Abstract:
1. An electronic air filter comprising: a) a frame having an electronics-support side; b) external polarizing screens contained within said frame; c) polarizable dust-trapping media contained between the external screens; d) a central screen contained within the external polarizing screens and separated from said external polarizing screens by said dust-trapping media; e) a channel with an inner volume mounted along said electronics-support side of the frame, said channel not extending the full length of said electronics-support side; f) a high voltage supply electronics box containing a high voltage power supply having a protruding end portion, wherein said protruding end portion is dimensioned to interfit within the inner volume of the channel so that the channel/box combination collectively acts as an extension to the filter frame, providing the filter with the shape of a completed rectangle so that, when it is installed in an air handling unit, it will seal properly, directing air to pass only through the filter medium.
