Are we allowed to talk "smell"?

I have BlueAir 511, Levoit 200, and IKEA Starkvind. The Levoit filter change is much easier than the BlueAir 511

air purifier that can withstand travel??

Can I plug my air purifier into my surge protector

Hey, just wondering if your Blue Pure 511i Max worked when plugged into a power strip. I just got one and it would be best placed in a spot that would require it being plugged into a power strip or surge protector but I can’t get it to work.

Ways to make apartment hvac more allergen friendly?😬

I do already do all that and unfortunately the issue persists :/ I currently have a Blue Pure 511i Max air purifier with the AllergenBlock filter on it, and it did fine in the other two places I’ve lived. I’ve been running it on the highest setting and it still gets filthy and can’t keep up. The onl

Blueair and Dyson air purifier reacting differently to Wildfire smoke in Chicago

I have a Blueair Blue Pure 511i Max and was thinking about returning it as I live in only 480 sq ft and am worried about the ion. I previously have only used Germ Guardian with Hepa and still have one in my bedroom. Do you suggest getting a second one of those or another brand?
