Wonderful overall... a must have. Don't hesitate and buy it! Great quality, keeps air fresh

Best air purifier, it automatically adjust according to the air quality. I have 3 of them a one large for living room, medium size for bedroom and a small for home office.

The Blue Air 211 air purifier works extremely well. I was somewhat unsure of its ability to capture diesel exhaust, but when that's outside of my residence, I've never smelled it inside. The filters are not cheap, but my health is worth every penny.

Really enjoy these filters. You can always see how well they work and we also breathe better right after changing the filter. Notice the difference right away.

Our Blue Pure 211+ air purifier let us know it was time to replace the filter. The Blueair Replacement Filter for our Blue Pure 211+ Auto Air Purifier was very easy to replace and works as expected.

My BlueAir from BestBuy was one of the smartest purchases I’ve ever made. When I needed to replace the filter, BestBuy is the first place I looked. I compared pricing & even tho this air purifier is almost priceless to me, I went with the lowest price & purchased from BestBuy.

These filters aren't cheap, but they are worth it for us. You can probably find cheaper alternatives, but this is one situation where I do think you get what you pay for.

BlueAir with this filter is a stellar air cleaner. Minimizes overnight congestion and keeps dust particles out of the air so I breathe easier.

Best air filter for 211+ Atuto ever. Be careful because they make one for the 211+ that is incompatible with the 211+ Auto; As long as its a 211+ Auto your air will be nice and crisp!

I love my Blueair air purifiers. I keep them clean and check its progress often, definitely works!

I've had this air purifier for years and the replacement filters work great. Keeps the air fresh and not smelling like dog.

Have the blueair purifier and am so glad I got this model. Jusr bought a replacement filter for it and got it so fast. Just wish they were not so expensive but no matter where you buy them they are not cheap.

The filter is a bit on the expensive side, but it's worth it. I keep the Blueair on all the time and you can certainly tell the difference in the air's quality

As good as a filter can be. Seems like it works much better then cheaper replacement filters you could get. Nice that it just slides right in

These seem to work well but it’s cheaper to get online, I got this one because I had rewards, seem to work the same.

Blue air really works great to purify air and dust in the house.

This is a great filter that I will continue to order when time to replace the old filter.

Love my air filter. Like the fact it has a washable cloth as a pre filter. The new filters last about a year for me.

This filter works great. Easy to install and does the job. My brother is allergic to cats and cannot come inside our house without this filter on. No more sneezing attacks while filter is running.

I have this air purifier and needed a new filter. Easy to replace and works great. Only con is the price but this is how much this filter is everywhere if you don’t want generic.
