Abstract

A filter housing for a filter device is provided with an inlet housing arranged upstream of a filter element. The inlet housing has an inflow opening for introducing a fluid to be purified into the filter housing. The inlet housing has an overflow opening at an outlet of the inlet housing, wherein the overflow opening conveys the fluid to be purified to the filter element. The inlet housing has an inlet channel disposed between the inflow opening and the overflow opening. The inlet channel has an intermediately positioned channel section located between the inflow opening and the overflow opening, wherein a cross-sectional shape of the intermediately positioned channel section differs from a cross-sectional shape of the inflow opening and from a cross-sectional shape of the overflow opening.
