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.
Claims8
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;
- 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.
A filter media in accordance with claim 8, wherein at least one of the layers is a different material from the other layer.
