[ What is claimed is:] [1.] A flow-modifying assembly for installation in a discharge orifice of a sanitary fitting comprising in stacked relation elements each having an upstream and a downstream side, the elements comprising in order approaching the upstream direction an aerator element having an annular resilient male connector on its upstream side, a flow-through volume controller element having an annular resilient male connector on its upstream side and an annular female resilient connector on its downstream side and a filter element having a resilient annular female connector on its downstream side, the male connectors having the same diameter and configuration and the female connectors having the same diameter and configuration and the male and female connectors of adjacent elements being interengaged, whereby the interengaged connectors can be disengaged and the male connector on the aerator element and the female connector on the filter element can be interengaged to each other in the absence of the volume controller element.
