Blue Pure 211+ Air Purifier



The Blue Pure 211+ air purifier is named the Good Housekeeping Lab Pick 2020 for ‘Best overall air purifier,’ and is a top pick in Wirecutter’s “The Best Air Purifier 2020.”¹ The ENERGY STAR® certified air purifier delivers high performance with one-button control and customizable pre-filter colors in a lightweight, compact package.


Independently evaluated and third-party tested for performance as part of the AHAM Verifide® Program for room air cleaners, this air purifier has a Clean Air Delivery Rate (CADR) of 350 cfm for fine smoke particles, 350 cfm for pollen particles, and 350 cfm for dust particles.


Recommended for large rooms such as large living rooms, family rooms, and playrooms with a 360° air intake to completely filter room air about every 12 minutes² (approx. 5x an hour at 540 ft²) on the highest speed.³


The 3-step combination particle + carbon filter works with Blueair’s HEPASilent™ filtration technology to remove 99.97% of airborne particles down to 0.1 microns, like pollen, dust, pet dander, mold, bacteria, viruses⁴ and more. An additional layer of activated carbon traps light household odors.⁵


Blue Pure 211+ quietly cleans the air with noise levels equivalent to a soft whisper⁶ on low (32 dB) and up to a normal conversation on high (56 dB)–while using about as much energy as a light bulb (30-61 W)⁷p


Change color in seconds with five fabric pre-filter options. Includes two machine-washable fabric pre-filters in Diva Blue and Dark Shadow, additional colors Buff Yellow, Crystal Pink, Lunar Rock sold separately.


The fabric material of the pre-filter catches larger particles and extends the life of the primary filter. Vacuum the fabric or toss it in the washing machine whenever it needs cleaning.

All Blueair purifiers are AHAM Verified for Clean Air Delivery Rate (CADR) and given a recommended room size, certified by ENERGY STAR for energy efficiency and the California EPA Air Resources Board (CARB) for safe ozone emissions.
