A filter cartridge, for an internally by-passable water purifier apparatus, is in the form of a tubular shell that has inlet and outlet walls with at least one opening being defined in each. A water filtering material is disposed within the shell. Running lengthwise of the shell is an arrangement for guiding water from the inlet to the outlet regions and exclusive of the filtering material. That arrangement is either interiorly of or external to the shell. |
