The best air purifier for asthma is, hands down, will be made by Blueair. Blueair’s air purifiers are the best at removing particles, allergens, and dust from the air before they cause your asthma to flare up.
Why Blueair? Well, Blueair is a longtime manufacturer of air purifiers and they are really good at it. Few air purifiers are as good at removing particles from the air as thoroughly or as quickly as the ones made by Blueair. For asthma sufferers, getting rid of particles that could cause an asthma attack.
Our favorite air purifiers that are made by Blueair are from their Blue series. (You can read up another article that we wrote on why the Blueair Blue Series is our favorite here.) These air purifiers are so good that you’ll see them recommended by just about everyone.
The Blue series from Blueair comes in four sizes which makes them even more appealing. They have air purifiers that are smaller (and cheaper) that are for bedrooms, and larger ones for larger and larger rooms. Why is that important? Well, think of it like car buying–if you’re just looking for a ride for yourself, then you can pick up something small and cheap that will get you to and from work. On the other hand, if you’re looking for a bigger car for a bigger family, you’ll probably end up spending more.
Before we go on and tell you what rooms you might need your air purifier in for your asthma, or your child’s asthma, we’ll quickly share how air purifiers help with asthma in general and what you should look for in an air purifier for asthma.
How Can Air Purifiers Help with Asthma?
Asthma attacks are dangerous and air filters can help to lower your risk of having one. It doesn’t matter where you live, good quality air can help to reduce your risk of an asthma attack. Good air can even help people who don’t have asthma too. The best air purifiers for asthma will take care of smoke, allergens, and airborne particles that are known to cause asthma attacks.
WebMD reports that air purifiers can help with asthma in this article and they are very much right. However, they do point out that air purifiers don’t magically make the air absolutely spotless. These machines don’t instantly filter out every particle in the air, but they do clean out most of them in due time (usually well within an hour and oftentimes several times an hour).
As WebMD also reports, air purifier’s can’t take care of “local disturbances” where particles are sent airborne when you strike an object that has something like dust on it. Ideally, a cleaning regiment that includes vacuuming weekly at the very least will lessen the risk of that.
We must point out that air purifiers will only help to reduce your risk of an asthma attack when you are within their coverage area and we hope that our references to WebMD’s post illustrates that.
Air purifiers for asthma will have things called HEPA filters that filter out 99.97% of the particles in the air. HEPA filters are ideal for any asthma sufferer and should be seen as the bare minimum for anyone who is buying an air purifier to help with their asthma or a loved one’s asthma.
Air purifiers with HEPA filters will filter the air in whatever room you put them in by pulling the room’s air through the filter (or filters) that it has. Once the air is sent through the machine, it will be shot back out and you’ll be able to breathe easy with the machine running.
There are other filters out there that will clean the air even more, but those come with an added cost. Some can take care of smoke, some germs, and some can even take care of harmful gasses like VOCs! At the end of the day, people who suffer from asthma will likely benefit the most from an air purifier that cleans the most things out of the air.
The Three Things to Look for in an Air Purifier for Asthma
Ok, so I think I might have you excited with my last paragraph. I know I got excited when I found out that there were so many things that could help with asthma. I mean, come on, there’s really an air purifier that can kill germs, take care of smoke, dust, allergens, and even odors and VOCs! That’s a ton of stuff!
But, how can one air purifier do all of that?
The answer? Filters. Three filters, in fact. (Imagine that, three filters to take care of three problems!)
So, the first thing to look for in an air purifier for asthma is a HEPA filter. I already mentioned that a bit, but I’ll talk a little more about it now. HEPA filters are the minimum requirement in our book when you’re looking for an air purifier for your asthma.
HEPA filters take care of microscopic particles that are so small that you can’t even see them. Those same particles are often the very same ones that can cause your asthma attacks. In addition to taking care of these microscopic particles, HEPA filters clean 99.97% of the overall particles in your air, which is pretty stinking good!
Better HEPA filters are being designed and upgraded constantly and True HEPA filters are the evolution up from the traditional HEPA filter. The Blueair air purifier that we are recommending has a HEPA filter, which is one of the reasons why we recommend it.
Activated Carbon Filter
Activated carbon filters take care of odors, smoke, and VOCs. VOCs are known to be extra problematic for people with asthma, so an activated carbon filter is an absolute must. Smoke is another bane to the existence of asthma sufferers, which makes activated charcoal filters all the more valuable.
The Blueair air purifiers that we recommended today all have activated charcoal filters, so they’ll be a great help for you and your asthma.
Airborne pathogens are extra dangerous for asthma sufferers. Not only can these pathogens attack your already sensitive lungs, but these germs are known to hitch rides on particles that can also cause asthma attacks.
Air sanitizers kill the germs and the HEPA filters that these units often come with will take care of the particles they ride on. Something else that’s cool is that some HEPA filters are supposed to be antibacterial on their own and the Blueair air purifier that we’re recommending today is one of those.
While this is actually a fourth thing, I’m including it because while it isn’t a requirement for air purifiers for asthma, it’s still a good thing to have and can save you money in the long run. The Blueair air purifier that I’ve recommended today has a washable exterior pre-filter that you can get different colors of to customize your machine with.
What Room Should I Have My Air Purifier in if I Have Asthma?
If you or your child have asthma, then you know just how bad asthma is. You know how different life is because you have to avoid all the things that might cause a flare-up.
Odds are, you might be thinking about buying an air purifier for every single room in your home since air purifiers are so good for asthma.
But it might be a lot more affordable to rethink that idea. Instead, focus on what rooms the asthma sufferer in your home spends most of their time in. They’ll probably spend a lot more time in their bedrooms (you sleep about eight hours a day, so that’s a lot of breathing) and in your home’s living area (like a living room, dining room, and kitchen).
Additionally, you might want to consider sticking an air purifier near the entrances of your home where allergens might enter from the outside world. Getting a good air filter for your home’s furnace that will take care of allergens could also help to keep particles out of the air you breathe before they can get into your home.
Ok, so now you know what you can do to clean your home’s air and what rooms you might need an air purifier in. Now what?
Now you look for air purifiers for the rooms you need. There are lots of options to choose from for every size room, and that’s one of the reasons why we recommend the Blueair Blue line of air purifiers for asthma. These units really are amazing at removing allergens, smoke, odors, and even airborne germs and they come in different sizes.

Ok, but what if I haven’t sold you on air purifiers enough just yet for you to buy a unit that’s as expensive as these?
Well, I have good news, there are lots of cheaper air purifiers out there too. These are not going to be as good as the Blueair air purifiers for asthma, but they’ll give you a taste of what good, clean air can do for your asthma.

Frequently Asked Questions
Can HEPA Filters Help with Odors?
Yes, HEPA filters can help with odors and even smoke, to a limited extent. However, if you re concerned about odors and smoke, then an activated carbon filter is the better option for you.
Can an Air Purifier Help me with My Pet Allergies?
Air purifiers are great at removing pet hair and allergens from the air. That being said, they can’t clean your carpet, so any allergens that are in the carpet will remain there.
Do Water-Based Air Purifiers Help with Asthma?
Yes, but they won’t get the air as clean as an air purifier with a HEPA filter. If you’ve got asthma, then an air purifier with a HEPA filter should be your first option and, since they can be quite affordable, there’s no reason to go for a water air revitalizer.
