Our unique filtration technology that we call HEPASilent™ sets us apart. The combination of electrostatic and mechanical filtration allows us to use filters that are less dense and require less air pressure than traditional HEPA filters without a loss in performance — resulting in quieter and more energy efficient air purifiers.
With a convenient top surface that doubles as a side table, DustMagnet™ air purifier is designed to blend into your home like a great looking piece of Scandinavian furniture. No need to hide your air purifier, place it where it will be most effective.
With smart connected features³ like Welcome home and Clean air ETA, that you can enjoy with the Blueair app, you can control the air quality condition in your home wherever you are.
DustMagnet™ air purifier features an Auto mode function with a smart sensor that monitors real-time air quality conditions and auto-adjusts to optimize performance ensuring clean air in your home.
Unique to the DustMagnet™ air purifier are the two stainless steel pre-filters that are constantly being positively charged, that effectively attract dust particles just like a magnet.
DustMagnet™ air purifier is designed with dual air inlets and outlets for an optimal airborne dust removal.
The DustMagnet™ main filter do not only have a particle filter, it also contains carbon particles integrated throughout the filter media to effectively remove fine particles, dust, gas and VOCs from the air.⁴ There are two filters, placed each at the top and bottom of the air purifier to ensure optimal removal.
By using compatible voice service such as Amazon Alexa, Google Home or Tmall Genie, you can conveniently control your DustMagnet™ air purifier with voice instructions.
In Auto mode, the air purifier automatically increases fan speed when pollution levels rise and slows it down when the air is clean again.
Adjust settings like child lock, night mode schedule, LED brightness, and more remotely via the Blueair app or Amazon Alexa enabled device.
Completely filters room air in rooms up to 20 m² (4.8 air changes per hour) and up to 48 m² (2 air changes per hour). Blueair recommends 4.8 air changes per hour according to AHAM.

¹ Refers to the removal of 99% of airborne dust particles (0.5-3 µm) in 33 min on highest fan speed based on AHAM AC-1 protocol; not applicable to larger particle sizes and particles that have already settled on surfaces. "Dust" defined as airborne dust.
² HEPASilent™ technology combines mechanical and electrostatic filtration to provide a higher particle Clean Air Delivery Rate (pCADR) than conventional methods of only using mechanical filtration (at the same rpm on the fan and energy consumption of 18,3W). Based on internal testing on particle CADR according to GB/T18801-2015 standard.
³ Features can only be enjoyed with the Blueair app.
