1. An active field polarized media air cleaner comprising:
a first conductive outer screen;
a second conductive screen substantially parallel to the first conductive outer screen;
a pad of material, the pad of material being disposed between the first conductive outer screen and the second conductive screen, wherein the pad of material and the first conductive outer screen and the second conductive screen are adjacent to one another, wherein the pad of material comprises multiple layers and at least one of the multiple layers is a different material from another of the multiple layers, wherein the different materials include materials combinations that create static electricity therebetween; and
a high-voltage power supply having first and second terminals, the first terminal of said high voltage power supply being connected to the second conductive screen, the second terminal of the high-voltage power supply being coupled to the first conductive outer screen.
