NOVELTY - This utility model claims a graphene composite filter screen, fixed with the filter screen main body in external packaging frame (5) (1), wherein the filter screen main body (1) of primary filter layer (2), HEPA with graphene film and composite filter layer (3) and graphite active coal composite filter layer (4) in sequence overlap. HEPA composite filter layer and active coal composite filter layer graphene with the graphene film and composite get up form the filter screen main body, the purification effect is far exceed convention filter screen. The filtering net use of graphene film with the HEPA composite filter layer and graphene activated coal composite filter layer, so greatly improves the ratio surface area and absorbing effect of the filter screen main body, can be more effective and remove and filter toxic substance, the purification effect is far exceed convention filter screen.
