Abstract
The invention relates to a filter element for fluid filtration, in particular for hydraulic fluid, consisting of element components, such as a preferably pleated and multi-layer filter material (10) that extends between two end caps (26) and at least partially comprises a fluid-permeable supporting tube (14) forming a hollow cylinder, characterized in that at least one element component of the filter element is provided at least partially with at least one luminescent material or another marker in such a manner that said material or marker is excited to a characteristic, detectable wave emission when exposed to a certain exciter wave or wave spectrum.
