A filter cartridge, in particular gravity-operated filter cartridge, having a body portion with at least one water outlet and a head portion with at least one water inlet and at least one air outlet, the head portion being arranged on top of the body portion, the body portion and the head portion together forming a housing with an inner volume, the head portion having a lower rim defining a bottom opening of the head portion, the filter cartridge further having a mesh located in the inner volume and attached to the head portion along the lower rim, the mesh separating the inner volume into an upper volume defined by the mesh and the head portion and a lower volume defined by the mesh and the body portion, treatment media being arranged in the lower volume. In order to improve the flow characteristics the filter cartridge has at least one holding-down device for the mesh, the holding-down device being movable from a standby position into an active position, in which the holding-down device is located at least partially between the mesh and the bottom opening.
