Your DustMagnet™ air purifier includes one set of combination particle and carbon filters, ComboFilters, that need to be replaced when your air purifier indicates it is time to change them, and two reusable stainless-steel pre-filters.
ComboFilters
The ComboFilters located the top and bottom air intakes protect against both gaseous and particulate contaminates. The particle filter media removes pollutants such as pollen, mold spores, pet dander, viruses and bacteria, fine smoke particles, and more from your indoor air. At the same time, activated carbon integrated throughout the filter traps light household odors from pets, cooking, smoke, and more. Not proven to kill SARS-CoV-2 or prevent transmission of COVID-19.
Pre-filters
A key part of DustMagnet™ technology is the two reusable stainless-steel pre-filters located at the top and bottom of the air purifier. The positively charged pre-filters act like a magnet, attracting the negatively charged dust particles.
Because this air purifier uses electrical charges, it is classified as an electronic air purifier and is tested for safe ozone emissions. All Blueair purifiers are CARB certified, meaning they’ve been tested for electrical safety and ozone emissions as part of the California EPA’s Air Resources Board, Air Cleaner Regulation (AB 2276) and found to produce an ozone emission concentration less than 0.050 parts per million.
