How to choose
Match coverage to the home
Coverage sets the room size a purifier serves, and the maker figure is the number to compare. The Blueair is rated for up to 3,235 sq ft by the maker, the Bmasse for up to 3,000 sq ft, the PuroAir for up to 2,000 sq ft, the Winix for up to 1,968 sq ft, and the FreAire for up to 1,800 sq ft. Match the coverage figure to the size of the home before comparing noise and filter layers.
Compare noise and sleep modes
Noise is given in dB, and sleep mode is the quiet setting for bedrooms. The Bmasse runs at 15 dB in sleep mode, the FreAire at 20 dB in sleep mode, the Winix at 23.5 dB, the Blueair at 23 dB, and the PuroAir at 35 dB. Compare the dB figure with where the purifier will run.
Check filters, sensors, and upkeep
Filter layers set what a purifier holds, and washable pre-filters extend the main filter. The Bmasse and Blueair have washable pre-filters, the Winix has True HEPA sets, and the PuroAir and FreAire have 3-layer filters. Sensors also differ: the Winix, Bmasse, Blueair, PuroAir, and FreAire each use a sensor or display to track air quality. Check filter types before you pick.
