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.

I have been very happy with the Blueair purifiers (211 Max is the specific model)

That’s what I have too and I have no complaints. Currently in a 1b/1b apartment with 3 cats and have 2 units running 24/7 to help with my bf’s allergies

We love our BlueAir filters. We have a 211i Max for our main floor (overkill) and a 411i max for our upstairs. Would recommend them to anyone!

I second this. My blue runs 24-7. 2 years going strong.

We have 2 BlueAir 211i Max for our living room and upstairs and a 511i Max and humidifier for our kids room. I'm in Salt Lake City, UT where we get heavy pollution in the winter inversions and occasional forest fire smoke in the summer. These purifies make easy work of keeping the air clean and work perfectly with HA. They also have a nice look to them so they aren't as much of an eye sore.
