We have a Levoit 300 and a BlueAIR guy with the fabric outer filter (washable) and like both of them a lot. Very, very quiet and filters last 6 months.
We also have a Coway Airmega for the big room, also great!
Last summer @jeremydnichols.bsky.social got COVID & we were trying to shield me while also not being able to keep windows open due to wildfire smoke. Air filters galore!
Possibly more info than you need: Some of them have little indicator lights on top that turn red when they detect a problem, then the fan speeds up, then they turn back to blue/white when the problem is addressed. Great for cooking smells, etc. right?
But also means there are machines in my house that can instantly detect whenever the cats poop from several rooms away, especially since Henrietta refuses to bury anything. A bonus feature!
