Exact same here. It was so good that we got 3. The filters are a little pricy but rock solid design and very reliable.

Blueair 211+ non auto. Been using them for seven years and still going strong. They have truly changed my life for the better.

I second the Blueair purifiers. I have the 211+ non auto in my living room and the smaller versions in my bedrooms. I've had the 211+ running for about ten years and still going strong. The smaller ones I had to replace recently. I got the table top Mini Max through Costco in a 2-pack and I regret that size. I'll get the smaller standing 411 ones again next time.

It's not that there is no truth out there, it's just that air purifiers work differently for individuals, depending on their living conditions and sinus/ allergy problems. I'm a big fan of BlueAir, have two older model classics and two older model 211+. I would recommend you get one Classic Pro CP7i and try it out in one room or the basement. It "rapidly cleans 580 ft² in 12.5 minutes 1,400 ft² in 30 minutes, and 2,800 ft² in 1 hour". It's on sale right now at the BlueAir website for $560, marked down from $700. See if that works for you. If not, sorry I suggested it, but as I said, air purifiers work differently for different people.

I have one and think it is worth $50. I got it at Blueair and it was on sale for $300 or so off. It's a very expensive air purifier and three filters are need. If you want odor control, too, you must get the [Classic 500/600 Series DualProtection Filter](https://www.blueair.com/products/500-600-series-dualprotection), as opposed to the filters that just clean the room. They range from $120-150 for three, depending on where you buy them online. The Blueair website even has a subscription plan where you get a discount for subscribing. I'm using it in a foyer which is connected to a living room and dining room, and it works fine. The foyer is right off the breakfast nook and kitchen, and it does an excellent job eliminating cooking smells that drift into the foyer and can travel upstairs. The first two speeds are quiet, but the third highest speed is very, very loud. I also have the Blueair 211+ and 211 Auto in other rooms and really like them, too. If I need air purifiers in the future, I will always buy Blueair.

r/bernesemountaindogsAnyone use air purifiers?

We have 3 air purifiers (one in the main space, one in my bedroom, one in the basement)- necessary when you have a Berner and 6 cats lol. The big main spaces ones are blueair blue 211+s- they're amazing, the covers are machine washable and they're super quiet. My room one is just a little one from ikea lol- also works great, but is definitely for a small room only.

r/vancouverWhat air purifiers are best for forest fire smoke? In a 400sq ft room?
7 months ago

I use a blue air 211+ filter and love it. For some reason it also feels like the air cools down, but I know that's just because it's moving the air around the room. I've had mine for 4 years now? Replacement filters are a bit pricey, but it really helps the air in the old building I live in.

r/homeownersThe Best Air Purifier for Home to Buy now? Do you find the air in your house actually better since you started using it?
5 months ago

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.

r/smarthomeAnyone have a air purifier?
about 1 month ago

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.

r/BuyItForLifeThe Best Air Purifier on the Market? Recommendation?

Coway AP-1512HH and Blueair 211+ are top picks, quiet, powerful, and long-lasting. Great balance of performance and value.
