ABSTRACT:
An electrostatically stimulated air filter and process, contemplates a housing having an fluid intake and a fluid exhaust; a upstream electrode, disposed downstream of the fluid intake, for carrying a ground potential; a filter, disposed downstream of the prefilter, for filtering out contaminants in the fluid; an ionizing electrode, disposed between the filter and the prefilter, for carrying a second potential; and a downstream electrode, disposed downstream of the filter, for carrying a ground potential; and a fan, downstream of the filter, for driving air through the prefilter and the filter. Ionization of incoming fluid occurs as a result of electric fields generated by the downstream electrode, the ionizing electrode, and the upstream electrode. The filter comprises an upstream dielectric layer and a downstream conductive layer, usually fibers coated with activated carbon powder.
