Abstract: A method of cleaning a particle filter, in particular for combustion engines, includes the steps of: —a) applying heat to the interior of the particle filter during a certain time period for burning the trapped particles, —b) removing the burnt particles from the particle filter, —c) measuring the particle filter, wherein the measurements are compared to values of a unused filter of the particular type, and—if the measured values deviate from the values of the unused filter by a predetermined amount, steps a) to c) are repeated until the measured values are within an approval range. A system for performing the method is also disclosed.
