Sweden's No. 1 brand - 25 years of expertise in air purifiers.

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.
