Abstract
A filtering device for the preparation of coffee comprises a vessel with a permanent metallic filter disk forming the bottom thereof. Vertically extending walls divide the vessel into distinct compartments of varying volumetric content, thus separating distinct areas of the filter disk. A water inlet is provided for one of the compartments in which the coffee powder is placed so that the amount of water used at any one time determines the active area of the filter disk utilized by virtue of the overflow between compartments.
