The utility model discloses a novel sucked air filtering device used for a dust collector. The novel sucked air filtering device comprises a sponge layer, an electrostatic cotton layer and a protection layer which are arranged from top to bottom. The edge of the sponge layer, the edge of the electrostatic cotton layer and the edge of the protection layer are fixed through rubber rings so that an integrated structure can be formed. A plurality of vent holes are formed in the outer surface of the sponge layer. The aperture of the vent holes in the sponge layer is larger than the aperture of the electrostatic cotton layer, and air is sequentially filtered through the sponge layer and the electrostatic cotton layer. The sponge layer and the electrostatic cotton layer are used in cooperation, and therefore the air filtering effect is greatly improved, and the novel sucked air filtering device is low in cost and suitable for daily use; meanwhile, the mesh-shaped small holes are formed in the surface of the sponge layer, the interference of noise is greatly reduced, and the novel sucked air filtering device is safe, comfortable, convenient to use and practical.
