“I recommend Blueair air purifiers to my patients because of their strong performance and their commitment to third party testing, which gives me peace of mind that the airborne particles that commonly exacerbate allergy and asthma symptoms are being captured*”

Dr. Priya Bansal

“It has a night mode, which turns off all of the onboard lights and quiets the fan even more, making it the perfect option for a room where you primarily sleep and relax.”

Best For Bedrooms

“It has a quiet operation which, along with the dimmable display, makes this a great option for the bedroom—or you can set it up right by the litter box or dog crate to absorb odors.”

Best For Pet Owners

    Very Pleased

    I purchased the Blue Pure 311i+ Max for my ~600 sq ft finished basement to add some flow to what felt like stagnant air and to help with a persistent odor that I couldn't identify. Not only has the unit solved both issues, but it's super quiet and the air feels fresh and pure 100% of the time. I'm so happy with this device.

    Game Changer

    These little guys do a big job. I live in a house that’s over 100 years old and only has radiator heat, so no ductwork for any air exchange. I was shocked at how polluted the air in my bedroom was. This little guy ran strong for 10 hours and got the room into the green zone. Been there ever since. Planning to buy more for other rooms in my house. Love the design and the phone app!

    Excellent air purifiers

    I bought the two small ones because I travel as a nurse and I’d like to make sure I have one with me. And this year we’re traveling all the way to Arizona for two months and I brought both of them with. They work really well and it’s nice to have the comfort of an Air Purifier no matter who I’m staying with or where. It’s a great product.

    Excellent Unit

    There is a lot less dust on my furniture since I purchased and plugged this in. I keep it on auto 24/7 as recommended and I cannot hear the fan at all, very quiet The only time I heard the fan so far was when I was cooking and it picked up on the particles in the air, the fan increased and it showed the increase in particle count on the display, and the unit is clear across the room from the stove. This is a quality unit at a good price I am well pleased.
