Blue 211+ Auto

I have a blue air one and it’s dumb but you can put it on a smart outlet because it remembers the previous settings.

I am a Blueair girly for 5 years now. I purchased mine due to days of research and consumer reports back in 2020. I keep mine on high since it is a nice white noise sound for my dogs (otherwise they bark at any little noise at night). The high setting is also where you find most of the benefits of cleaning the air in the room. If I do not have mine on, I can smell my dogs and everything feels dirty. I have two 211+ models.

I have two Blueair purifiers that can get very loud on the highest setting--the 211+ Auto and the Classic 500/600. The latter one was discontinued and the 211+ can still be bought at Amazon, but not at Blueair. Finding OEM filters is no problem for either. You might also consider a sound machine that has fan noises and can get very loud. The loudest and best one I have found is the one below. It has 10 fan sounds and 10 white noise sounds, and the only machine loud enough for me. [https://www.lectrofan.com/collections/lectrofan](https://www.lectrofan.com/collections/lectrofan)

I had a couple of Winix 5500? units and now have a BlueAir 211+. I tend to open the balcony door when I cook so most of the smell vents out, and I live in a place that's not too dusty, so it works well in reducing dust on furniture. Unfortunately my place has wall to wall carpets. Is it worth it? I don't know. Less dust and obviously the dust stuck in the machine is dust not on the furniture, but is it reduced enough to where I'd buy it again? Not sure. My place is 988 sqf, so pretty small too. A few things to keep in mind; A lot of them have no real testing done, just bloggers who claim it does something. Filters can be expensive. They usually need to run on high to reach their CADR, and on high they are usually noisy, so I can only run mine on low or medium in the other room. No chance using it in the bedroom if I'm in there.

I have a Molekule and it’s sitting stored. The replacement filters are expensive as hell, and I find my BlueAir (the 211+) and Coways (Airmega 250 and 150) to be better. The latter aren’t “smart,” (although I think you have that option now), but I have them plugged in with smart plugs and I like that the Coways signal when the air quality changes like a basic air quality monitor would.
