ABSTRACT:
An electrostatic air filtration system of the charged media type wherein contact between the filter media and the electrostatic charging media of the filter is minimized or eliminated to increase the efficiency of the filter. The fibrous filter media is either corrugated to minimize its contact with the charging media or separated from the charging media by nonconductive spacers. This dramatically increases the efficiency of the filter by reducing the voltage drop on the charged media caused by conduction across a filter medium in close contact with both a charged and a grounded medium.
