Abstract
Abstract A shower water filter assembly includes a housing having a cavity for a filter element which is relatively large relative to the cross section of the water pipe to which the assembly is attached. A water inlet and a water outlet to the housing couple to a shower pipe and a shower nozzle, respectively. The cavity portion of the housing containing the filter element is laterally displaced from the inlet and outlet along the line of the shower pipe. When the filter assembly is operatively connected to the shower pipe, the filter element can be located vertically above the water inlet and the water outlet, and the height of the shower head is not reduced by the interspersed filter assembly.
