Abstract

A filter element has a filter material defining a raw side and a clean side of the filter element and to be flowed through by a medium to be filtered from the raw side to the clean side. A non-return element is disposed on the filter material. The non-return element allows a return flow of the filtered medium from the clean side back to the raw side and prevents a flow of the unfiltered medium from the raw side to the clean side. A filter and a filter system with such a filter element are disclosed. The filter system has a pump to supply medium to be filtered to the filter.
