How to choose
Read coverage as the maker's figure
Coverage figures here are the makers' own ratings, not a promise for every room shape. The SwitchBot is rated for up to 3,620 sq ft, the Afloia for up to 1,076 sq ft, the DREO for up to 856 sq ft and the GoveeLife for up to 376 sq ft. Compare the rating against your room's floor area, and remember that a higher CADR moves air faster: the Afloia lists 140 CFM and the DREO lists 115 CFM.
Alexa control and app control differ
Every pick here works with Alexa, but the path differs. The GoveeLife and Afloia take Alexa voice commands directly, the SwitchBot works through Matter, and the DREO pairs Alexa with Google Assistant and its app. All four also offer app control, so decide if you want voice only, app only, or both before you buy.
Filters, noise and timers
Filter type decides what you replace. The GoveeLife, SwitchBot and DREO use HEPA filters, while the Afloia uses a 3-stage filter, and the SwitchBot pre-filter washes. For noise, the SwitchBot is 20 dB, the Afloia 22 dB, and the GoveeLife and DREO 24 dB each. All four have timers, so set one for sleep hours or for running the unit before you get home.
