A filter unit for brewing filtered coffee which uses basket filter bags. A special design of the filter openings of the basket filter assures an even discharge of the brewed coffee. Hot water is poured into a special distributing cover which is placed on the filter basket. Suitably designed distributing holes cause the hot water to form drops and distribute the hot water evenly over the entire amount of powdered coffee in the basket filter bag. The brewing and filtering operation is performed continuously and evenly because of these distributing holes, and thus the quality of the filtered coffee is improved.
