FAQ

What pollutants does the Blue Pure 211i Max filter out?

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.

What room size is best for the Blue Pure 211i Max?

What are the noise levels of the Blue Pure 211i Max?

How often do I need to change the filters?

Your filter will last up to 1 year thanks to our proprietary RealTrack algorithm that accurately calculates the remaining filter lifetime based on fan speed, usage time and pollution levels.

When it's time to replace the filter, the filter replacement LED on the interface will turn red to remind you. Alternatively, connect to the Blueair app to receive an alert and easily re-order at the touch of a button.

Does toggling between the different PM levels (PM1, PM2.5, PM10) on the display change the specific types of pollutants that are filtered out of the air?

While many Blueair units come equipped with a PM2.5 sensor, some models, including Blue Pure 211i Max, Protect 70i, or Classic Pro CP7i, have advanced sensors that measure PM1, PM2.5, and PM10 levels for more precise air quality monitoring. However, the display on these models can only show one of these three particulate matter (PM) values at a time due to the size of the screen. The display can toggle between PM1, PM2.5, and PM10 readings to track the levels of different pollutants in their environment. Switching between these indicators does not affect the air purifier's performance or target a specific pollutant size to remove from the air. The air purifier continuously works to remove particles down to 0.1 micron from the air regardless of which PM indicator is displayed.

Kitty Litter Lifesaver
These air purifiers have been one of the best investments since I got my kitten. I love him, but he has some big bathroom odors and I don’t love that. I put a unit upstairs and one downstairs next to the bathroom where his litter box is and it has been a game changer.

Quiet and Stylish
Did some research and liked the look of the 311i Max. Wanted one with a cleanable filter as well as a HEPA. Packaging was well done, setup easy and the app works well. Super quiet machine.

Love Blueair products
Quiet but high powered. Immediately felt a difference in air quality. Wish it came with a second pre filter like my other blue air purifier.

False Advertising
The product is great but the packaging and website has false advertising. This model does NOT have sensors to monitor PM10 or tVOCs in the app, which I was expecting when I purchased.

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.
