Abstract:
A filter-paper insert for making brewed beverages at least two layers of filter paper having a base and two opposite sides. The two layers are connected together at the base and at the two opposite sides to define an interior space that can be filled from a filling opening opposite the base. The filter paper includes a plurality of slots to increase permeability. The filter-paper insert has a lower region adjacent the base and an upper adjacent the filling opening. The lower region has fewer slots per surface area than the upper region.
