Our most advanced filtration combined with unique GermShield™ technology. Innovative connected features. An LCD screen for quick-glance updates. All add up to give you 24/7 protection against viruses and bacteria.¹
Filters the air in a 674 ft² space in about 12.5 min² (4.8x an hour, based on AHAM recommended removal rate) or up to 3,235 ft² in one hour on high speed to effectively lower particle levels and maintain a comfortable environment in spaces like your oversized family room, basement and open concept areas.
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.
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.
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.
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.
A premium LCD screen 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.
The Blueair app allows you to monitor your home's air quality and adjust the settings remotely with your smartphone, tablet, Amazon 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.
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 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.
²Based on third-party testing of removal rate of fine particles according to GB/T18801-2015 standard and pollen removal rate according to AHAM AC/1-2019 standard. According to AHAM, air changes per hour (ACH) is the measure of the outside air volume added to a space divided by the volume of that space over a set amount of time.
³Based on testing of particle CADR (GB/T18801-2015, particle size >0.3µm) in a HEPASilentTM /HEPASilent UltraTM unit at the same fan speed, compared to using H13 true HEPA filtration in the same unit.
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.
