  • Publication number: 20020098130
    Abstract: An apparatus for purifying and deodorizing air includes a housing and electrode positioned within the housing and having a plurality of emitter members extending from the electrode. A collector plate is mounted within the housing and has a plurality of holes such that a hole is positioned adjacent a respective emitter member. A high voltage generating source is positioned within the housing for applying a high voltage between the electrode and collector plate. The emitter members are moveable relative to the holes within the collector plate for selecting between: (a) an oxidating mode of operation that enhances ozone production to allow an oxygen to split off therefrom for oxidizing and neutralizing pollutants, and (b) an ionic release mode of operation for enhancing the generation of positive and negative ions such that negative ions attach to pollutants that drop out of the air.
