Abstract

A non-ionizing, clog-resistant filter material (24) for extracting fine particulate contaminants such as smoke from a gaseous fluid stream such as air uses interaction between Van der Waals forces and a non-ionizing electrostatic field to efficiently capture the contaminant particles in the filter material (24) whose pores are many time larger than the diameter of the particles to be captured. The filter material (24) is physically so configured to further enhance that interaction and is disposed between at least a pair of electrodes (18, 20) of opposite polarity.
