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 kill 99%² of germs 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.
Even when your air purifier is on standby, the patent-pending GermShield™ technology proactively monitors your room and kills⁶ viruses and bacteria on the filters using low air draft and plasma charging. A gentle stream of air then ensures no new growth of germs.
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.
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.
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.
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.
Simple push-out cassettes trap large particles before they enter the air purifier, extending the life of the main filter.

The technology used in HealthProtect™ air purifiers is the combination of the HEPASilent Ultra™, Germshield™ and SpiralAir technologies™.
HEPASilent Ultra™ is a combination of mechanical and electrostatic filtration, which ensures particle removal and gas reduction. Compared to the HEPASilent technology (used with Blueair Classic and JOY air purifiers), the new Ultra™ technology combines an optimised fan system, engineered in Sweden by Blueair, optimised electrostatic filtration and an improved filter.
Germ growth may happen when temperature and humidity levels are high. The Germshield™ functionality is designed to prevent germ growth inside the air purifier when the air purifier is not in use.
Three airflow speeds, Automode, Germshield™, Connection with Blueair app (see WiFi and Blueair app FAQ for more information), Indoor air quality indications on the air purifier, Filter change indicator.
The Blueair SmartFilter is the only filter available for the HealthProtect™ air purifiers.
It consists of two filters attached by a strap at the top. Each filter has a particle filter media and activated carbon.
The HealthProtect™ air purifiers also have two pre-filters that can be cleaned with a dust cloth or by using the soft brush of a vacuum cleaner.
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. HealthProtect 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.
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.
⁶Deactivation of bacteria (Staphylococcus albus) and virus (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.
