6 Best Air Purifiers for Mold in 2022, According to Experts and Reviews - Health.com

Filters: Washable pre-filter, activated carbon filter, and HEPASilent filter
Room Size: 540 square feet

What you'll love: Even though it doesn't have a True HEPA filter like many others on this list, the Blueair air purifier uses its own method of filtration called HEPASilent technology, which claims to catch particles as small as 0.1 microns. The brand says this filtration method is comparable (and perhaps more efficient) than traditional HEPA filters. The first layer of defense is the washable fabric pre-filter that catches large particles, while the activated carbon layer is what traps odors (whether from mold, cooking, or pets). The air purifier can be placed nearly anywhere in the room because it filters from all directions, and it only has one button so it's very easy to use.

Keep in mind: Some reviewers experienced unpleasant, plastic-like odors during the first few days of use. "That smell went away after a couple days, so don't let that keep you from trying this unit," one person wrote. 

What reviewers are saying: "I was having great difficulty breathing after a then-unknown mold exposure," wrote a customer. "Between the time the mold was discovered and the time it took to get a contractor out to take care of it, I could not breathe indoors… This purifier allowed me to breathe almost immediately."
