"Blueair's most advanced air purifier, Protect provides 24/7 protection against viruses and bacteria. Each aspect of the Protect 7470i air purifier is uniquely designed for maximum performance, quiet, clean air delivery and energy efficiency, with innovative smart features. Independently tested for performance as part of the AHAM Verified Program for room air cleaners, for a Clean Air Delivery Rate (CADR) of 270 for fine smoke particles, 280 for pollen particles, and 275 for dust particles. Protect's HEPASilent Ultra filtration technology filters 99.97% airborne particles, like viruses and bacteria; dust, pollen, dander, and mold, then kills 99% of the germs caught in the filter. Only Blueair air purifiers use HEPASilent™ technology, delivering maximum filtration with minimum noise. Combining mechanical filtration with electrostatic charging of particles produces clean air up to 45% faster with up to 67% less noise than traditional HEPA filtration alone. The combination SmartFilter uses an activated carbon layer to remove gases, volatile organic compounds (VOC), chemicals, and household odors from wildfire smoke, pets, cooking, and more. Protect air purifiers use SpiralAir omnidirectional airflow to quickly circulate more clean air to every corner of the room. GermShield technology proactively monitors room conditions and activates to kill germs and prevent growth on the filter, when on standby. Pair with the Blueair app to unlock smart features like Clean air ETA to count down the time until clean air and Welcome home function to automatically set your air purifier to standby when you leave home and back on to clean the air just before you return.

Not proven to kill SARS-CoV-2 or prevent transmission of COVID-19; Tested on E.coli (excluding viruses).
CLEAN AIR IN A MATTER OF MINUTES: Comparing CADR performance of Blueair models vs same models with only H13 HEPA. At similar CADRs, Blueair models achieved less noise than same models with only H13 HEPA. Noise refers to the dB(A) difference in acoustic power.
