Customer Ratings & Reviews

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.

quiet and efficient. Great product that I would def purchase again.

sleep mode is very quiet! I was worried it might keep me awake as I am a light sleeper. I am very happy with it.

Love this thing keeps our air purified pick up particles when you think there’s nothing to worry about sleep better at night

You’ll notice a difference in air quality immediately. Nice size, unobtrusive. Good quality. Replacement filter a bit pricey.

Very Quick set up, very quiet. I noticed a big differnece. I love it!!

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.

Works great on any setting. It is very quiet and looks great with any decor.

I’ve had the air cleaner for about a month and am happy with it. In auto mode it’s very quiet, barely noticeable. It responds to changes in air quality, kicking the fan on higher when there are cooking odors or dust. I’m not interested in using the app, and it runs fine manually. The only con is size, it takes some floor space.

The machine works well. I enjoy having it at home.

The Blueair air purifier has been money well spent. I could immediately smell the difference in the air quality in my basement family room. I always woke up with a stuffy nose whenever I fell asleep there, but ever since I got my Blueair, I feel great and breathe better.

This has been a game changer for me! I constantly felt like I had a cold or allergies from sleeping in a downstairs bedroom. After several days use those symptoms are now gone! Highly recommended!

The blue air 311i is a fantastic purifier, I smoke in my household and it detects it and the particle count goes up accordingly. And cleans the air in about 45 minutes on max settings. The app is easy to use and works well.

Excellent item, very quite and esthetically pleasing.

The Blue Air purifer runs whisper quite in the background except for when it detects particles in the air and even then it's not really noticeable . It has an auto mode along with other manual modes which really helps if you have pets. We plan on purchasing another one.

VERY QUIET & REFRESHING FROM THE MOMENT I PLUGGED IT IN & BEGAN USING IT.

We clearly see and feel the difference. Very quiet, easy to set up. We use it in our bedroom/master bath area and it is great. The wife especially notices the difference in her breathing and nasal congestion.

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.

Almost immediately started breathing better. I've have a persistent dry cough for months and scratchy eyes for the last two weeks. Both went away. Not sure what's in our air, so that's concerning, but this air purifier is holding it at bay.

This has been a life change to my allergies and stuffiness that I used to wake up to and congested from my ceiling fan. I havent used my ceiling fan since i purchased this item. It cleans the air and feels so clean and fresh in my room. I highly recommend this purchase as you will wake up feeling refreshed and breathing very well.
