Blueair 402 Replacement HEPA Filter

Blueair recommends changing these replacement air filters every 6 months. The replacement includes 1 particle filter that removes dust, pollen, bacteria, pet dander, mold spores and other airborne particles. The particle filter is made of polypropylene, which mechanically filters out airborne particles. To maximize filter effectiveness, particles are negatively charged before reaching the filters. The system uses ion technology and produces no ozone emissions. The 402 effectively purifies air in rooms as large as 365 square feet. Using patented two-stage HEPASilentTM technology, it captures 99 point 97% of the tiniest 0.1 micron particles on level one, including allergy-provoking pollen grains, dust mites, mold spores and pet dander particles. Easy maintenance: simply open the unit's lid, lift out and drop in replacement air filters every 6 months.
