Abstract: The invention relates to a filter cartridge for insertion in a filter housing of a fluid filter, comprising: a filter material configured to filter a fluid flowing therethrough from a raw side to a clean side of the fluid filter during operation of the fluid filter; and a filter-cartridge-side radio module configured to move, during operation of the fluid filter, according to the pressure difference between the raw side and the clean side of the fluid filter, which pressure difference depends on the degree of contamination of the filter material, and to communicate, in order to ascertain the degree of contamination of the filter material, with a housing-side radio module of the fluid filter, the distance (A) of which housing-side radio module from the filter-cartridge-side radio module varies upon movement of the filter-cartridge-side radio module.

Abstract: The invention relates to a filter insert for insertion into a filter housing of a fluid filter, comprising a filter material, which is designed to be flowed through by a fluid to be filtered during operation of the fluid filter from a raw side to a pure side of the fluid filter, and to a floatable radio module, which is designed to float on a water quantity located in a water collection area of the fluid filter during operation of the fluid filter.
