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.

Claims

1. 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.

2. A filter media in accordance with claim 1, wherein the material is fibrous polyester.

3. A filter media in accordance with claim 1, wherein the material is fiberglass.

4. A filter media in accordance with claim 1, wherein the material is a non-woven material.

5. A filter media in accordance with claim 1, wherein the material is subject to UV light.

6. A filter media in accordance with claim 1, wherein the material comprises multiple layers, wherein at least one of the layers is treated by a photocatalyst.

7. A filter media in accordance with claim 6, wherein at least one of the layers is a different material from the other layer.

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