Abstract
An electronic air cleaner includes a housing having a fluid inlet and a fluid outlet for creating a fluid stream through the housing. Inside the housing is provided a set of first parallel conductive plates and a set of second parallel conductive plates, herein the first and second plates ar interspersed in an alternating fashion. An ionizer is provided on each of the second plates, and a source of negative high voltage is connected to each of the first plates. Particulate matter can be removed from the air stream in a method using the above-described electrostatic air cleaner.
