Abstract
A filter apparatus for producing aromatic extracts of coffee or tea includes a filter vessel having an interior with a pyramid-like shape and a filter paper insert which, in use, is adapted in shape to the interior of the filter vessel. In order to improve the utilization of the aroma carrier, the corners of the filter vessel in the usable interior are beveled or otherwise altered. The filter paper insert is correspondingly provided with creases in its corner regions so as to permit a substantially form-fitting support of the filter paper insert at the beveled corners of the filter vessel.
