Keeps allergens down
Love this airfilter. It filters for my allergies and the wildfire smoke particles and makes it easier to breathe.

BlueAir kit works well
I have two, a big 211i for the open plan great room and a little Signature Series for my bedroom. The BlueAir filters hold their own keeping particulate concentration in the ones even when wildfire smoke is heavy. They're also effective against pollen. I have filter subscriptions and change the filters on each every 6 months. Subscription notifications are timely. The HEPA filters provided are well made and easily changed.

Oustanding Air Filter
Great unit, easy to use and program. As disgusting as it sounds, it is great to see all of the dirty air particles it is collecting that otherwise would have been collecting in my lungs.

Replaced filter
This filter did a beautiful job when we were suffering from all the smoke from the Canadian fires.

The best of the air filters.
I have 2 Blue Pure 211 I Max air filters, one in the living room & one in the master bed room. They run full time and really clean the air. I also like the fact that they have the washable pre-filters, as that saves the main, expensive filters from filling up with dust & dirt, prematurely.

I love my Blueair Blue Pure
This is my second purchase of a Blueair product and I love both of them. Both are well designed and perform very well.

Air Purifier (Large)
I love this idea and all the various good effects it has had on my home, but the directions are difficult to read and understand. I find it difficult to read such fine print. Other than that, the unite works and is doing a good job.

I love my Blue Pure 211i Max!
On July 2, my 21 year old refrigerator decided to die a smokey death. Smoke drifted from my kitchen to the living room where my Blue Pure was situated. After unplugging the refrigerator, Blue Pure cleared the room of smoke and odor within 2 hours. Great job Blue Pure!

Review
Can’t make the automatic sensor work, even after trying the online fixes suggested. Filter box arrived damaged.

No Change
We have two Great Pyrenees dogs. I bought this from reading about how it is supposed to help with both dog smell and dog hair; along with other house hold orders. I was not expecting a ton of help with dog hair, but expected some. I have not noticed any difference with any of it. It barely comes on in auto mode. I usually turn on the fan myself. I would not buy this again.

Older Purifer Works Better
I bought this new Pure 211+ purifier as there were no options to buy the older 211 model. Although they are the same size, and I read great reviews, this new one does NOT filter the air as my older model does, and it is filtering a significantly smaller room/area. The air does not smell fresh nor clean. It smells worse even when I come home after being closed up all day. From Day 1, the room consistently has an almost chemical/musty/mildewy smell that does NOT go away even with the windows open, and has been steadily getting worse the past 1.5 months.

Simple and clean design
So far I’m a fan of the design, it blends really well in my home, it’s perfectly quiet, and I love the data and information available in the app. Haven’t had to change a filter so we’ll see how easy cleaning and maintaining will be but so far so good.

Awesome! Air filter
These things are the best. I got two for my house and they are fabulous. The air is so much cleaner. We don’t sneeze like we did from allergies. I highly recommend these.

Filter change
When I changed the filter, I could tell a definite difference between the old and the new. That's proof positive that the unit works!
