A filter includes a structurally rigid adsorptive filtering medium formed as a sintered porous material chosen to remove targeted contaminant(s). The adsorptive filtering medium forms a hollow chamber sized to receive a mechanical filtering medium which is sized to press outward against the adsorptive filtering medium which supports the mechanical filtering medium thus eliminating a cage and a core to support the mechanical filtering medium and leading to a simplified construction. The fluid enters the filter through substantially the entire face of the adsorptive filtering structure and proceeds through the mechanical filtering medium which is a pleated paper filter. The hollow chamber may be capped at each end such that the caps effectively seal the filter and direct the fluid through the adsorptive filter medium and the mechanical filter medium |
