A composite filter media having excellent dust-releasing properties provided with a layer of netting formed of a low surface free energy material that is hot calendered to the upstream surface of a supporting layer formed of non-woven synthetic fibers. A filtering layer formed of non-woven synthetic fibers is laminated to the downstream surface of the supporting layer. The filtering layer may include an electrostatic charge to increase filter efficiency at a reduced pressure drop across the composite media.
