Blueair HealthProtect 7470i Air Purifier

24/7 protection against viruses and bacteria
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).

Medium Room
Filters the air at a rate of approx. 5x an hour (or about every 12 minutes) in a 38 m² (418 ft²) room to effectively lower particle levels and help maintain a comfortable environment in your master bedroom, living room or playroom.

Captures 99.99% of SARS-COV-2
HealthProtect 7470i Shown to remove 99.99% of airborne live SARS-COV-2 when HealthProtect 7400 model 7413352000 was tested in a 13ft3 test chamber. Performance may vary depending upon the room size and location of the device within the room, quantity of particulates in the air, and product use pattern (operational settings and use duration, etc.). Not proven to prevent/reduce transmission of COVID-19.

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 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.

Removes 99.97% germs caught and bacteria growth
Through its unique combination of high airflow and electrostatic charging, HEPASilent Ultra technology removes 99.97% of germs and GermShield technology proactively monitors room conditions and activates to kill* germs and prevent growth on the filter, when on standby.

*Tested on Staphylococcus albus and MS2 bacteriophage (deactivation) and Ecoli (growth prevention). Not proven to kill SARS-CoV-2 pr [revent transmission of COVID-19. HealthProtect 7400 tested to remove SARS-CoV-2 in a 13ft³ chamber 

Unlike other air purifiers, the unique SpiralAir outlets deliver more⁹ clean air to every corner of the room.¹⁰

Less energy and noise than true HEPA filtration
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. 

Clean air ETA
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. 

Premium LCD screen
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. 

App and voice enabled for constant control
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.

Automatically adjusts to changing conditions
In Auto mode, the HealthProtect air purifier automatically increases fan speed when pollution levels rise and slows it down when the air is clean again.

Designed for flexibility
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.

²Deactivation of bacteria (Staphylococcus albus) and virus (MS2 bacteriophage).

³Based on third-party testing, using GB/T18801-2015 test standards on airborne viruses and bacteria (H1N1, Staphylococcus aureus, and Escherichia coli).

⁴Based 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.

⁵Deactivation of germs on natural flora (excluding viruses)

⁶Based on testing of particle Clean Air Delivery Rate (pCADR according to GB/T18801-2015) in HealthProtect 7400 model at the same fan speed, compared to using H13 true HEPA filtration in the same unit.

⁷Based on testing of energy consumption (W) and noise levels (dB, according to ISO 3743) in HealthProtect 7400 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

⁸Deactivation of germs within natural flora (excluding viruses) under normal temperature and humidity conditions.

⁹HEPASilent 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.
