If you suffer from asthma – or you have a loved one who does – you know that it’s a lot more than just an uncomfortable breathing condition: it’s a serious, potentially deadly, lung disease which deserves a lot more attention than simply keeping an inhaler handy nearby.

There are a variety of different triggers which can cause an asthma attack, including upper respiratory infections, tobacco smoke, and excessive exercise. But for many sufferers, the number one cause of their asthma symptoms is something that they can’t see, smell, or feel: the pollen, pet dander, mold spores, and dust mites which fill up the air in their home.

Thankfully, modern air purifiers are able to remove up to 99.97% of all airborne pollutants down to just 0.3 microns in size. Any for anyone who regularly falls victim to attacks, investing in the best air purifier for asthma for their budget and spatial needs can make a huge different in keeping future symptoms mild and at bay.

Best Air Purifier for Asthma 2017?

All three of the units on our list of top air purifiers work well for asthma in their own capacity and price classes. But for the buyer who’s determined to invest in the best air purifier for asthma out there, there’s no denying the power and performance of the Coway AP-1512HH.

While the Coway may not have capacity of a full-home air cleaner, it’s able to purify spaces up to 326 square feet better than models which cost twice as much. In our experts’ opinion, the best way to clean the air in larger spaces is simply to invest in more than one compact purifier. Doing so can effectively cleanse the polluted air in your home much more effective and cheaply than purchasing a whole-house unit which could run more than a thousand dollars by itself.

How Do Air Purifiers for Asthma Work?

In the United States alone, more than 25 million people suffer from asthma on a daily basis.

Asthma attacks are scary, both for the sufferer and their loved ones, and while we can’t always prevent attacks from occurring, there are some things we can do to less their frequency and severity.

That’s because the air in our homes is often more polluted than the air in large cities. It may sound odd, but it’s true: because of how effective modern building practices are, most homes simply don’t get the fresh air flow and circulation needed to keep harmful pollutants from accumulating.

That’s where air purifiers fit in.

These cleaners work by sucking dirty air into the unit and across a finely-slotted filtration medium. By passing air through a filter, modern purifiers are able to trap up to 99.97% of all pollutants while allowing the filtered, clean air to flow out the other side of the appliance.

Not all air purifiers are equal however – some are able to handle filtering larger amounts of air than others, while some simply don’t have the quality filters needed to truly remove the majority of dangerous pollutants.

That’s why you should only consider an air purifier for asthma which features a high CADR and a built-in PureHEPA or TrueHEPA filter for optimal performance.

What Does Clean Air Delivery Rate Mean?

When you’re shopping for the best air purifier for asthma, you’re positively going to come by a few industry-specific terms that you may not be familiar with. CADR is likely going to be one of them.

CADR stands for Clean Air Delivery Rate, and it’s a measure of how much air a specific unit can process every sixty seconds.

CADR is measured in cubic feet per minute. For example, an air purifier with a CADR of 250 would be able to process and filter 250 cubic feet of air every minute. Essentially, a unit with a larger CADR would be able to keep a bigger portion of your home purified.

What’s the Big Deal about HEPA Filters?

While air purifiers a decade ago were just beginning to use HEPA filters as a standard filter, you’ll be hard-pressed to find a modern unit which doesn’t use HEPA technology today. That’s because the two most prominent types: PureHEPA and TrueHEPA, both remove up to 99.97% of airborne particles down to just 0.3 microns in size.

In short, if you’re using a HEPA filter (which everyone with an air purifier should be), you can expect to be breathing the highest quality air possible.

Do I Really Need an Air Purifier for Asthma?

If you or someone who you live with suffers from asthma, even if it’s only the occasional attack, yes – you do need an air purifier. That’s because even the most infrequent asthma attacks can be very serious matters – even potentially deadly.

For anyone who lives with asthma, having an air purifier is much more than just breathing in filtered air: it’s keeping out all of the dangerous dust, pollen, danger, and mold which could increase the frequency of your attacks and severely worsen the symptoms.

And if you’ve ever suffered through a serious attack – or watched someone who has – you know that just preventing a single instance far outweighs the relatively minor cost of investing in the best air purifier for asthma that you can afford.
