Catches 99% of dust before it settles
The patent-pending DustMagnet™ technology is uniquely designed in Sweden to powerfully attract airborne dust particles like a magnet before they settle on floors and surfaces. Thanks to a unique airflow in combination with charged pre-filters at least 99% of airborne dust is captured and removed so you can spend less time dusting and vacuuming.  

More clean air, less noise, less energy
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.

Designed to blend into your home
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.

Proactively adapts to you and your home
With smart connected features 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.

Auto mode
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. 

Attracts dust like a magnet
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.

Dual inlet and outlet system
DustMagnet™ air purifier is designed with dual air inlets and outlets for an optimal airborne dust removal.

Double-filter for optimal 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. There are two filters, placed each at the top and bottom of the air purifier to ensure optimal removal.

Voice control enabled
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.
