Abstract
Filter media for an active field polarized media air cleaner includes two layers of dielectric material with a higher resistance air permeable screen sandwiched between the lower resistivity electric layers. The filter media may further include a mixed fiber filter layer having fibers from different sides of the triboelectric scale. The filter media may further include a layer of relatively higher density dielectric material followed by a layer of relatively lower density dielectric material.
Claims16
An active field polarized media air cleaner comprising:
- a first conductive outer screen;
- a second conductive screen substantially parallel to said first conductive outer screen;
- a pad of material, the pad of material being disposed between said first conductive outer screen and said second conductive screen, wherein the pad of material and the first and second conductive outer screens are adjacent to one another;
- and
- a high-voltage power supply having first and second terminals, the first terminal of said high voltage power supply being connected to said second conductive screen, said second terminal of said high-voltage power supply being coupled to said first conductive outer screen.
