The Holmes HAP9415-UA HEPA-type Air Purifier with Visipure operates quietly to help remove up to 99% of airborne particle such as pollen, dust, mold, pet dander and smoke, providing relief from odor and irritants in the air. Maximum dust removal traps and locks 30% more dust and particles. The HEPA-type filter captures particles as small as 2 microns so you can breathe comfortably. Washable pre-filter helps capture larger particles while also extending the life of the HEPA-type filter.
