Why it matters
The AirDoctor AD5500 is a large-room / whole-floor air purifier that its maker rates for 1,043 sq ft, with a smoke CADR of 556 CFM.
At the usual 4.8 air changes an hour and an 8-foot ceiling, a 1,043-square-foot rating implies about 668 cubic feet of clean air a minute. In a 12-by-15-foot bedroom that would turn the air over roughly 28 times an hour.
Filtration: UltraHEPA. Power draw: 60 watts.
