Abstract
An electrostatically stimulated air filtering device includes a dielectric filter material having an inlet side and an opposed outlet side for filtering out contaminants in an air stream directed through the device. A grounded control electrode is positioned upstream of the filter material, and an ionizer electrode is positioned between the control electrode and the filter material. A flexible ground electrode is positioned downstream of the filter material, the ground electrode being comprised of an electrically conductive painted coating confined to and in planar contact with the outlet side of the filter material.
