Our most advanced filtration combined with unique GermShield™ technology. Innovative connected features. An LED screen for quick-glance updates. All add up to give you 24/7 protection against viruses and bacteria.¹
Filters the air in a 418 ft² space in about 12.5 min² (4.8x an hour, based on AHAM recommended removal rate) or up to 2,006 ft² in one hour on high speed to effectively lower particle levels and maintain a comfortable environment in large spaces like primary bedrooms, living rooms or playrooms
Patent-pending GermShield™ technology provides 24/7 protection against viruses and bacteria using low air draft and plasma charging and kills 99% of germs caught by the filter. When on standby, a gentle stream of air proactively monitors conditions and prevents growth on the filters.
Maximum filtration. Minimum noise.
Only Blueair air purifiers use HEPASilent™ dual filtration technology, delivering maximum filtration with minimum noise. This dual filtration technology pioneered by Blueair combines electrostatic charging of particles and mechanical filtration along with a unique filter designed to produce more³ clean air, cleaning your air much faster and more quietly⁴ than traditional HEPA filtration alone.
*Protect 7400 series tested to remove SARS-COV-2 in a 1280ft³ chamber, in 60 mins on high. Performed under standard laboratory conditions and actual performance may vary. Not proven to kill SARS-CoV-2 or prevent transmission of COVID-19.
Unlike other air purifiers that only push clean air to a small part of the room, our patent-pending SpiralAir™ outlets are uniquely engineered to deliver 360°, omnidirectional airflow - quickly circulating so you can breathe clean air wherever you are.
Innovative 'Welcome Home' feature uses geo-fencing technology to put the air purifier into standby mode when you leave the house, and turn back on again as you approach home.
Feature can only be enjoyed with the Blueair app.
The SmartFilter has a smart RFID chip that proactively monitors real-time usage and accurately judges when you need to replace it, with a maximum of 1-year lifespan.
The 10i models provide at-a-glance updates on particle (left) and gas levels (right) via the LED air quality indicator bar.
Five colors represent current conditions ranging from red (very polluted) to blue (excellent) to easily keep you up to date on your indoor air.
Advanced sensors keep track of the levels of coarse particles (PM10) like dust, pollen, mold spores, and ash and fine particles (PM2.5 and PM1) like smoke, viruses and bacteria⁸. If pollutant levels creep up, the Blueair app will track the air purifier's progress with real-time 'ETA' updates until air is clean.
Feature can only be enjoyed with the Blueair app.
The Blueair app allows you to monitor your home's air quality and adjust the settings remotely with your smartphone, tablet, Alexa, or Google Assistant enabled device.
In Auto mode, the Protect air purifier automatically increases fan speed when pollution levels rise and slows it down when the air is clean again.
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.
Adjust air purifier settings like child lock, night mode schedule, LED brightness, and more to fit your lifestyle.

The technology used in Protect 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.

The Blueair SmartFilter is the only filter available for the Protect 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 Protect 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.
¹24/7 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 (deactivation) and Ecoli (growth prevention). Not proven to kill SARS-CoV-2 or prevent transmission of COVID-19.

3Comparing CADR performance of Blueair models vs same models with only H13 HEPA.
4At similar CADRs, Blueair Protect 7400 series achieved less noise than same models with only H13 HEPA. Noise refers to the dB(A) difference in acoustic power.
⁵Based on tests in a HealthProtect 7400 model comparing mechanical (Blueair SmartFilter) and electrostatic filtration with only mechanical (H13 filter) filtration, producing higher CADR (GB/T18801-2015), lower noise level (ISO3743), and lower energy consumption (ANSI/AHAM AC-1).
⁶HEPASilentULTRA™ technology combines mechanical and electrostatic filtration to provide a higher particle Clean Air Delivery Rate (pCADR) than conventional methods of only using mechanical filtration. Based on particle CADR tests (GB/T18801-2015) comparing mechanical (Blueair SmartFilter) and electrostatic filtration with only mechanical (H13 filter) filtration.
