How Can Air Purifiers Help with Asthma?

The way an air purifier helps with asthma is actually quite simple.

When you turn the air purifier on, it draws the surrounding air into the unit.

Not only does it bring in the surrounding room air, but it also brings in all of the pollutants and particles that floating around in the air too, including pet dander, pollen, dust, mold spores, and airborne chemicals.

As the air is sucked through the air purifier, it’s pushed through a series of filters that trap the contaminants.

This process prevents allergy-triggering particles from recirculating back into the room.

Once the air has been cleaned, it’s pumped back into the space for you to breathe in.

To get the best air purifier asthma, you’ll want to make sure that it’s equipped with a True HEPA filter, which we’ll cover next.

What is a True HEPA Filter?

True HEPA filters are a more advanced type of standard HEPA filters.

This means that True HEPA filters can catch and trap more air contaminants.

A True HEPA filter has the potential to remove 99.97% of particles that are 0.3 microns and larger. This covers the vast majority of pollutants that might irritate your lungs and trigger an asthma attack.

Of course, not all air purifiers come with a True HEPA filter.

Some air purifiers come with a standard HEPA filter, which doesn’t collect ultrafine contaminants. 

Lower-grade HEPA filters can only trap particles as small as 2 to 5 microns in size, which is between 500 to 1,500% less efficient.

What About Ionizers?

You might have heard of a type of air purifier called an “ionizer” that can also help reduce air pollutants that might trigger asthma.

While this option is less expensive than other air purifiers on the market, it’s actually not a good choice for people with asthma.

Ionizers can irritate the lungs and respiratory tract of asthmatics and people with COPD or bronchitis.

If you suffer from asthma, running an ionizer could make matters worse and potentially lead to an asthma attack.

So, if you have asthma and are looking for an air purifier, you need to stick to traditional options that come with a True HEPA filter.

If you’re looking for more information about how ionizers work and their potential hazards, we’ve put together an in-depth article that you might find useful here: Are Ionizers Bad for Asthma?

Can Air Purifiers Remove All Contaminants?

The answer to this question is both yes and no.

Air purifiers are designed to remove airborne particles, which means they won’t suck in any particles that are trapped in your furniture, curtains, or carpet.

If you happen to walk across your floor, sit on your furniture, or open your drapes, these acts could cause the particles to be released into the air.

Should that occur, the air purifier can then draw them in and remove them.

Just remember that a True HEPA filter is the only one that can remove the widest range of contaminants from the air in your home.

If you use an air purifier that only comes with a standard HEPA filter, it may not remove all particles that trigger asthma, including ultra-fine dust, pollen, pet dander, and mold spores.

How to Get the Most Help for Your Asthma with an Air Purifier

To ensure that you’re getting the most of one of these best air purifiers for asthma sufferers, it’s in your best interest to use the device in the rooms that you frequent most often.

This might mean getting more than one air purifier so that you can place a separate unit in your living room, bedroom, or basement (if you’re in this area often).

Having air purifiers placed throughout your home is the best way to remove contaminants from the air and keep yourself healthy.

If you don’t want to buy more than one air purifier, or cannot afford it, you can also opt to carry the same air purifier from room to room with you.

However, some air purifiers are quite large, and taking it with you around the house can be cumbersome.

Regardless if you choose to buy one or more air purifiers for your home, you’ll still reduce the number of particles there are to irritate your asthma.

And with fewer airborne particles, the fewer chances you’ll have of experiencing an asthma attack.

Air Purifiers and Asthma

Now you know that answer to the question, “Do air purifiers help with asthma?”

While it’s a definite yes, the trick is to find an air purifier that will work best for you at removing the pollutants that impact your asthma the most.

By finding an air purifier that’s equipped with a True HEPA filter, you’ll no longer have to ask, “Can air purifiers help with asthma?” Because you’ll experience the relief first-hand.

After using an air purifier in your home, it will be easy to tell that the indoor air quality has been improved because you’ll be able to breathe easier and suffer from fewer asthma symptoms.
