Abstract: A multi-layered electrostatic filter and method of filtration incorporating an insulated poly glass charging element which is a grid of sufficient width to allow the air flow through the charging element to supply a static charge to the charging element and to allow trapped particles to gather and combine or coagulate along the charged element prior to reaching a dust trap which is a second layer of polypropylene filters. The initial charge is generated by friction from the dust and the air passing through a first polypropylene layer. Polypropylene is used in order to provide an insulating frame and insulating dust filters on either side of the poly glass charging element. Progressively fine layers provide for multiloading of particulate material.
