    Pure Blue 311i Max

    I have bought 6 in total so far.

    The first 2 seemed to help reduce the dust accumulating on my computers. Haven't any issues yet...So i bought a few more to see how they do in dustier areas.

    Wish me luck

    Amazing how quickly it picks up on air quality

    I was astounded when the Blue Pure 311i+Max went into high while my husband was frying dinner! It's located on the far side of the living room which is the next room over from the kitchen! It picked up on pollutants in the air long before we would ever have noticed them. Wow!

    2025Blueair 311+ Max

    Very easy to use, quietest unit i've found so far on "night, 1 or 2 speed". Always indicates air is clean (?) so i run it in manual on fan speed of 1. If its actually working to clean the air, i like it alot!..: )

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.

*Comparing CADR performance of Blueair models with mechanical and electrostatic filtration vs same models with only H13 HEPA mechanical filtration.

Note: CADR and room size values have been updated to meet new DOE standards. Website listings reflect the most accurate information. You may notice slight differences versus product packaging during the transition.
