ABSTRACT:
An apparatus for removing respirable aerosols (typically within the size range of about 0.1 to about 2 microns in diameter) from air comprises a housing and a chamber removably coupled to the housing so as to extend outwardly therefrom. The chamber contains a dielectric granular material forming a packed bed within a charged bed region and an apparatus spaced from the bed region for charging the aerosols in the air so that they may be removed when contacting the dielectric material in the bed region. The granular material is retained between two spaced apart gas permeable electrodes disposed adjacent an outlet end of the chamber and the charging apparatus is disposed adjacent the inlet end and is defined by a gas permeable support member having charging electrodes supported thereon or formed as an integral part thereof.
