A filter cartridge assembly incorporating a filter medium arranged between upper (4) and lower (5) pads of light, fluffy, loosely, packed fibrous matter comprising commingled, non-woven fibers of significant length relative to their diameter. The pads and filter medium are arranged within a cylindrical-shaped housing having top and bottom covers with openings sufficient to permit the free passage of both liquids and gases while substantially preventing the upper and lower pads from being dislodged from their operating positions under normal flow rate. The filter medium is preferably granulated carbon (6) of a relatively fine grain size on the order of 20 x 50 mesh said filter medium being loosely packed in the housing. The filter layers are formed from flossy fibers. The upper and lower filter pads and filter medium extend over the entire inner diameter of the cartridge, which diameter is sufficiently large relative to the thickness of the cartridge so as to produce a small pressure drop at the rated flow nominal of fluid through the cartridge. |
