ELECTROSTATIC CARTRIDGE FILTER

摘要

An electrostatic precipitator type filter is combined with replaceable, polarizable trapping media. In one aspect of the invention, the media is fitted between polarizing plates. In another aspect, the media is coated in sections to form a conductive surface which serve as the equivalent to the charged plates of the precipitator. These electrodes may be alternately displaced to provide a ready means to effect electrical connections.
