Abstract
The invention relates to a filter cartridge for a liquid filter, in particular for use for tanks for the filtration of water for the production of drinking water, with a generally cylindrical vessel, which contains the filtering material and with a sealing screen mounted on this vessel like a cover. In order to improve the functioning of a filter cartridge, and in particular to make such a filter cartridge, which with comparatively fast liquid throughput has a good filtration action with optimum utilization of the filtering material, it is proposed in conformity with the invention that the sealing screen be covered by a distributor cap 3 essentially closed at the top and open at the side.
