The Blue Pure 211i+ Max HEPASilent™ smart air purifier is a high-performing unit that quickly cleanses spaces up to 1,524 square feet in just 30 minutes or 635 square feet in around 12.5 minutes on the high setting. Independently evaluated and third-party tested, this air purifier has earned the AHAM Verifide® Program certification for air cleaners, boasting a Clean Air Delivery Rate (CADR) of 410 for fine smoke particles, dust, and pollen.

Leveraging Blueair's proprietary RealTrack algorithm, the unit optimizes filter usage by monitoring fan speed, usage time, and pollution levels to accurately determine the filter's condition based on actual usage, providing timely replacement recommendations within 9 months. For optimal performance, users can purchase the genuine Blueair Blue Pure F2MAX replacement filter (model B08KPHRLXR).

Blueair's air purifiers stand out with their customizable, washable fabric pre-filters, inspired by the latest Scandinavian design trends. The Blue Pure Max series arrives with the Stockholm Fog pre-filter, while Limestone, Moss, and Sand pre-filters are also available for separate purchase.

Comparing pollen CADR on high fan speed, the Blue Pure 411a Max and 411i Max outperform the Blue 411 Auto, though other models may vary. Blueair's models with both mechanical and electrostatic filtration achieve less noise and energy consumption than similar units relying solely on H13 HEPA mechanical filtration**.

Tested in a 30m3 room, the Blue Pure 211i+ Max effectively removes at least 99.9% of S. aureus, K. pneumoniae, P. aeruginosa, MS2, E.Coli, H1N1, and A.Niger, in addition to capturing fine particulates down to 0.1 microns, including viruses, smoke, pet dander, pollen, and mold allergens***. The built-in carbon filter also traps light household odors from smoking, pets, and cooking.

Blueair's smart air purifier app offers convenient features like scheduling, air quality monitoring, Clean Air ETA, Welcome Home geofencing, and RealTrack filter tracking technology. Alexa voice control integration is also available for added convenience.

Quiet Mark certified and operating at 23-53dB, the Blue Pure 211i+ Max can clean up to 3,048 square feet in 60 minutes, 1,524 square feet in 30 minutes, or 635 square feet in around 12.5 minutes on the high setting. Blueair's HEPASilent dual filtration technology delivers faster cleaning, while using less noise and energy than HEPA filtration alone**.
