Hombli HEPA 13 Filter

Removes up to 99.97% of airborne bacteria and viruses 
Thanks to the 3-part filter system, dirty particles such as particulate matter, pollen, allergens, mold, bacteria, viruses, cigarette smoke, dust mites, and pet dander are quickly and effectively rendered harmless. The HEPA filter captures particles (as small as 0.3 microns) and the carbon filter transforms polluted air and unpleasant odors into clean and fresh air. The filters are replaceable and last an average of 1 year, depending on usage.
