Product Overview

HEPASilent technology uses a combination of electrostatic and mechanical filtration to expertly target and eliminate 99.97% of allergy and asthma triggers such as, pollen, dust, mold and pet dander, down to 0.1 micron in size. Sneezing, congestion and itchy skin caused by allergies make a good night's sleep of utmost importance. The AllergyGuard Plus is whisper-silent on low while still effectively removing allergens. This low sound output is enabled by AllergyGuard Filters which are less dense and thus allow for less air pressure. Because the filters are optimized to be used with HEPASilent technology, AlleryGuard Plus maintains a best-in-class Clean Air Delivery Rate with a quiet delivery and less low energy consumption.

AllergyGuard Plus filters are made with pol-propylene that prevents bacterial growth, are free of chemicals and binders, and resist clogging so they won't re-release particles back into the air. All-natural activated coconut carbon targets gaseous pollutants including irritating VOCs and odors that often trigger asthma.

Built-in sensors continually monitor room air quality, sending reports directly to your smartphone. Set to AUTO mode and breathe easy – the air purifier will automatically adjust fan speed in real-time to ensure allergen levels remain low. Track personalized air quality data via the Blueair Friend app, as well as check the outdoor air quality in your area so that you can plan appropriately.

Performance you can count on, each Blueair purifier is independently verified by the Association of Home Appliance Manufacturers (AHAM) for clean air delivery rate (CADR), ENERGY STAR rated, and certified by the California EPA Air Resources Board for ozone emissions. Blueair certified replacement filters should be used to maintain filter performance and warranty, and replaced about every 6 months, depending on use.
