<p>The method involves providing double-sided open channels (5) of a honeycomb filter (7) made of ceramic material. Current is applied at electrodes running parallel to the channels, at the filter for generation of an electrical field in the channels of the filter. Unipolar current voltages are selected such that the ratio of drift velocity of loaded soot particles in a field direction of the electrical field produced in the channels, to a channel height is larger or equal to a ratio of the middle flow rate of a gas flow in the channels to the channel length. An independent claim is also included for a filter arrangement comprising a honeycomb filter.</p>
