Blueair Replacement air filter for Blue 3250i

HEPASilent™ Technology
Blueair’s HEPASilent™ filtration process captures 99.97% of airborne particles down to 0.1 micron in size. HEPASilent™ technology unites the best in electrostatic and mechanical filtration. Its revolutionary combination of advanced filter media and an encapsulated ion particle charging chamber ensures that your Blueair purifier delivers results far superior than either mechanical or electrostatic technology alone.

Pre-filter For Personal Design
With interchangeable premium pre-filters inspired by Scandinavian nature, Blue is designed to fit your personal style. Included is the Stockholm Fog (dark grey) pre-filter, but also available are Hälsinge Moss (green), Västkust Sand (pink), Gotland Limestone (beige) and Kattegatt Seabed (blue).

Easy care pre-filters
Vacuum the exterior of the fabric pre-filter to remove dust as often as you’d like. When the pre-filter requires a deeper clean, it can be washed on a gentle, low-temperature cycle in the washing machine.

Filter life
We recommend replacing the main filter every 6-9 months when used 24 hours a day and cleaning the pre-filter fabric as needed to maintain optimal performance.

Large filter area
The unique filter structure is designed to filter high volumes of air. The large surface area of the filter means more particles captured, while activated natural coconut carbon reduces household odours.
