Sold by LDAS ELECTRONICS, this model is part of Blueair's Blue Pure Max series and uses the brand's proprietary HEPASilent dual filtration, which delivers clean air faster with less noise and energy than HEPA filtration alone. It cleans up to about 926 sq ft in one hour, roughly 465 sq ft in 30 minutes, and about 193 sq ft in around 12.5 minutes on high.

It removes at least 99.97% of tiny airborne particles down to 0.1 microns, including viruses and smoke, while capturing pet dander, pollen, mold, allergens, and dust; a carbon filter traps light household odors from smoke, pets, and cooking. It is AHAM Verifide for performance (CADR), CARB certified for ozone safety, and Intertek-verified for zero ozone (<5 ppb).

Day to day, it runs as low as 19dB and never louder than 48dB, and Night mode dims the lights for quiet operation while you sleep. The Blueair app adds scheduling, air quality monitoring, Clean Air ETA, Welcome Home geofencing, and 6-9 month filter tracking, with Alexa voice control available. The panel uses a five-colour AQI and a simple two-button layout with night, auto, and child-lock modes. It's Energy Star Most Efficient 2023 and draws as little as 2.5W-20W.

Dimensions are about 30 (D) x 30 (W) x 54.6 (H) cm, and it ships with one filter pre-installed plus a pre-filter. Note this product is for North America use only, with an input voltage of 110-120V.
