ABSTRACT:
A filter assembly particularly useful in electronically enhanced air cleaning systems including a fibrous filter media. A conductive electrode is affixed to the fibrous filter media, so that the conductive electrode makes physical contact to the fibrous filter media in a plurality of substantially planar locations. The conductive electrode is coupled to a potential that enables neutralizing charge that accumulates on the filter media during operation to be removed thereby maintaining high efficiency.
