Customer Ratings & Reviews

The Blueair Blue Pure 311i is a very nice unit. At just around 7 lbs it’s light enough to carry around the home for use in various rooms, and quiet enough to use in bedroom.

I researched before getting my air purifier and this one came up the best for pricing/budget and how much space i wanted it to cover. So glad i got it. I would recommend it

Finally crisp and clean air in New York. This is my third air purifier and my favorite . Reasonably priced with an aesthetically beautiful exterior . I love the intuitive app as well.

This is an excellent air cleaner in operation and design. I have 2 other Blue Air Cleaners. In winter the house is closed and more difficult to get fresh, clean air into the rooms and these help a great deal. My allergies are much less noticed. This particular unit responds automatically to the amount of air pollution it senses with a variable speed fan but can also be set manually for 3 other speeds.

It works great and having the app to be able to control it is amazing. Same with the filter life on the app to remind me when to change it. I would recommend thing product and buy another too

What a change this has made for our open spaces downstairs! No more dust particles floating around the kitchen.

I am very happy with this air purifier, though when I plugged it in for the first time it registered blue. This surprised me since it meant excellent air quality and I was purchasing it because I thought my home’s air quality wasn’t as good as it could be. But one day I sprayed a fragrance mist near the device and the indicator light turned green! I also noticed it turning green when I was folding a blanket that needed laundering, so it is definitely reacting to pollutants and cleaning them up quickly.

A fantastic purchase. I am still on the 1st filter almost 2 years later. Not available as new anymore. Newer models are available.

Love this product! Very quiet and this is important because it is in the living room. Have really noticed a difference in the dust and kitchen smells since we started using it. Would absolutely recommend it!

I love these air purifiers and being able to use with an app on my phone. I know exactly the quality of air in my home at all times. Filters will not be as high as others and I checked reviews before my purchase of 3.

Quiet,efficient, and good looking. Auto function is great for cooking and woodstove. Noticeable difference in air quality.

Bought due to Canada fire smoke remnants in Chicago suburbs this Summer. Loaned it to our kids to use in our grandson’s room, was a good feeling to know his developing lungs could breathe filtered air. Enjoy controlling on/off/status with my iPhone app.

Amazing! Used to have the bad allergies and now sleeping much better. Great for pets.

It runs very quietly. It also informs you of when the air quality is bad and when it is ready to be cleaned. Also cleaning is easy.

We own several air purifiers as I'm an allergy / asthma patient. Lots of nice features - quiet, air quality monitor, phone app, nice appearance. Of all the air purifiers we own from various brands this is my favorite. Highly recommended.

Easy to set up. Very quiet. I am extremely pleased with its software and internet/bluetooth status. It looks great in our living room too. Mine is a white/seabed color combo.

This air purifier looks amazing. The setup was straightforward. All I had to do was turn it on, and then download the app. The build quality is top notch, and the sound of the fan is super quiet on the lowest speed, and on the highest speed, it has a nice pleasant white noise type hum. Also, this filters very quickly as measured by my air quality monitor. That said, the air purifier turns off randomly after every few hours or so. I found this highly unacceptable as the entire point of the purifier (for me at least) was for constant air purification. I have other air purifiers from other brands that have probably been turned on for years, except for the brief moments when I have to replace the filters. After some online research, I realize that this is quite a common problem with the Blueair. I promptly returned mine.

We have two long-haired dogs and this helped clean up the hair and dander.

I couldn’t be happier. This filter is quiet, and easily removed cooking smells within ten minutes on high. I have recently had a heart lung transplant and I am confident that this machine is helping to protect me now that I’m immunocompromised.

Got this for our son and he just started using it a couple of days ago. So far he likes it and is very happy with it. He likes the different settings. And it is very quiet on the lowest setting.
