Filter for Blue Pure 511

Combined particle and carbon filter for the Blue Pure 511 air purifier. The combination filter cleans the air of particulate matter like pollen, dust, pet dander, mold spores, allergens, viruses and bacteria. The carbon filter also removes smoke, odors, gases and VOC's. Blueair's world-leading filter technology uses a unique combination of both electrostatic and mechanical filtering, which means that the filtration medium can be made less dense. Less power is required to push air through the filter, which provides the highest performance at all speeds and quieter air cleaning.
