Filters the air at a rate of approx. 5x an hour (or about every 12 minutes) in a 418 ft² room to effectively lower particle levels and help maintain a comfortable environment in your master bedroom, living room or playroom.
Only HealthProtect air purifiers provide 24/7 protection against viruses and bacteria with GermShield™ technology.¹ When on standby, the patent-pending GermShield technology proactively monitors your room and kills² 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).
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 kills 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.
Through its unique combination of high airflow and electrostatic charging, HEPASilent Ultra technology kills 99% of germs caught on the filter.⁸ GermShield technology proactively monitors room conditions and activates to kill germs and prevent growth on the filter,⁵ when on standby.
Blueair purifiers are not tested against SARS-CoV-2 (COVID-19).

Unlike other air purifiers, the unique SpiralAir outlets deliver more⁹ clean air to every corner of the room.¹⁰
HEPASilent Ultra technology delivers more clean air with 55% less energy and 10% less noise than traditional true HEPA filtration.⁹ This means that even on the highest setting, the ENERGY STAR rated HealthProtect 7400 range uses only 47 watts - less energy than a lightbulb¹¹ and is quieter than a whisper (25 dB) on the lowest setting and a normal conversation (53 dB) on the highest.¹²
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 lifetime.
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 bacteria.⁰ 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.
A premium LCD display 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, Alexa, or Google Assistant enabled device.
Orders ship free and typically arrive within 5 business days in most states. Charges may be incurred for Alaska and Hawaii.

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.
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.
