Extra-large rooms

Filters the air at a rate of approx. 5x an hour (or about every 12 minutes) in a 674 ft² room to effectively lower particle levels and help maintain a comfortable environment in your oversized family room, basement, or open concept area.

24/7 removal of viruses and bacteria

Only Protect air purifiers provide 24/7 removal of viruses and bacteria with GermShield™ technology.¹ When on standby, the patent-pending GermShield technology proactively monitors your room and removes² 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.

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 E. coli (growth prevention).

Ultra powerful filtration

HEPASilent Ultra™ is our most advanced filtration technology ever. This patent-pending technology combines electrostatic and mechanical filtration to remove 99.97% of viruses and bacteria,³ dust, pollen, dander and mold,⁴ and traps VOC and odors. Once caught in the filter, this unique technology then removes 99%⁵ of germs.⁰

HEPASilent Ultra delivers 50% more clean air,⁶ uses 55% less energy and has a 10% lower noise than traditional true HEPA filtration.

What technology is used in the Protect™ air purifiers?

The technology used in Protect™ air purifiers is the combination of the HEPASilent Ultra™, Germshield™ and SpiralAir technologies™.

What is HEPASilent Ultra™?

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.

What is Germshield™?

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.

What are the different settings and features available with Protect™ air purifiers?

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.

What filter can be used with the Protect™ air purifier?

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.

Blueair's Covid-19 Claims

Blueair’s product claims are derived from innovative tests developed and executed by professionals. Here, the SARS-CoV-2 testing conducted on the Health Protect 7400 was limited to measuring only the air purifier’s ability to remove the SARS-CoV-2 virus from a 13 ft3 controlled test chamber. The test did not measure whether once the virus was captured by the air purifier if it was deactivated or killed, or whether the air purifier was able to prevent transmission of the virus from person to person. Blueair is committed to transparency and veracity in making our claims, which is why we provide clarifications to ensure our products and our testing are accurately represented.   


Per the CDC’s recommendation, improving indoor air quality and ventilation can reduce the exposure to and transmission of COVID-19. An air purifier can play a vital role to improve air ventilation but cannot offer complete protection on its own. We recommend following CDC guidelines for a layered approach, including using air purifiers to aid in improving air ventilation as part of your tool kit to combat COVID-19.
