In an air filtration system of the charged media type, a disposable air filter cartridge comprising first and second dielectric fibrous filter pads; and an electrically conductive screen sandwiched therebetween; said filter pads overlapping and extending outwardly beyond the perimeter of the screen to form a marginal border surrounding the screen. The cartridge may be provided with outer conductive screens or the frame within which the cartridge is housed may provide the outer screens. A variety of cartridges constructed in accordance with embodiments of the invention is disclosed, as is a variety of cartridge and frame combinations. The disposable cartridge of the invention obviates the necessity for replacing individual pads as in prior art systems and thus facilitates servicing of the filtration medium by simply replacing the cartridge.
