How to choose
Read coverage as the maker's figure
Coverage is the maker's own figure for a stated air-change rate, so compare it against your room's floor area. The Nuwave is rated for up to 3,210 sq ft, the AEOCKY for up to 2,300 sq ft, the WINIX for up to 1,968 sq ft, the Shark for up to 1,650 sq ft and the DREO for up to 1,176 sq ft. These figures come from the makers, not from a shared test, so a bigger number means a bigger stated room, not a stronger filter. Match the stated coverage to your space before you compare anything else.
CADR, filters and modes
CADR measures how much filtered air a purifier delivers, so it separates machines with similar coverage. The AEOCKY lists 240 CADR in Turbo mode and the DREO lists 158 CFM CADR, while the other picks state coverage without a CADR figure. Modes matter too: Auto modes adjust fan speed to sensor readings, while Sleep modes dim the display and lower fan speed.
Noise, weight and placement
Noise and weight decide where a purifier can live. The Nuwave lists 18 dB, the WINIX 23.5 dB and the DREO 24 dB, so compare the stated decibel figures if the unit will run near seating or a desk. Weight is the other check: the AEOCKY weighs 5.9 lb, the DREO 6.9 lb, the WINIX 8.4 lb, the Shark 13.6 lb and the Nuwave 28.6 lb. A heavier unit suits a fixed spot, while a lighter one moves between rooms with less effort. Check the footprint too: the Nuwave measures 14.19 by 14.19 by 26.25 inches, the tallest here.
