The only air purifier to provide 24/7 protection against viruses and bacteria

Say hello to the Blueair’s most advanced air purifier ever, HealthProtect™. Every component is uniquely designed in Sweden to silently provide the maximum performance and energy efficiency. With HealthProtect™ you can be reassured knowing your family is breathing safe, germ-free air. The 7470i is a perfect solution for mid-size to large rooms and is officially certified to remove over 99.99% of the SARS-COV-2 Virus. 

HEPASilent Ultra™

HEPASilent Ultra™ is our most advanced filtration technology ever, which allows the air purifier 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 filters 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 25 dB(A) on the lowest setting and normal conversation 45 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 only uses 43 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 automatically resets the filter indicator when a new filter is inserted. Due to the smart filters we can ensure maximum performance of the unit, since we know that 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's 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.

AHAM certified room size is the size of room in which the air purifier can provide a full five air changes per hour. Therefore refreshing all of the air in the room through its filters once every twelve minutes.This is more relevant than 'maximum' room size which does not reflect an air purifiers genuine effective capability. Always be sure to only use the 'AHAM certified' room size for true comparison purposes.

CADR stands for Clean Air Delivery Rate and is an actual measurement of the amount of filtered air provided by the machine.This is the only true way to compare like for like between air purifiers when assessing how powerful they are. CADR is not the same as air volume which will always appear higher due to the fact that it is only a measurement of the units fan power (with no filter Installed).

***Carbon Filters
Carbon filters remove chemical fumes including VOC's, traffic combustion gases, pet odours, tobacco smoke and many more gaseous pollutants.However not all carbon filters are the same. Basic carbon 'sheet' filters are generally lightweight and have little capacity to adsorb these pollutants effectively. On the other hand filters containing actual carbon 'granules' are infinitely more effective and should always be chosen over carbon sheets where the most effective gaseous pollutant removal is required.

Due to continuous development and improvement, the manufacturer reserves the right to change the specification of the product or its performance,or the contents of the guide, without notice.

Having been a Blueair user for several years and having various different models from their range including the 270e, 280i, 480i each time the product got a little better and so, now with the HealthProtect I expected more.
Blueair promise big things for the HealthProtect calling it their ‘most advanced purifier ever’ but they key thing here is, does it deliver??

Read on to find out…………

The World Health Organisation estimates that 4.6 million people die each year globally purely because of poor air quality? and indoor air quality tends to be 2 to 5 times dirtier than outdoor air! An astounding set of figures don’t you think? Because of this, and because of my allergies I decided long ago that I would have an air purifier running 24/7 to keep the air as clean as possible. Before I had any Blueair device in my home, I have had other brands of air purifier, which claim to be good and just were not up to scratch. One of which I found was allowing air to bypass the filters because they weren’t sealed and this in turn filled the clean air exhaust with dust which was then put straight back into the room! It was at this point that I started researching alternatives discovered Blueair.

I have discovered no such issues with any of the Blueair products I have had and as such, I have been ‘blown away’ (sorry, couldn’t resist!) by their products. Not only is the build quality fantastic, but they are also noticeably quiet thanks to the HEPASilent technology. The 5-year warranty on products when registered is great peace of mind. I’m not shy when I review products and will not shy away from being honest when a product does not meet my expectations or do what it should, and the HealthProtect, is honestly, truly outstanding. Everything has been thought of and, in my opinion, you get what you pay for.

Let’s take a look at the features and what makes this machine so great.
The key features of this unit are:

NEW HEPASilent Ultra Smart Filter
This is Blueairs most advanced filteration technology ever which can kill 99% of germs, and also removes dust, pollen, dander, mould, VOC’s (volatile organic compounds) and odours. The filter, due to its design is also able to delivery 50% more clean air, use 55% less energy and even sports a 10% lower noise level than traditional HEPA filters. What makes it smart is that it also contains an RFID chip, which actively monitors the life of the filter, and alerts you when its time to change. To prolong the life of the filters the HealthProtect has 2 pre-filters which seal it at both dirty air inlets. This, combined with the new technology of these filter that they now last a minimum of 6 months up to a maximum of 12 instead of 6 months. The pre filters pop out for cleaning and can be put right back in. When its time to change the main filter once out of the machine it closes like a book trapping the dirt and pollutants inside. Thanks to all this, the HealthProtect is able to totally replace the air in a room upto 5 times a hour or once every 12 minutes. When the time comes to change the filter, the filter light on the control panel will light up, and the app will remind you, and, when you replace the filter with a new one, thanks to the SmartFilter the change filter light will automatically reset! Once you close the door on the purifier, the filter is sealed into place ensuring no dirty air can get around it. Replacement filters are easily available online, or you can optionally join Blueairs Filter Subscription Service, which at the time of writing provides a 15% reduction on future filter purchases.

NEW GermShield
Even if the HealthProtect is on standby, GermShield monitors the room, and will kill viruses and bacteria on the filters using low air draft and plasma charging, with a gentle air stream to prevent no new growth.

NEW SpiralAir
Unlike other air purifiers, HealthProtect’s unique SpiralAir feature delivers more clean air to every corner of the room. Instead of having 1 or 2 clean air outlets on the back or sides of the machine, HealthProtect features lots of smaller clean air outlets along both sides from the top right down to the floor at the bottom, each angled perfectly to ensure omni-directional 360-degree airflow so wherever in the room you are, the air you breathe into your lungs is clean.

On top of the unit there are several controls
Power – Turns the machine on or puts it into standby.
Auto Mode – Allows the HealthProtect to monitor and react to air changes. If it detects an issue, it speeds up, deals with the issue and drops back down to low levels again.
Fan Speed – For manual control of the fan speed.
GermShield – Turns on or off the GermShield feature.
Wi-Fi – shows Wi-Fi connection status.

Also, on top of the unit, is a digital numeric air quality display, and a 2 x 5 colour indicator bars. (1 for particles, 1 for VOC’s). Both bars are able to change colour independently of each other to provide an at a glance status of air quality. Along with the coloured indicator bars, is a numeric display which shows levels of Particulate Matter 1, 2.5 and 10 in size. A quick tap on the touch panel display will switch between the 3. (mine is currently sitting at 0 for all 3 values indicating that the air in my bedroom is clean and safe. Connecting your HealthProtect to the Blueair App means you can enable scheduling, so you are not disturbed during sleep. At night I like to have darkness and quiet and so I have scheduled mine to enter night mode at 9pm, and so at 9pm, it remains quiet, and the LED’s turn off. In the morning, it automatically resumes auto mode and the LED’s come back on. More on the app next………..

Blueair Friend App
Connecting the HealthProtect allows for a number of extra, handy features.
Current air status – The HealthProtect constantly feeds the air quality status of inside to your app so you can check for at any time. You can also check the indoor temperature and humidity.
Remote Control – Control your purifier from anywhere in the world with a Wi-Fi connection. You can control the device in the same way as you the unit itself, along with manually turn the LED’s on and off, enable auto mode etc.
Child Lock – Turning this on will disable the control on the top of the purifier and will only allow for control via the app.
Scheduling – set your device to come on and off at various times of the day, different days, speeds, and night mode.
Other Settings – You can set auto mode to react to only particulate matter in the air, or VOC’s/gasses too.
Connecting to the app will also allow Blueair to update the HealthProtects internal firmware with improvements, fixes, and new features as necessary.
If you have more than one connected Blueair device, they can all be listed in the app together regardless of model.

I strongly believe in the importance of clean air and will have Blueair Products for the rest of my life. I will be looking towards their car purifier next to protect me from exhaust chemicals whilst on the road and am excited to see what they come up with next.
