Abstract: The invention relates to a filter device for fluids, comprising a housing (1) accommodating at least one filter element (5), which has an inlet (47) for the supply of fluid to be purified to a non-filtrate chamber (49) of the housing (1), which is separated from a filtrate chamber (46) of the housing (1) by the filter medium (33) of the respective filter element (5), having an outlet (42) for filtrate, and comprising a magnetic field-generating unit (57) arranged inside the non-filtrate chamber (49), which has an adhering surface (51) in the form of a sleeve for ferromagnetic particles attached thereto by means of a magnetic force effect. The invention is characterized in that in the non-filtrate chamber (49), the respective sleeve (51) extends outside of the respective filter element (5) parallel to the inlet (47) and transversely to the outlet (42), and that the non-filtrate chamber (49) at least partially encompasses the outlet (42) at the point of transition to the filtrate chamber (46).
