If you are signing up for auto-ship filter service, any smart-enabled air purifier of the same family enrolled in the app will be automatically signed up for the auto-ship service. Subscriptions will ship automatically based on your filter reaching 99% capacity. You can check your filter's capacity in your Blueair App.

Filters the air at a rate of approx. 4.8x an hour (or about every 12.5 minutes¹ 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.
Only HealthProtect air purifiers provide 24/7 protection against viruses and bacteria² with GermShield™ technology.¹ When on standby, the patent-pending GermShield technology proactively monitors your room and kills³ 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.
HealthProtect 7470i 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.
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 bacteria², dust, pollen, dander and mold⁴, and remove VOCs, and odors. Once caught in the filter, this unique technology then kills 99%³ of germs.
HEPASilent Ultra™ delivers 50% more clean air, uses 55% less energy and has a 10% lower noise than traditional true HEPA filtration⁵.
Verifide® by the Association of Home Appliance Manufacturers (AHAM) for performance and Clean Air Delivery Rate (CADR).
Rated as an energy-efficient air purifier by the EPA's ENERGY STAR® rating program.
Verified Zero Ozone by Intertek Sustainability. Meets UL 2988 and does not emit more than 0.0005 PPM as tested.
Certified by the California Air Resources Board for meeting the ozone emissions limit.
Awarded the 2021 iF Design Award, from one of the world’s most celebrated and valued design competitions, recognized as a symbol of design excellence around the world.
Selected as a winner of the 2021 Red Dot Design Award in the areas of product design, communication design, and design concepts.
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.
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.
Breathe easy with a 60-day in-home trial period. If you're not happy, we'll help arrange for a free return.
Guarantee clean air for years to come by extending your 1-year warranty coverage for up to 5-years.
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.
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.

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.
¹Air Changes per Hour (ACH) calculation is a product of recommended room size and average ceiling height over Pcadr
²24/7 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.
³Deactivation of germs on natural flora (excluding viruses)
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.
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).
