NOVELTY - The utility model claims a filter screen for air purifier in vehicle, comprising resin frame, upper end cover, lower end cover, resin mask, filter layer, wherein: the filter layer is composed of three layers, whcih are activated coal layer, expand graphene layer and porous graphene layer, resin mask respectively covering on the outside layer of activated coal layer, expand graphene layer and porous graphene layer, inner of resin frame flatly laid with activated coal layer, expand graphene layer and porous graphene layer and sealed with upper end cover and lower end cover. The filter screen can better lift filter effect, absorb a large amount of dust, and organic volatile matter of aldehydes and benzene, can purify air in car.
