The two HEPASilent™ combo filters placed each at the top and bottom of a DustMagnet™ air purifier trap up to 99.97% of airborne pollutants down to 0.1 microns in size. The filters minimise the number of airborne particles that can trigger allergy symptoms, including pollen, dust, mould spores, pet dander, viruses, bacteria, and fine-smoke particles.

The carbon particles integrated throughout the media of the filters effectively remove gases, VOCs, smog, and household odours from pets, smoke, and cooking. To maintain optimum performance, Blueair recommends changing the filters every 6 - 12 months, depending on your environment. The air purifier calculates the remaining lifetime of the filters based on usage and sensor readings and indicates when it is time to replace the filter.
