Abstract
A dual-filter electrically enhanced air-filtration apparatus and method are described. One embodiment includes an upstream electrically enhanced filter; a downstream electrically enhanced filter; a first control electrode adjacent to an upstream side of the upstream electrically enhanced filter; a second control electrode adjacent to a downstream side of the downstream electrically enhanced filter; and an ionizing electrode disposed between the upstream and downstream electrically enhanced filters, the ionizing electrode having an electrical potential with respect to the first and second control electrodes. Optional field electrodes may be included to enhance the electric fields associated with the upstream and downstream electrically enhanced filters.
