Abstract
The invention relates to a method for cleaning filters (22) which are designed as solid bodies having pores and/or having channels which are open towards the surface, by blasting using a blasting medium, characterised in that the blasting medium is gaseous and contains solid or liquid blasting agents, if appropriate in the form of substances having a boiling point of no more than 140° C., the blasting medium is accelerated in a jet nozzle (16, 18) so that it strikes the filter (22) at least at almost the speed of sound, and during blasting the filter (22) is disposed in front of an intake opening (34, 34′) which draws in the blasting medium as well as ambient air.
