DustMagnet™ 5210i Features:

Optimal air for small to medium spaces 

Filters the air in a 20 m² room in about 12.5 min²(4.8x an hour, based on AHAM recommended removal rate) or up to 1,017 ft² in one hour on high speed to effectively lower particle levels and maintain a comfortable environment in small to medium spaces like guest bedrooms, home offices, and dining rooms.

Designed for a life with less cleaning 

Patent pending DustMagnet™ technology captures 99%² of dust before it settles. A dual air intake and vortex airflow pattern keeps airborne dust particles moving, and an electrostatic charge cluster them together. Once inside, dust particles stick to the charged stainless steel pre-filters, just like a magnet​.

Blends seamlessly into your space 

Sleek, Scandinavian design with a convenient table-top surface allows this purifier to compliment your aesthetic while working hard to clean your air. Place it where it will be most effective at capturing dust without worrying about it cramping your style.

Real-time in-app filter tracking 

Feature helps to eliminate unnecessary filter replacement with accurate and custom lifetime tracking via an algorithm. Remaining filter life is estimated based on air quality conditions. Generally, recommended filter replacement is between 6-12 months with genuine Blueair filter. 

Advanced sensors and unique in-app features 

'Welcome Home’ feature saves you time and conserves energy by automatically turning the unit on and off as you come and go to ensure clean air when entering your home. In-app 'Clean Air ETA' feature counts down time to clean air.  

*Feature only available on the Blueair app. 

Uses color to update you on air quality 

Always know the room's air quality with just a glance. An air quality indicator (AQI), located on the front of the air purifier uses a five-color LED to indicate conditions measured by its particle sensor.

Maximum filtration. Minimum noise. 

Only Blueair air purifiers use HEPASilent™ technology which provides maximum filtration with minimum noise. This dual filtration technology pioneered by Blueair combines electrostatic charging of particles and mechanical filtration using a unique filter design. Blueair air purifiers, therefore, produce more² clean air faster, cleaning your air quicker and much more quietly³ than traditional HEPA air purifiers.

Captures 99.99% of SARS-COV-2 (COVID-19)* 

*DustMagnet 5400 tested to remove SARS-COV-2 in a 1280ft³ chamber, in 60 mins on high. Performed under standard laboratory conditions and actual performance may vary. Not proven to kill SARS-CoV-2 or prevent transmission of COVID-19.

Additional Features:

  • Energy Star rated for efficiency: This certified air purifier uses less energy than an average LED lightbulb (about 10 W) at 7W on lowest setting and up to 42W on high. Confidently run it for quality air 24/7.
  • Smart device compatible: Use voice control on Amazon Alexa and Google Assistant enabled devices, or the Blueair app, to conveniently do everything from changing your purifier's settings, to putting it in auto mode.
  • Automatically adjusts to changing conditions: In Auto mode your air purifier will automatically increase fan speed when pollution levels rise in your indoor environment and return to a slower speed once the air is clean.
  • Night mode supports better sleep quality: When in night mode, your DustMagnet air purifier disables features you don't need while sleeping. This includes the Air Quality Indicator LED light and adjusting to a whisper-quiet low speed of 30dB.
  • Particle and Carbon Combo-Filter: The DustMagnet™ main filters do not only have a particle filter to remove dust and other fine particles, they also contain carbon particles integrated throughout the filter media to effectively trap VOCs, chemicals and light household odors from pets, cooking, smoking, and more.​ There are two filters, placed each at the top and bottom of the air purifier to ensure optimal removal.
