Abstract
The invention relates to a medical or dental-medical treatment instrument (1) having a media line, in particular for water or spray, extending from its rearward end to its forward end region, in which line an exchangeable filter element (21) is arranged. In order to reduce the flow resistance of the filter element (21), while providing a small cross-sectional size, the filter element (21) has the form of a sleeve and the direction of passage of the medium is directed transversely to the sleeve wall (21a).
