Abstract
An air filtration system includes a frame directing an airflow through the air filtration system and a media filter. The media filter includes a plurality of media fibers arranged to capture particles flowing therethrough and a conductive surface located at the media filter and having a conductivity within a selected range. Two or more contact pads are located at the media filter and are alignable with an electrical circuit located at the frame to determine whether a resistance across the conductive plane is within a selected resistance range. A method of installing a media filter in an air filtration system includes inserting the media filter into a frame of the air filtration system and aligning one or more contact pads of the media filter with one or more grounding pads of the frame. A resistance across the media filter is measured.
