The invention relates to a filter device comprising a filter housing (10), a filter inlet (12), a filter outlet (14), and a filter element (16) which divides a filter area (18) into two partial areas (20,22). At least one of the partial filter areas is conical in form resulting from the fact that the cross-section of one partial area (20) is tapered from the filter inlet (12) to the filter outlet (14). Said partial areas are separated from each other by said filter element. This results in an optimum residence time distribution inside the filter device at a uniform flow rate, which is particularly useful for highly viscous fluids such as polymer melts or similar.
