Abstract
An electrofiltration process is provided having at least one electrostatically charged polymeric film layer having surface structures. The film layers may be configured as a collection cell that has the structured film layer defining a plurality of ordered inlet openings through a face of the collection cell and corresponding air pathways, thereby forming an open, porous volume. The air pathways are defined by a plurality of flow channels formed by the structured film layers. The electrofiltration process is coupled with an ionizer which actively induces charges onto the particles to be removed by the collection cell.
