    Abstract: An original water purification system produces potable water, which is held in the filtrate vessel (1). This includes a lower, tapered-collar (3), cartridge (4) holder (2), and an inter-chamber (5). On the lower holder (2), rests a tapered-collar (7) cartridge (8) holder (6); above this is the upper tank (9) with filter supply system (10). Original features include the separate and lower arrangement of the upper cartridge holder (6) in relation to the upper tank (9). The tapered collar (3) of the lower cartridge holder (2) is higher than the first tapered collar (7) of the upper cartridge holder (6) in the filtrate vessel.

    Abstract: In order to make the exhaustion of the ion exchanger visible in a device for water treatment using a weakly acidic or weakly basic ion exchanger contained in a tube, whose inlet opening is in the area of one end and whose outlet opening is in the area of the other end, each being formed by a device permeable to liquid but retaining the ion exchanger, a chamber (5), which contains a strongly acidic or strongly basic ion exchanger (8) with a colour indicator bound to this and having its wall at least partially composed of a transparent material, is disposed in the area of the outlet opening (4) of the tube (1).
