NOVELTY - The utility model relates to the field of air filter, especially claims a graphene mask. comprising a mask main body and a connection hook hanger for hanging on the ear part of with the mask main body, the mask body is arched structure, said mask main body comprises inner contact layer in contact with the skin of a wearer and surface layer in direct contact with the outside air. between the inner contact layer and the surface of the wearer, nose is set with air filter, said air filter comprises a fibre layer, a melt-blown non-woven fabric layer, graphene mixed with chitosan layer and a fibre layer; the mask main body upper mouth of wearer, nose is provided with an opening, the air filter can be inserted in or pulled out from between the inner contact layer and the surface of the mask main body through the opening. it can effectively resist anti-haze, and rational use of resource.
