The BLUEAIR Air Purifier 411a Max is a top-performing device in the Blue family’s Pure Max series, featuring proprietary HEPASilent technology for up to 83% faster cleaning and 50% less noise. Certified by Quiet Mark, it operates quietly between 18-46dB and can clean up to 526sqft in 30 minutes or 219sqft in about 12.5 minutes on high. The HEPASilent dual filtration technology delivers clean air more quickly and efficiently than HEPA filtration alone, removing at least 99.97% of airborne particles as small as 0.1 microns, including viruses, smoke, pet dander, pollen, mold allergens, and dust. The carbon filter also traps light household odors from smoking, pets, and cooking.
The purifier is designed for ease of use, with an intuitive display, a 5-color air quality indicator (AQI), and a simple two-button design for controlling fan speeds, night mode, auto mode, brightness, and child lock. The Blue Pure 411a Max Genuine Replacement Filter (Blue Pure F4MAX; B08KPJQBQT) is designed for optimal performance with this model.
Independently tested for performance and safety, the BLUEAIR Air Purifier 411a Max is AHAM Verified for performance (CADR), Quiet Mark Certified, and meets Ozone Safety Standards certified by CARB. It is also verified for zero ozone emissions (<5 ppb) by Intertek Sustainability.
