Abstract
A module for generating ions in a flowing air stream includes a support structure having a central region adapted to pass a flowing air stream therethrough, and including a plurality of supports for positioning a filamentary ion-generating electrode in a polygonal configuration within the central region. The supports and filament are relatively moveable to wipe the surface of the filament at each support for removing accumulated contaminants on the filament.
