Solid particles below 75 microns are removed in layers of porous filter material. Filtration is effected in stages according to particle size, removing the largest particles first, then the smaller particles in successive layers of filter material. Filter unit is proposed, primarily for motor vehicles, comprising housing with sealed, replaceable filter element. In a further development, pref. at least two different layers of filter material are used, arranged such that their density increases in the direction of flow. (Dwg.0/1)
