Why it matters
The AirDoctor AD2000 is a HEPA room unit air purifier that its maker rates for 305 sq ft, with a smoke CADR of 162 CFM.
At the usual 4.8 air changes an hour and an 8-foot ceiling, a 305-square-foot rating implies about 195 cubic feet of clean air a minute. In a 12-by-15-foot bedroom that would turn the air over roughly 8 times an hour.
Filtration: UltraHEPA. Quietest setting, per the maker: 30 dB. Power draw: 11 watts.
Price-wise it sat in the dearest third of the 74 hepa room unit models we cover when we checked; the button shows today's price.
