“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

“Blueair's 311i+ Max was the best at capturing the full range of contaminants floating through the air in a typical home. Its advanced multi-level filtration captures contaminants of all sizes — not just dander and pet hair, but also cooking fumes, dust mites and pollen.”

FAQ

Our HEPASilent™ dual filtration technology removes 99.97%1 of airborne particles down to 0.1 microns, ensuring pollen, cooking odors, smoke, dust, pet dander, mold, chemicals, allergen matter and even tiny particles such as viruses and bacteria2, are captured with minimal noise and energy consumption.

¹ Tested on PM 2.5 up to 90 mins

² Based on ELISA deactivation testing of Pollen (Cry J1), Pet Dander (Fel d1, Can F1), Dust Mite Matter (Der f1) on the filter media in 60 minutes.

³ Compared to standard in-unit filter. Based on removal testing of particles 0.4-0.7 μm in 60min in a 30m3 room. Performance may vary.

⁴ When similar CADR was measured, Blueair models with mechanical and electrostatic filtration achieved less noise with less energy than same models with only H13 HEPA mechanical filtration.

⁵ AllergenBlock refers to inanimate allergens pollen, dust and pet dander.

    Love my Blueair so much just bought the Signature for another room

    You can visually see when dust gets accidentally released in the air (my renal unit has crappy metal blinds that gather dust like crazy!) and my 311i+ Max “auto” feature kicks the purifier into high gear to suck it out of the air. I literally saw the dust in the sunlight began to get sucked in toward the purifier like a vortex. Amazing!

    I live in a region where climate change has so terribly affected the area, we have destructive wildfires regularly. What was once in a blue moon thing now has become normal to experience multiple every year. I recently moved into 11 miles northwest and in my new city, about 28 miles away from wildfire started. Although my FireWatch app alerted me to the fire it was far enough away and weather conditions were fairly calm so I wasn’t concerned about evacuating at the time & temporarily quieted my notifications for 30 minutes. But then I heard my purifier kick into high gear. Inspecting what was going on causing it to put itself in high gear, I walked to that end of my unit, opened my patio door and slightly smelled the smoke but still didn’t see it. However, my 311i+ Max caught it and cleaned it up in 20 minutes!

    I didn’t realize spray deodorant was a problem but my Blueair does. Even spraying it in a second bathroom and waiting a few minutes, if I then walk into my room past my Blueair, it will automatically increase to high to clear out whatever pollutants it’s picking up from my recently sprayed on deodorant. Same when I put my favorite…

    Very quiet & easy to operate.

    Customer service was very responsive and helped making setup very easy. With the use of the app, we are able to control the device remotely. Best of all, the app allowed us to set up a schedule so that we could control and change the fan speeds, depending on the time of day, going forward without any manual intervention. And we love how quiet the system is. It also looks good.

    Would buy again!!!

    We are so happy with our purchase! This one is perfect for our LR/DR area. We use it at a 2 setting during the day and the noise is not bad at all. We like it. Easy to live with.

    No Difference

    I purchased this with hopes that it might help with allergies. Unfortunately, it has not. It is a large piece making it difficult to blend in with in the decor. The upside however, would be that it is quiet. I keep it running in hopes that there is an invisible or unknown advantage for paying $350 for a large unattractive object that sits in the corner of my living room.

    Great product.

    Love the size, i.e. two feet height, one foot diameter, round shape, 360 degree intake; very quiet, simple to use, both device manual controls and the BlueAir smartphone app, e.g. air quality status LED light.
