A round filter element of a filter for a urea-water solution has a filter bellows with a filter medium that continuously extends circumferentially, relative to a filter element axis, around an element interior. An end body is fastened to an end face of the filter bellows and provided with a connecting section for fastening the round filter element to a housing cover of a filter housing of the filter. The end body has a central opening communicating with the element interior. The central opening has a central insertion section for receiving a flexible separation section of a volume compensation device of the filter and has an outer flow-through section enabling flow of the urea-water solution out of the filtration volume or into the filtration volume. The filter has a volume compensation device with a flexible separation section that separates a compensation volume from the filtration volume of the filter.

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.
