What is the Best Air Purifier for Asthma?

Many people want to know, “What is the best air purifier for asthma?”

And if you have asthma, this is an extremely important question to ask yourself.

In order to be as healthy as possible, you need a high-quality machine that’s capable of purifying indoor air from the most contaminants that cause asthma symptoms and attacks.

The good news is that we’re going to help take the guesswork out of which is the best type of air purifier to get and why it’s a great choice for asthmatics.

So, read on.

First, Getting the Right Type of Air Purifier

When you’re looking for the best air purifier for asthma, the short answer is that you want one with a HEPA filter.

However, the type of HEPA filter the machine uses is crucial to how well it will perform for asthma standards.

The truth is that there are actually three types of HEPA filters available on air purifiers.

HEPA stands for High-Efficiency Particulate Air, and this type of filter is considered to be the gold standard for helping alleviate asthma and allergy triggers like dust, pet dander, pollen, and even mold spores.

When you’re comparing air cleaning machines, you’ll find that you have a choice between:

  • True HEPA filter
  • HEPA-type filter
  • and a HEPA-grade filter

For asthma sufferers, you always want to go with the True HEPA filter because this filter can trap and lock in up to 99.97 percent of all airborne contaminants of the smallest size (0.3 microns).

To help you narrow down your search for such a device, we’ve put together this free best asthma air purifier guide that lists the two best products you can get.

The secret to a True HEPA filter is the dense filter design. They’re far denser in design than HEPA-type or HEPA-grade filters.

This design allows fewer contaminants to get through the filter and recirculate back out into your indoor air.

HEPA-type filters and HEPA-grade filters also work better than traditional filters, but they can’t necessarily trap and lock as many asthma-inducing contaminants.

Their limit is 2-3 microns or larger, which is significantly less than what a True HEPA filter can capture.

If you have asthma, you may have already done some searching on the topic of does fresh air help asthma and know that it’s important to remove as many possible triggers or irritants out of your home’s indoor air.

Even the slightest increase in any one kind can wreak havoc on your breathing.

Therefore, always get an air purifier that uses the True HEPA filter type.

Second, How to Tell if Your Air Purifier Has a True HEPA Filter

Most air purifiers will advertise which type of filtration system they use and whether it comes with a HEPA-type, HEPA-grade, or True HEPA filter.

If an air cleaning device you’re interested in doesn’t advertise the fact that it has a True HEPA filter, then you can assume that it uses a lower quality version, and to stay away from it.

No manufacturer will omit the fact that it uses a True HEPA filter because it is the gold standard for air purifying machines

Another thing to keep in mind is that a good True HEPA filter should also last for a year or two, depending on its use.

So if you find that an air cleaner with this filter type is slightly more expensive than a competitor using a lower grade filter, understand that you will get more life out of the higher quality True HEPA type.

Finally, when you’re searching for an asthma air purifier you may come across products that are labeled as “ionizers” and if you do, you should avoid them.

We have another post that talks all about what is the difference between an air purifier and ionizer, but for now just know that ionizers can actually make your asthma worse so it’s best to stick to True HEPA air cleaners.

The Bottom Line

Asthma is a serious medical condition, and you want to have the best possible air when you’re indoors.

So, what is the best air purifier for asthma? Now you know that it’s one that uses a True HEPA filter, and why.

When it comes to cleaning your indoor air, you simply can’t beat the quality that you get with this type of filter system.

When you go to buy your air purifier, make sure that it says True HEPA on the packaging and you should start to notice a difference in how well you can breathe inside your home.
