Abstract: A water treatment container is disclosed having a first chamber of variable volume and an second chamber for containing a water treating agent such as an ion exchange resin. Retainers are situated on the inlet and outlet of the second chamber to retain the water treating agent within the second chamber. Filters are positioned adjacent to retainers to filter the water. The first chamber is constructed so as to have a manually variable volume. Water added to the first chamber is caused to flow through the second chamber and out a dispensing outlet as the volume of the first chamber is reduced by application of a manually applied pressure.
