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 demountably coupled to the housing, the chamber having a dielectric material forming a packed bed within a charged bed region and apparatus for charging the aerosols in the air so that they may be removed when contacting the dielectric material in the bed region. An indicating device is provided to signify when the dielectric material is contaminated and should be renewed. The chamber may comprise cardboard or plastic coated with a conductive material and can be disposed of along with the contaminated material. A method for removing the respirable aerosols from air is also disclosed.
