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 9 months 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.

What is the warranty for the Blue Pure 211i Max?

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.

Blue Pure 511i Max
Rated 5 out of 5 stars
Bought 3 Blueairs - Great Products!
The Blue Pure 511i-Max is the third Blueair we've purchased and it does a super job! This one if for the master bedroom and we've scheduled for night time use. We have two outer Blue pure 311i Max, one in the main living room and the other in the garage. Scheduling usage is a breeze and all units clean, filter and keep our areas fresh. Garage unit filters smoke as well and eliminates all orders. Had my first filter change on the Garage unit and was straight forward and easy.

Nice and quiet, cleans the air quickly and is getting me through intense Fla allergy season in good shape! The design is attractive, and the machine is easy to keep clean. I bought reusable washable covers and put myself on the autoship filter supply list! Such a good design and easy to use! I am happy with the purchase- this is my second 311i one is in my bedroom at the other end of the home- thanks Blue Air🫶

Blue Pure 311i Max
Rated 5 out of 5 stars
LOVE the Blue Pure 311i Max!
The Blue Pure 311i Max is our third, and largest Blueair air purifier in our home. We have two small dogs (less than 20lbs), that shed. We bought this 311i Max to help with reducing allergens in the living area of the house, as it seems daily vacuums/dusting is not enough! In the short time we’ve had the 311i Max, the air quality is noticeably better. How do I know? I am not sneezing every morning when I sit and drink my coffee! And, I love the outer pre-filter sleeve…I can change the color to match the room decor and seasonal changes!

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.
