Particle/Carbon Filter for Blueair 411

Advanced HEPASilent technology removes at least 99.97% of all airborne particles like PM 2.5, pollen, dust, pet dander, and mould spores down to 0.1 microns.

Activated carbon sheet reduces gaseous pollutants such as VOCs, harmful gases, chemicals and odours.

To maintain optimum performance, we recommend changing your filter about once every 6-months when used 24 hours a day. Filter fibres naturally prevent bacteria and mould growth, to ensure you'll never put bacteria and mould back into the air. The gradient filter structure traps even the smallest particles and resists clogging to maintain maximum airflow.
