These blueair 411 are great for bedrooms.

We have [BlueAir](https://share.google/fIAJcdzxHkRDEiVpp) filters in our house because we are all allergy sufferers. They work amazingly well, are reasonably quiet, and are mechanically pretty simple - no issues at all in 3 years of running them pretty much continuously. You do have to replace the filters, but not as often as I expected. They make several sizes, but for that size room you could get their smallest one, [the 511](https://share.google/KgFD7DARpe0A4mnEA), which is $100. They work really well on wildfire smoke.

Unfortunatly, i had at Blueair 411 formabout 5 years in the bedroom. It just stopped working. So I replaced it with the newer 511

Blue air. My wife suffers of airborne allergies, and these air purifiers practically eliminated her allergy episodes at home. We know they worked since a couple of times we have tried generic filter replacements and my wife allergies were back, but disappear again as soon as we bought the original brand name filter replacement.

It’s honestly so good! I initially started with the 511, 5 years ago and recently just upgraded to the blue signature (during Black Friday) which is the prettiest out of the bunch! lol I’d absolutely get the 311 for our other rooms— gotta wait for another sale tho lol
