Abstract
Abstract The air ionizer comprises a sealed insulating housing containing a high voltage power supply and a half-wave modifier. Conductive brushes or filamentary elements are provided on the outside surface of the housing and are coupled to the power supply, either resistively or capacitively, so that they generate ions in the surrounding air. Capacitive coupling is to a conductive layer on the inner surface of the housing.
