A device for the suction filtration of fluids, such as urea solutions for exhaust gas after-treatment systems, has a tank () storing the fluid, and a filter element () arranged in the tank and provided with a filter medium () separating the tank contents from a clean-side inner filter cavity (). The filter cavity extends from the bottom () of the tank () to a filling level height () and corresponds to a part of the filling volume of the tank (). On the filter cavity (), a suction connection () discharges the cleaned fluid by a suction pressure corresponding to a system operating pressure. The filter element () is provided with a filter medium (), which is air-impermeable if suction pressures are within the range of a low system operating pressure.
