An apparatus for improving the quality of potable water. A housing receives a replacable cartridge having an ion exchange and a bacteriostatically effective material. The cartridge is an essentially closed upright container. Partition walls divide the container into a first chamber having an inlet from which the flow is downward and a second chamber through which the flow is upward leading to a discharge opening. The inlet opening of the cartridge is higher than the discharge opening and both openings have particle filters. The second chamber extends up beyond the level of the inlet opening and is ventilated at the top. A vertical pipe inside the housing is sealingly attached at the discharge opening of the cartridge. This vertical pipe opening has its top end below the inlet opening and the vertical pipe opens with its top end below the inlet opening into a discharge passage.
