In the case of an electrostatic diesel exhaust filter the corona electrode and the collecting electrode are supplied with direct voltage with an AC component so as to obtain and even discharge. A catalyst, preferably in a noble metal catalyst, may placed upstream from the electrostatic filter in the exhaust gas pipe so that the hydrocarbons also contained in the exhaust gas may be oxidized.
