In a filter insert for use in a water outlet fitting with integrated drinking water filter, which has a structure closed on all sides and with an inner hollow space and in which at least a part of its outer surface is designed as a filter-active surface through which water to be filtered passes from the outside inward, a mouthpiece pointing outward in the shape of a collar and forming a mouth orifice is arranged which can be received by an opening in a fitting-side filter housing and from which filtered water can flow freely out of the inner hollow space without contact with the filter housing.

A multifunctional water outlet fitting for selectively dispensing service water and filtered drinking water has a fitting member having at least one water supply, a first outlet for service water which branches off from the fitting member, a second outlet for filtered drinking water which branches off from the fitting member and, for a drinking water filter, a filter receiving space through which water can flow connected to the second outlet so as to carry water. The filter receiving space is formed by a filter housing which is arranged at the end of the second outlet facing away from the fitting member, and the filter housing has a downwardly facing base in which there is formed a mouth opening, from which filtered drinking water can be removed. The filtered drinking water is consequently removed directly from the filter housing so that any formation of germs in a connected waterway is prevented.
