▎ 摘  要

NOVELTY - The utility model relates to the technical field of filter film, and claims a graphene filter film, comprising a graphene filter film, four sides of the graphene filter film are provided with a film edge, the graphene filter film is coated with a bacteriostatic agent, one surface of the graphene filter film is provided with a nano silver ion filter film, one surface of the nano-silver ion filter film far away from the graphene filter film is provided with an anti-static filter film; the inner part of the film edge is symmetrically provided with two micro reinforcing ribs, the inner side wall of the film edge is provided with a groove. the graphene filter film, coating bacteriostat and using nano-silver ion filter film on the graphene filter film, which can better filter the bacteria in the air, by using the anti-static filter film, it can effectively prevent the static conduction in the air, by using the film edge, The micro-reinforcing rib and groove can wrap the corner of the filter screen, preventing the corner damage of the filter film to be used.
