HEPASilent Ultra™ Blueair's most advanced filtration technology ever - quietly filling your room with more² clean air. Even when on standby, GermShield™ proactively monitors your room and activates to kill³ germs and prevent germ growth on the filter. Unlike other air purifiers, the unique SpiralAir™ outlets deliver more clean air to every corner of the room.
An intuitive 5-color indicator bar gives quick updates on particle and gas levels, and a numerical display quantifies the levels for PM1, PM2.5 and PM10 particles.
¹HEPASilent™ 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.
²Tested on the filter media. Deactivation of germs within natural flora (excluding viruses) under normal temperature and humidity conditions. Blueair air purifiers have not been tested against Coronavirus, and Blueair does not claim to capture, remove, or kill SARS-CoV-2.
³Based on testing of particle Clean Air Delivery Rate (pCADR according to GB/T18801-2015) in HealthProtect™ 7700 model at the same fan speed, compared to using H13 true HEPA filtration in the same unit.
⁴Based on testing of energy consumption (W) and noise levels (dB, according to ISO 3743) in HealthProtect™ 7700 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.
⁵24/7 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.
⁷Based on the recommended room size of 62 m² (674 ft²).
⁸Clean air ETA feature can only be enjoyed with the Blueair app.
