A method for operating a particle filter that filters particles contained in exhaust of motor vehicle combustion engines, the method comprising:
- conditioning the particle filter in a new condition, such that a separation efficiency of the particle filter for particles is increased relative to a value existing in the new condition, wherein the conditioning includes one of
- modifying the engine operation for a pre-set initial running distance of the particle filter installed in the vehicle such that the exhaust emitted by the combustion engine has an increased particle content compared with normal operation, or
- connecting the particle filter to a conditioning device external to the vehicle.
