A sanitary insert unit ( 1 ), which can be inserted into a discharge fitting is provided, comprising a substantially conically-shaped upstream sieve ( 2 ) with a downstream-located throughflow regulator ( 3 ) and a jet regulator ( 4 ) in a direction of flow. The throughflow regulator ( 3 ) is arranged substantially inside the inner area ( 6 ) of the insert unit, which is defined on the upper side by the upstream sieve ( 2 ). The throughflow regulator ( 3 ) has a cross-sectional shape that is substantially adapted to the cross-sectional profile of the upstream sieve ( 2 ). The throughflow regulator ( 3 ) has a rising sloping surface ( 9 ) which rises gradually in a radially inward manner from an outer, particularly annular, edge area and which leads to a control gap ( 10 ) or a similar throughflow opening that leads to the jet regulator ( 4 ). The rising sloping surface ( 9 ) and the upstream sieve are spaced apart from one another.
