NOVELTY - A graphene air filter, comprising a filter base, the filter plate base layer comprises two layers of polyimide fibre fabric, between two layers of polyimide fibre fabric is formed with a layer of active carbon particle layer. and further forming a layer of plant fibre layer between the active carbon particle layer and two layers of polyimide fibre fabric, at the same time, on the outer surface of the filter sheet base layer on one side of the polyimide fibre fabric formed with a layer of cotton, while the outer surface of the other side of the polyimide fibre fabric is laminated with multiple groups of graphene composite layer. the graphene composite layer have the same structure, and each group of graphene in the composite layer comprises a layer of graphene and graphene formed on the, lower surface of polypropylene spun-bonded non-woven fabric. The utility model has good dust filtering effect, has good PM2.5 filtering and sterilizing effect.
