ABSTRACT:
A showerhead assembly includes a filter that is removably receivable by the showerhead. The showerhead includes a receiving opening defined within the downstream face of the showerhead, which opening is functionally adapted to receive the filter within it. The opening of the showerhead is interposed between the water inlet and water outlet of the showerhead and within the flow of water through the showerhead such that, when a filter is inserted into the opening, all water flowing through the showerhead also flows through the filter. The filter is readily insertable within the opening and it is easily removable from it. The filter includes means for securing it within the opening when the filter is inserted.
