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. Recommended for a large space like a master bedroom, living room, or playroom; completely filters room air about every 12.5 minutes (approx. 4.8x an hour at 418 ft ) on high. 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. 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. Building on Blueair’s HEPASilent filtration technology, HEPASilent Ultra efficiently delivers 50% more clean air, 55% less energy, and 10% less noise than traditional True HEPA filtration. Meaning the Protect 7470i is quieter than a whisper (22 dB) on low, less noise than a normal conversation (45 dB) on high, and uses less energy than an incandescent lightbulb (up to 47 W) even at the highest speed. 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.
