[ What is claimed is:] [1.]1. A water filter cartridge for use in a water treatment device having a chamber, comprising:(a) an outer shell containing water treatment material and having a central axis;(b) an inlet opening proximate a first end of said outer shell, said inlet opening being radially displaced from said central axis;(c) an outlet opening proximate a second end of said outer shell, said outlet opening being generally co-axial with said central axis;(d) a channel in said first end; and(e) a notch in said first end, said notch being radially displaced from said central axis in a direction opposite said inlet opening, and said notch being in fluid communication with said channel;(f) said channel, notch and inlet and outlet openings constructed and arranged such that water can flow from said channel, then through said notch, then away from the filter cartridge and through the chamber of the water treatment device, and then into said inlet opening.
