best HEPA air purifiers 2020


If you live in a large city, have pets, or struggle with allergies, there’s a good chance that you could use an air purifier. Air purifiers use filters and a fan to capture pollutants and push clean air back into your home, allowing you to breathe easier — and better.

According to Rachel Rothman, the Chief Technologist & Director of Engineering of the Good Housekeeping Institute, a HEPA (High Efficiency Particulate Air) filter is a must-have feature in an air purifier. “HEPA filters can capture variously sized particles within their multilayered netting,” Rothman says, which means that they can remove “ultra fine airborne particles like dust, dander, pollen, and mold.”

In addition to a True HEPA filter, Rothman also recommends paying attention to the CADR (clean-air delivery rate) and looking for an AHAM (Association of Home Appliance Manufacturers) Verified mark, both of which will help you choose an effective and safe air purifier for your home.

It’s also important to think about the size of your space when shopping for an air purifier. A device that’s too small won’t be able to perform what it’s been designed to do in a bigger room. Plus, you have to consider filters, too, which need replacing to work properly. Affordable air purifiers might actually be more expensive in the long run if their filters need to be replaced frequently.

We did the research so that you can breathe a little easier. Check out the best air purifiers for every budget below.
