Abstract
The invention relates to a filter element comprising a filter material (10) which comprises individual filter folds (12) which are folded in a star-like manner, at least one fluid-permeable support element (26) which extends at least partially in the space between two adjacent filter folds (12) and/or on the inner peripheral side and/or external peripheral side of the filter folds (12). The invention is characterised in that the respective support element (26) is provided with filter-active substances or is made of said filter-active substances. A certain type of filter auxillary agent can be obtained which is used to reduce influences of fluid components which reduce the service life, in the form of specific ageing products or in the form of other agents which damage the fluid.
