ABSTRACT:
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.
The cartridge is usable in a purifier apparatus that has a housing with an inlet for the flow of water as well as a single outlet area for discharging the flow of water. A channel defines the path of water flow from the inlet to the outlet, and a chamber is defined in that channel in the path of the flow. One valve is disposed in the channel for controlling the flow of water from the inlet through the cartridge to the outlet. In addition, another valve is disposed in the channel for controlling the flow of water from the inlet to the outlet along a path that by-passes the cartridge.
