A method and apparatus for carrying out a laser operation, wherein a laser source is provided, wherein lasing gas is supplied from at least one lasing gas source to the laser source for the formation of a laser beam, wherein, with the aid of the laser beam, an operation is carried out, such as for instance a welding, a drilling, a cutting or a lighting operation, wherein the lasing gas which comes from the at least one lasing gas source is fed through at least one lasing gas filter before the gas is supplied to the laser source. The invention further relates to the use of a quick-change filter for cleaning gases consumed in laser processing apparatuses.
