Disclosed is a filter attachment that removably couples with a faucet or other vessel. The attachment includes a flexible cover holding the filter on the vessel and that acts as a pressure relief mechanism if the water pressure of the faucet is above a predetermined threshold. Another flexible cover may be located on the opposite side of the attachment to allow reversible use and cleaning by backwashing. The attachment may further include a removable cap on one side that includes a flexible cover and that couples to the remainder of the attachment in a removable manner so as to allow other fitments to couple to the attachment.

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.
