HEPA filters are made of fine borosilicate fibers that are pressed together to form a net-like structure with openings large enough for air to pass through but too small for most particulates. The filters are made in sheets which are pleated to achieve maximum surface area. Americare also uses activated carbon filters to remove V.O.C.s (gases) and odors. The filters contain the highest amount of carbon possible to ensure efficiency and extended uses.
