A non-woven filtering material for dust removal from heated gases contains fastened to each other by means of needle piercing two layers of synthetic fibers, a carcass layer placed between them, and also a polymeric coating. The external surfaces of both layers of synthetic fibers are fused, the polymeric coating is placed on the fused surface of one of the layers of synthetic fibers. The diameter of pores of polymeric coating is by 2.0 – 5.0 times smaller than the diameter of pores of the layer of synthetic fibers adjacent thereto. Surface density of polymeric coating is selected within the limits of 80-150 g/m2.
