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.
To achieve maximum performance we recommend placing your Blue Pure 211i Max in a room around 635 ft² room so your air purifier can clean the air at the AHAM recommendation of 4 times every 12.5 minutes. The Blue Pure 211i Max will clean a 1,500 ft² space in 30 minutes, and 3,000 ft² in 1 hour.
Operates quieter than a whisper on low at 23 db and is no louder than 53 dB on high fan speed.
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.
Register your product to extend the 1-year warranty to a 3-year warranty.

⁴Based on third-party testing of removal rate of fine particles according to GB/T18801-2015 standard and pollen removal rate according to AHAM AC/1-2019 standard.
5Based on tests in a HealthProtect 7400 model comparing mechanical (Blueair SmartFilter) and electrostatic filtration with only mechanical (H13 filter) filtration, producing higher CADR (GB/T18801-2015), lower noise level (ISO3743), and lower energy consumption (ANSI/AHAM AC-1).
6HEPASilentULTRA™ technology combines mechanical and electrostatic filtration to provide a higher particle Clean Air Delivery Rate (pCADR) than conventional methods of only using mechanical filtration. Based on particle CADR tests (GB/T18801-2015) comparing mechanical (Blueair SmartFilter) and electrostatic filtration with only mechanical (H13 filter) filtration.
