    Abstract: A filter cartridge for use in the interior of a water tank of a household appliance, the wall of which separates a housing internal side from a housing external side. A filter inlet opening which in the operation of the filter cartridge is open in relation to the external environment of a filter housing. A device for water conduction comprises at least one filter chamber having at least one filter medium and terminates in a filter outlet opening for suctioning water from the filter cartridge in the interior of the filter housing, downstream of the filter inlet opening relative to the flow direction of the water during operation. A filter port has an annular filter sealing face for the connection of the filter cartridge in a water tank. The filter sealing face has a separately disposed filter-proximal guide structure for receiving a centering element for centering the filter cartridge.

    Abstract: A water treatment system comprising filter and filter head is provided. The filter comprises: a cartridge; a cap attached to the cartridge; the cartridge comprises: first compartment comprising first water-treating medium/s; second compartment comprising second water-treating medium/s; the cap comprises a selector. The filter further comprises bypass/es extending from the selector and throughout first compartment and into second compartment, each of the bypass/es having an inlet and an outlet. In first state all water entering the filter passes through the first compartment; in second state all water entering the filter bypasses first compartment and passes through second compartment. In intermediate state/s first part of water enters the filter passing through the first compartment and a second part of water enters the filter bypassing the first compartment and passes through the second compartment. The filter head is reversibly attachable to the cap.

    Abstract: The invention relates to a method for operating a water filter cartridge in a pipe, said water filter cartridge having a housing in the form of a pressure vessel, and an inlet and an outlet for water, characterized in that a main flow of water to which minerals are added is conducted through a main pipe inside the pressure vessel, and a dosing flow of concentrated salt solution is conducted through a dosing pipe, wherein the dosing pipe branches off from the main pipe and passes through a reservoir of constant volume and in which there is a concentrated salt solution consisting of sulphate salt, chloride salt and/or hydrogen carbonate salt, wherein the part of the dosing pipe extending from the reservoir leads into the main flow at a dosing point through a dosing opening with a constant flow cross-section, and wherein a resistance section which is situated upstream of the dosing point in the main flow is used to set the flow resistance in the main flow such that a pressure difference results between the main flow and the dosing flow and causes a volumetric flow rate of the dosing flow of salt solution which is substantially proportional to the main flow, through the dosing opening into the main flow.
