Quiet air purifiers for bedrooms (2026)
For a purifier that runs next to your bed: every model here has a lowest noise level under 22 dB as stated by its maker, and is rated for at least a 200 sq ft room at 4.8 air changes an hour. Ordered by the stated noise level, quietest first, except that the quietest Levoit comes third so the first three are not all one brand. Makers don't say how they measure noise, so treat a 1 dB difference as a tie. Specs checked October 19, 2026.

How to pick between these
- If you want the quietest stated figure → the two Coway Mighty2 models start at 19 and 19.2 dB. Pick the Mighty2 for a bigger room, the Mighty2 Mini for a standard bedroom.
- If you want to control it from your phone → choose a Levoit: the Eleva 300X and the Vital Pet Pro both list the VeSync app.
- If you want a filter the maker calls True HEPA → none of these does; the quietest True HEPA model we catalogued is the Winix C610 at 22 dB; choose "Yes, True HEPA" in the finder to see it with the other Winix models.
- If odors matter → the Mighty2, Mighty2 Mini, Eleva 300X and Vital Pet Pro state a carbon filter; the Airmega 150 doesn't say.
