Abstract

A filter device, in particular for fluids contaminated with water admixtures, such as diesel oil, has a filter housing (1) holding at least one filter element (9). The filter medium of the filter element separates an untreated side (13) from a treated side (19) during the filtration process in the filter housing (1). A water collecting unit (5) is provided and holds separated water on the untreated side. Water separated on the untreated side (13) also reaches the collecting unit (5). Mutually separated collecting chambers (61, 67) are present in the collecting unit (5) for the water discharged at the treated side (19) and at the untreated side (13).
