The Blueair HealthProtect™ 7440i - quietly fills your room with more clean air
If you want to ease COPD, asthma or allergy symptoms, reduce unwanted household odours, gases, smoke and VOCs, eliminate airborne viruses or simply improve the air quality in your home, then the Blueair HealthProtect™ 7440i is the right appliance for you. The air purifier is suitable for all indoor environments up to 62 m2.
HEPASilent Ultra™ technology efficiently takes care of airborne pollutants
The patent-pending HEPASilent Ultra™ technology is Blueair's most advanced filtration technology ever. It combines two time-tested filtration technologies - electrostatic charging and mechanical to remove up to 99.97% of airborne particles down to 0.1 microns, trapping even the smallest viruses and microplastics in addition to dust, pollen, pet dander, bacteria and smoke.
Airborne particles receive an electrical charge that makes them ‘sticky’ – so instead of simply passing through, smaller particles stick to the SmartFilter. The filter mesh catches larger particles.
Pre-filter and 2-in 1 SmartFilter deliver superior performance
The SmartFilter comprises one particle filter layer and one active carbon filter layer. The activated carbon in the SmartFilter removes gas, odours, smoke, VOCs, exhaust, smog, and chemicals from the air.
The two parts of the SmartFilter are attached at the top, so when removing it, you can just fold it over like a booklet to keep dust and pollutants from escaping.
The built-in smart chip tracks the use of the filter and notifies you through the Blueair app when it is time to replace it. The SmartFilter must be replaced every 6 to 12 months, depending on your environment.
Simple push-out pre-filter cassettes trap large particles such as hair and dust before they enter the air purifier, prolonging the life of the SmartFilter.
GermShield™ delivers 24/7 protection against viruses and bacteria
The patent-pending GermShield™ technology proactively monitors your room and kills airborne viruses and bacteria on the filter using low air draft and plasma charging. A gentle stream of air then ensures no fresh growth of germs.
Certified by AHAM to provide you with the highest levels of allergy prevention
The Blueair HealthProtect™ 7440i is certified by AHAM (Association of Home Appliance Manufacturers) to ensure that you are using an air purifier that can genuinely improve your indoor air quality and make a real difference in your life.
Uses 55% less energy and is 10% quieter than conventional True-HEPA air purifiers
Because the HEPASilent Ultra™ technology uses a less dense filter, it requires less air pressure to push air through. This allows the Blueair air purifier to produce more clean air at lower fan speeds, which also makes it less noisy and less energy-consuming. The air purifier, when running at lower speeds, uses less energy than a traditional incandescent lightbulb.
Uniquely high particle clean air delivery rate for improved ventilation and cleaner air
The HEPASilent Ultra™ technology provides a higher particle Clean Air Delivery Rate (pCADR) than conventional methods of only mechanical filtration. This enables the air purifier to filter the air at the rate recommended by the industry of 4.8x per hour in a room up to 38 m².
The Blueair HealthProtect™ 7440i also features patent-pending SpiralAir™ outlets. They are uniquely designed to produce airflow in all directions and deliver more clean air to every corner of the room.
Particle, gas, temperature and relative humidity sensors for real-time indoor air quality monitoring
The Blueair HealthProtect™ 7440i has a dynamic screen control with a 5-colour indicator bar that gives quick updates on particle and gas levels. The numerical display quantifies the levels for PM1, PM2.5 and PM10 particles. The room temperature and relative humidity are shown on the screen.
The air quality sensors in the Blueair air purifier provide real-time indoor air quality information, allowing you to take complete control of your indoor air.
In "auto" mode, the air purifier automatically controls the airflow according to the air quality information provided by the sensors.
"Quiet Mark" certification ensures a restful night of sleep
The recipient of the "Quiet Mark" certification, the Blueair HealthProtect™ 7440i, can operate at a noise level of as low as 27 dB(A) in the "night" mode. The "night" mode runs the unit silently helping you sleep better and feel more energetic and refreshed in the mornings.
Hidden wheels for simple movement and a handy power cable winder
The two hidden wheels allow you to move the air purifier anywhere in the room. The air purifier has a manual power cable winder so that you can store away any excess cable length.
Connected experience with Amazon Alexa and Blueair mobile app
The Blueair HealthProtect™ 7440i is a Wi-Fi enabled air purifier that only requires a one-time quick set-up. You can adjust the settings such as child lock, "night" mode schedule, LED brightness, and more from your mobile device via the Blueair app. You can also connect the air purifier with your Amazon Alexa enabled device for effortless voice control.
Winner of several design awards
The Blueair HealthProtect™ 7440i is one of the most stylishly designed appliances in the industry. The recipient of the "Red Dot" and "iF Design" awards, the seal of approval of the "Good Housekeeping Institute", this powerful air purifier from Blueair is sure to add a touch of style to any room in your home.

What is HEPASilent Ultra™?
The HEPASilent Ultra™ is Blueair's technology that combines mechanical and electrostatic filtration. Compared to the HEPASilent technology (used with Blueair Classic and JOY air purifiers), the new Ultra™ technology combines an optimised fan system, electrostatic filtration and an improved filter.

Germ growth may happen when temperature and humidity levels are high. The Germshield™ functionality prevents germ growth inside the air purifier when it is not in use.
How often do I need to clean the pre-filters?
It's a good practice to clean the pre-filters once every 14 days.
How often do I need to replace the SmartFilter?
