Abstract
A coffee filter which may be used repeatedly is described. It comprises a funnel-shaped housing having an outlet port at the lower end. A filter of similar shape is fitted into the housing and is so dimensioned as to provide a clearance of between 0.2 to 1.5 mm. The filtering element is so dimensioned that the upper rim thereof forms a seal with the inner wall of the housing. The outlet port of the housing has a restriction in order to assume a continuous flow of the filtrate between the funnel-shaped housing and the filtering element.
