Clean air for a healthier, happier space

Blueair’s most advanced filter, SmartFilter is designed to deliver superior performance. One particle filter layer and one active carbon filter layer combine to remove gas, odors, smoke, VOCs, exhaust, smog, and chemicals from the air. The two main filters are attached at the top, so when removing the filters you can just fold them over like a booklet to keep dust and pollutants from escaping. A smart RFID chip even tracks use and notifies you through the Blueair app when it is time to replace it, with a maximum 1 year lifetime.
Thoughtful features
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.
Easy to clean pre-filter
Simple push-out cassettes trap large particles before they enter the air purifier, extending the life of the main filter.
Alexa compatible
Change settings, enable AUTO mode, and more from your smartphone via the Blueair app or connect with your Amazon Alexa enabled device for voice control.

Why Choose Protect 7740i?

Quietly fill your room with more clean air

HEPASilent Ultra™ is our most advanced filtration technology ever. Every component is uniquely designed in Sweden to provide the maximum performance and energy efficiency. This patent-pending technology combines electrostatic and mechanical filtration to kill 99%² of germs and remove dust, pollen, dander, mold, VOCs, and odors. HEPASilent Ultra™ delivers 50% more clean air³, uses 55% less energy and has a 10% lower noise than traditional true HEPA filtration⁴.
24/7 protection against viruses and bacteria

Even when your air purifier is on standby, the patent-pending GermShield™ technology proactively monitors your room and kills⁶ 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.
More clean air to every corner of the room

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

An intuitive 5-color indicator bar gives quick updates on particle and gas levels, and a numerical display quantifies the levels for PM1, PM2.5 and PM10 particles.
Designed with smart features

Designed with smart features like Clean air ETA⁸ and real-time pollutant tracking, you can be sure your air is always clean.

Wow
I wasn't sure what I was going to think of this machine when I got it, but wow, im impressed. Super easy to setup and it looks really smart. Just as well really as it is pretty large so is quite noticable. It is extremely sensitive to anything in the air. A spray of deodorant upstairs and the machine picks that up and deals with it in a few minutes. The graph is super useful as you can see what has been happening when you are out as well. Really good machine and I'm pretty sure my air quality actually feels better. More clean and crisp.

Exceeded my expectations
This air purifier is definitely one step above most air purifiers available in my opinion. The unit itself looks very smart, it’s nicely designed and can be placed within any room. Easy to use control panel/display, touch buttons to adjust speed etc. When you switch it to automatic it tests the air quality by itself and gives you a clear numeric score via an LED panel plus there is an air quality indication display on the front top of the unit which shines and starts with Red figures for bad air quality through green to blue with a numerical indication for each colour section. This air purifier has really helped and I would highly recommend it to anyone. Excellent air cleaning power.

Perfect Purifier that really works
when i received this i was very excited to try this. my daughter suffers from asthma and the humidity that has been in the air has really been affecting it. This purifier is very easy to set up and use, its very quiet with minimal sound. when the purifier is on it has led lights which are blue for indicating good air and red for bad air. after i had put this on in my daughters room it had a effect almost immediately, that night her chronic asthmatic cough was not even heard, she slept well and felt so much better in the morning. i love the fact that it has a app to use with it, makes it so much easier to use and really well thought off! after using it for a week i have seen a big difference, its definitely a must have product for every household, it can easily be transported to different rooms if needed, at night we keep it in the daughters bedroom and during the day in the living room. it great that it blows out the cool air to clean the air in the room its been perfect for these humid warm nights.
