How to choose
Match the maker rating to the room
Start with the coverage each maker gives. The Shark is rated for up to 250 sq ft by the maker, the SILVERONYX and the Coway for 500 sq ft, the Honeywell for 530 sq ft and the GoveeLife for 1,162 sq ft. Measure the room first, then pick a rating at or above that figure.
What CADR and noise mean
CADR measures how much air a purifier moves through its filters. Only the GoveeLife gives a CADR here, at 150 CFM. Noise is given in decibels: the Coway gives 18 dB in Sleep Mode, the Honeywell gives 20.81 dB, the GoveeLife gives 24 dB, the SILVERONYX gives 25 dB and the Shark gives 53.3 dB. Compare those figures against the room where the unit will run.
Filters, modes and upkeep
A washable screen or pre-filter cuts replacement work: the Shark has a washable debris screen and the GoveeLife has a detachable pre-filter. Modes differ: the GoveeLife adds Turbo Mode, the Honeywell adds AQSense Auto Mode and the Coway adds Auto Mode with an AQI monitor. Check the filter change indicator on the Honeywell and the Coway before you buy.
