a way to clean it and these particles can often make your asthma worse. It’s best to stay away from ionisers when looking for an air cleaner for your home.

What is the difference between an air purifier and ionizer?

Both air purifiers and ionizers are devices that clean the air. The way they differ is in the way they perform the air cleaning function.

Air purifiers draw air inside the unit and pass it through a set of filters to trap airborne pollutants. Clean air is pushed out the other side.

Ionizers send ions out into the air that latch on to pollutants. The extra weight of this ionic bond causes pollutants to fall out of the air and onto the ground.

Both methods of air purification work, but air purifiers that use a True HEPA filter are much more efficient and safer for people with asthma.

What is the best air purifier for people with asthma?

The Rabbit Air MinusA2 is one of the best air purifiers for asthma. This air purifier uses 6-stages of air filtration to purify the air of the most common asthma-inducing contaminants.

Although it does include an optional ionizer function, only an amount of 0.002 ppm (parts-per-million) was recorded at low fan speed with it turned on. That is 25 times less than the 0.05 ppm maximum ozone concentration safety standard set forth by the California Air Resource Board.

Does fresh air help asthma?

Yes. Fresh air is essential for reducing asthma-related symptoms and attacks.

Asthma is often triggered by airborne irritants that get into the lungs and cause a negative respiratory response such as mold spores, pollen, pet dander, dust, and other allergens.

When you run the best asthma air purifier in a room, it cycles the air through a series of filters that strips out these pollutants. The result is clean air for you to breathe that doesn’t include particles that irritate asthma.

Additional Ways to Help with Asthma at Home

While an air purifier is one of the best devices you can buy for your home to help with asthma, there are several other steps you can take to help reduce or alleviate your symptoms.

One of the easiest things you can do is reduce the number of fabrics, carpet, and upholstery that is inside your home or a specific room. These objects are breeding grounds for asthma-inducing particles because they trap them within the woven fibers that make up their elements.

If you can replace any of those types of objects with other options it can help cut down a lot. For example, removing the carpet within a room and replacing it with laminate or wood flooring will remove a notorious collection spot for asthma triggering contaminants. The same thing goes with replacing drapes with plastic or wooden blinds.

If you have pets, it’s best to bathe them at least once per month, but ideally every 1-2 weeks. This will cut down on the amount of pet hair and dander they emit, which highly affects asthma.

For bedrooms, buying dust mite covers for your bedding will keep these critters from making a home in your pillows and mattress. A small one-time investment in these items can be a great benefit for an asthmatic.

Finally, many asthmatics are affected by the humidity levels within a home. In addition to getting the best air purifier for asthma, adding a humidifier or dehumidifier to properly maintain the right humidity level is a wonderful combination of technology to have in place.

A hygrometer will help you figure out what the humidity levels are inside your home, which will alert you to which type of humidifying device to get. The key here is that you want the level to be between 30-50%.
