Abstract
A filtration system includes a frame directing a fluid flow through the filtration system. An ionization array is located in the frame and has an ionizer current flowing therethrough. The system further includes a media filter having a plurality of media fibers arranged to capture particles flowing therethrough and a conductive surface located at the media filter and having a filter current flowing therethrough. A comparator is utilized to determine a difference between the ionizer current and the filter current, and compare that difference to a predetermined range.
