The invention relates to a particulate filter (1) designed as a partial filter, particularly as a soot particulate filter for removing soot particles from the exhaust gas flow of an internal combustion engine, said filter comprising a filter block unit (3) that is held in a filter housing (2), is designed as a channel filter and comprises a plurality of parallel channels (6, 6.1) which are separated from one another by filter walls (7). The filter block unit (3) comprises at least two filter blocks (5, 5.1) connected one behind the other in the direction of the exhaust gas flow. Each filter block (5, 5.1) is designed as a partial filter, with a first plurality of the channels of each filter block (5, 5.1) being open on the outflow side, and a further plurality thereof being closed on said outflow side. |
