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.

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.

Great buy does the job for my 20x20 master bedroom

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.

Ideal air purifier since I live in a different state so I am able to control the unit from afar...air in the house is much cleaner. Doesn't take up much space for a large amount of space that is covered. Price was on sell which made it a very good deal. I am thinking about getting a unit for my home in Michigan too

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!

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.

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

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

Whisper quiet air purifier. Measures the air quality accurately and works accordingly. I would recommend this.

Easy to use, does a great job of cleaning the air. I especially like the web app that allows you to control the device.

I exclusively use this brand of air purifiers, they’ve always been extremely helpful and as someone with allergies to dust and cats in the home- it really makes a difference.

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.

I’ve had two for a month now. I have noticed a huge improvement with my allergies!

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

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.

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

I recently started using this air purifier, and I’m genuinely impressed with how it clears the air. It’s amazing how fresh the air feels now, much better than what I’ve experienced with other big brand air purifiers. The difference is noticeable—I can really tell that the air is cleaner and more refreshing.

Quiet, efficient, and cleans the air very well. AAA+++

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.
