ABSTRACT:
A reusable coffee filter with a pot-shaped hotwater container and a filter strainer adjacent an opening in the bottom of said container. The filter strainer is made of metallic sieve sheets having perforations flaring out in the flow direction. On top of the hotwater container a distribution plate is supportably held which has a plurality of holes distributed over an area corresponding to the vertical projection of the opening of the filter strainer in order to ensure a good wetting and extraction efficiency of the coffee powder.
