Abstract
A method for filtering gas borne particles using a filter medium (13) in contact with a screen (14) composed of polymeric strands (30, 31) is described. The method is characterized by the fact that the filter medium flutters on the surface of the screen because of flow of the gas along the surface of the filter medium to generate an electrostatic charge in the medium which attracts the particles to the filter medium. Particles 0.1 micron and larger in the gas can be removed by the method.
