An ion diffuser has a frusto-conical surface made of thin metal in which surface are a plurality of emitter orifices. Around the perimeter of each orifice are a plurality of raised points that are angled toward a stream of dirty gases flowing through each emitter port. Submicron particles are ionized as they pass through the orifices when the metal is energized positively from a high voltage powerpack. A fan, to which are connected filaments, rotates above the frusto-conical surface and the submicron particles are collected by the filaments.
