This way it quietly works without you even having to pay attention to it. When we first plugged it in, it said the air quality in our room was between 20-30, and it went straight into turbo drive pushing new filtered air into our space. Within minutes, our air quality was down to 5, and I was impressed." — Krista Jones, former editor, Shopping

I set this air purifier up in that room since the air quality was so poor — and I was amazed by how clean the air was after just one night of use. The air purifier claims to capture 99.999 percent of nano-sized particles down to 0.01 microns (most bacteria, mold, and allergens included) and I can say it's actually made a difference for me during allergy season and beyond.
