Protect™ is equipped with HEPASilent Ultra™, 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%⁴ of bacteria and remove dust, pollen, dander, mold, VOCs, and odors. HEPASilent Ultra™ delivers 50% more clean air⁵, uses 55% less energy and has a 10% lower noise than traditional true HEPA filtration⁶.
Even when your air purifier is on standby, the patent-pending GermShield™ technology proactively monitors your room and removes viruses and bacteria on the filters using low air draft and plasma charging.
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. Designed with a booklet style frame, so when removing the filters, you can just fold them over like a booklet to keep dust and pollutants from escaping. Equipped with a smart RFID chip to accurately monitor filter status and automatically reset the replace filter reminder when a new filter is installed.
Advanced sensors keep track of the levels of coarse particles (PM10) like dust, pollen, spores, and ash and fine particles (PM2.5 and PM1) like smoke, viruses and bacteria. These allow you to monitor the pollutants in your home so you can understand how your activities and product choices are impacting your air quality. If pollutant levels ever creep up, the Blueair app will track the purifier's progress to give you real-time updates until your air is clean.⁷
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.
The Blueair app allows you to monitor changes in your home's air quality and ensures it never becomes unhealthy. You can easily adjust the settings remotely from your smartphone or tablet, or with Alexa or Google Home for voice-enabled operation.

¹Protect™ is the only air purifier with GermShield™ technology where 24/7 protection refers to the key function of GermShield™ technology, that is activated when the unit is in standby mode. Tested on Staphylococcus albus and MS2 bacteriophage. Protect 7400 series shown to remove 99.99% of airborne SARS-CoV-2 in a 0.37 m³ biosafety lab chamber. Not proven to kill SARS-CoV-2 or prevent transmission of COVID-19. Other Blueair air purifiers have not been tested against SARS-CoV-2.
²HEPASilent™ technology combines mechanical and electrostatic filtration to provide a higher particle Clean Air Delivery Rate (pCADR) than conventional methods of only using mechanical filtration (at the same rpm on the fan and energy consumption of 18.3W). Based on particle CADR tests according to GB/T18801-2015 standard.
³Deactivation of bacteria (Staphylococcus albus) and virus (MS2 bacteriophage).
⁴Tested on the filter media. Deactivation of germs within natural flora (excluding virsues) under normal temperature and humidity coniditons.
⁵Based on testing of particle Clean Air Delivery Rate (pCADR according to GB/T18801-2015) in Protect™ 7400 model at the same fan speed, compared to using H13 true HEPA filtration in the same unit.
⁶Based on testing of energy consumption (W) and noise levels (dB, according to ISO 3743) in Protect™ 7400 model with the same particle Clean Air Delivery Rate (pCADR according to GB/T18801-2015), compared to using H13 true HEPA filter in the same unit.
