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

Which air purifier is the quietest at level I (not sleep mode) for ~380 sqft family/home theater room?
Thanks for sharing the alien brand. So, it can be done…I got recently a Blueair 511 max for a smaller room and it is silent on level I.

air purifier that can withstand travel??
I've flown repeatedly with my BlueAir 511 in checked luggage. It's comparable to a Levoit Core 300. Maybe your luggage is the problem?

Please help me not waste money
Since you want to purify your whole 1300sq ft living space, do you have forced air heat and AC? If so, you can get a MERV 8 furnace filter that will work very well. If you don’t have forced air hvac, the box fan CR filter is the next best thing for the large living space. Otherwise for bedrooms, I r

Apartment smells like weed
Going through this as well. I went to Best Buy and got 2 Blueair 511i Max air purifiers. Took like 30 minutes and the smell is 98% gone. It's coming from our bathroom. It shares a vent and fan with them. I figured that our because the closet that shares a wall with them and is right next to the bath

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.

Thank you for this post! I purchased a Blueair Blue Pure 511i Max on Friday after much deliberation.

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?
