The most advanced purifier yet

HEPASilent Ultra™

Blueair's most advanced filtration technology yet

This patent-pending technology catches 99.97% of airborne particles including dust, pollen, dander, mold, bacteria and viruses, and then kills 99% of the germs caught in the filter. The technology combines electrostatic and mechanical filtration, which helps it deliver 50% more clean air while using 55% less energy and at noise level 10% lower than that of a traditional true HEPA filter.

Smarter functions

Gives you another level of control

The HealthProtect™ series comes equipped with support for App or Voice control, allowing you to remotely monitor the air quality of your home and adjust the settings via your smartphone, tablet, Alexa or Google Assistant enabled device. When monitoring the air in the app, the Clean air ETA function will let you track the pollutants in real time and give you an estimation on when the air will be fully cleaned, while the built-in RFID chip in the filter will let you know well in advance when it's time to change it. 

24/7 protection

GermShield™ technology will keep you protected even in low noise night mode. With a gentle stream of air, together with specially charged filters, GermShield™ proactively monitors your room and kills viruses or bacteria.

Clean air in every corner

With uniquely engineered SpiralAir™ outlets, the HealthProtect™ series can quickly circulate clean air to every corner of the room via an omnidirectional, 360° airflow as opposed to circulating air by pushing it in a single direction.

Thoughtful features

Not quite portable, but easy to move around the house. Hidden wheels makes it easy to roll your HealthProtect purifier between rooms, and with a hidden cable winder you can place it near or far a power outlet, without annoying cables poking out.

Silent operation

The HealthProtect Series only makes the sound of a whisper on low mode at 25 dB (7400) or 27 dB (7700), while only rising to that of a conversion on highest mode (45 dB for 7400, 55 dB for 7700).

HEPASilent Ultra™

HEPASilent Ultra™ is Blueair's most advanced filtration technology ever, which allows the air purifiers to deliver more clean air with less noise and less energy. This technology combines electrostatic and mechanical filtration to remove 99,97% of airborne particles such as allergens, dust, pollen, dander, viruses & bacterias, mold, VOCs, and odors. The activated natural coconut carbon has a large adsorbent surface area, and is used to effectively remove VOCs, chemicals, and unpleasant household odors. HEPASilent Ultra™ delivers 50% more clean air, uses 55% less energy and has a 10% lower noise than traditional true HEPA filtration.


Even when your air purifier is on standby, GermShield™ technology proactively monitors your room and kills viruses and bacteria on the filter using low air draft and plasma charging. A gentle stream of air then ensures no new growth of germs.


Unlike other air purifiers that only push clean air to a small part of the room, the SpiralAir™ outlets are uniquely engineered to deliver 360° omni-directional airflow. More clean air quickly circulating to every corner of the room – so you breathe clean air wherever you are.

Whisper silent

The HealthProtect™ range uses HEPASilent Ultra™ filtration technology to deliver its powerful performance  – quieter than a whisper. HEPASilent Ultra™ has a 10% lower noise than traditional true HEPA filtration. Quieter than a whisper 27 dB(A) on the lowest setting and normal conversation 55 dB(A) on the highest.

Low energy usage

The HEPASilent Ultra™ technology delivers more clean air with 55% less energy than traditional true HEPA filtration. This means that even on the highest setting, the HealthProtect™ air purifier uses 72 watts, while in the lowest fan speed is only uses 9W.

Auto Mode / Stepless fan speed operation

Selecting Auto mode means that your HealthProtect™ air purifier will automatically adjust when pollution levels creep up. With stepless, variable-speed operation, the fan increases smoothly to the right speed based on the sensor readings and slows down when the air is clean again. This ensures that your air purifier is always running at the perfect speed needed to maintain the air purity in your home.

Truly smart filter design and technolgy

RFID technology can automatically reset the filter indicator when a new filter is inserted. Due to the smart filters, Blueair can ensure maximum performance of the unit, since an original Blueair filter is inserted. Due to the booklet design of the SmartFilter Ultra, the user can simply close the filter like a book, capturing all dust and germs on the inside. The main filters are easily accessed through opening the door on the right side. Simply pull out the booklet filter by pulling the green tabs. With SmartFilter you can be assured to have clean air delivered to your home for up to 1 year. The smart sensor algorithm accurately calculates how polluted the air is and tells you when it's time to change the filter (6-12 months).

Efficient pre-filtration

HealthProtect™ comes with cleanable pre-filters, which conveniently pop-out for quick maintenance and cleaning, to significantly extend the lifetime of the main filter.

Connected Experience with Blueair app

Designed with smart features like Clean air ETA and real-time pollutant tracking, you can be sure your air is always clean. As a user you will have a visual reassurance of the air cleaning progress and estimated time until the air in the room is clean, all thanks to Blueair uniquely developed algorithm that’s tracking multiple parameters in real time. You will also have a dedicated Filter page in the app that will always display filter lifetime and it will guide you on how to order a new filter and how to replace it. With Welcome home feature, the air purifier will start cleaning the air when you are close to getting home in order to welcome you to a healthy home environment, whilst saving energy by not working all day.
