Blueair HealthProtect 7770i Air Purifier

Quietly fill your room with more¹ clean air
HEPASilent Ultra™ is our most advanced filtration technology ever. Every component is uniquely designed in Sweden to provide the maximum performance and energy efficiency. This patent-pending technology combines electrostatic and mechanical filtration to remove 99%² of bacteria and remove dust, pollen, dander, mold, VOCs, and odors. HEPASilent Ultra™ delivers 50% more clean air³, uses 55% less energy and has a 10% lower noise than traditional true HEPA filtration⁴. 

24/7 removal of viruses and bacteria⁵
Even when your air purifier is on standby, the patent-pending GermShield™ technology proactively monitors your room and removes⁶ viruses and bacteria on the filters using low air draft and plasma charging. 

More clean air to every corner of the room⁷
Unlike other air purifiers that only push clean air to a small part of the room, the patent-pending SpiralAir™ outlets are uniquely engineered to deliver 360°, omni-directional airflow - quickly circulating more clean air to every corner of the room - so you breathe clean air wherever you are. 

Air quality LCD display
A premium LCD display gives detailed updates on your air quality – concentrations of different sized particles, VOC levels, temperature and humidity. It even tracks your filter usage to let you know in real time what percentage you have left. >> Designed with smart features Designed with smart features like Clean air ETA⁸ and real-time pollutant tracking, you can be sure your air is always clean 

Blueair’s most advanced filter, SmartFilter is designed to deliver superior performance. One particle filter layer and one active carbon filter layer combine to remove gas, odors, smoke, VOCs, exhaust, smog, and chemicals from the air. The two main filters are attached at the top, so when removing the filters you can just fold them over like a booklet to keep dust and pollutants from escaping. A smart RFID chip even tracks use and notifies you through the Blueair app when it is time to replace it, with a maximum 1 year lifetime. 

Thoughtful features
Hidden wheels allow you to easily move the air purifier anywhere in the room, and the cord can be adjusted to the perfect length with a convenient winder. 

Easy to clean pre-filter
Simple push-out cassettes trap large particles before they enter the air purifier, extending the life of the main filter.
