Abstract: This invention relates to a filtering apparatus for filtering liquids, in particular beverages. To attain an effective seal between two superimposed filter supports and the associated filter bodies in such a filtering apparatus, the upper side of an underlying filter support has formed therein a groove which opens upwards and has a substantially trapezoidal cross section and whose interior groove wall is substantially parallel to the inner wall of the apron of the filter support respectively lying thereabove, and the profiled seal has, on the whole, a substantially rectangular cross section, with the profiled seal portion supported on the respectively lower filter support being adapted to the cross section of the groove.
