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 680i is whisper-silent on low while still effectively removing allergens. This low sound output is enabled by Dual Protection 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.

Dual Protection 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.

Blueair Fresh Air

HEPASilent filter TechnologyTM combines electrostatic and mechanical filtration to deliver especially high performance along with whisper silent operation and low power consumption. 

Airborne particles are charged before they reach the filter. This makes the particles adhere to the polypropylene fibers in the filter more easily due to electrostatic forces. This allows the use of a less dense filter, so more air can be pushed through with less noise and using less energy.

Blueair Whisper Silent

680i Filters have been specially designed with highly porous coconut carbon to naturally target asthma and allergy triggers including odors, VOC's and other gases without the need for chemical additives. 

Optimized for Blueair’s HEPASilent™ technology, these filters use coconut carbon in combination with particle fibers to remove pollutants four times faster than other carbon filters.

Blueair Fresh Air

Up to 1,550 sq. ft. of clean air. Breathe easier knowing that the 680i is verified by AHAM to circulate all of the air 2.5 times an hour in rooms up to 1,550 sq. ft.

Blueair Whisper Silent

Equipped with integrated sensors that scan the air quality in real time and adjust the fan speed to keep allergen levels low.
