Abstract

A pleated filter media includes a plurality of parallel conductive beads to support the media and space the pleated surfaces apart. A high voltage differential applied between adjacent conductive beads induces an electrostatic field within the filter media, thereby increasing the efficiency of the filter.

Claims

a sheet of filter material;

a first conductive bead applied to said sheet of filter material and providing support for said filter material; and

a second conductive bead substantially parallel to said first conductive bead applied to said sheet of filter material and providing support for said filter material.

2. A filter in accordance with claim 1, wherein said sheet of filter material is a pleated sheet of filter material.

3. A filter in accordance with claim 1, wherein said sheet of filter material is an electret material with inherent properties that have an electrostatic charge.

4. A filter in accordance with claim 1, wherein said sheet of filter material is an electret material composed of fibers from different portions of the triboelectric scale.

5. A filter in accordance with claim 1, wherein said first and second conductive beads are applied to opposite sides of said sheet of filter material.

6. A filter in accordance with claim 1, wherein said first and second conductive beads are applied to the same side of said sheet of filter material.

7. A filter in accordance with claim 5, further including a high voltage power supply providing a potential voltage between a first terminal and a second terminal, wherein said first terminal is coupled to said first conductive bead and said second terminal is coupled to said second conductive bead.
