    Abstract: A method for designing and/or controlling a filter assembly for the air supply to a turbomachine includes: calculating a current and/or an expected concentration of particles inair present at an inlet of at least one filter stage of the filter assembly as a function of a mean size of the particles; calculating a sensitivity spectrum that, depending on the mean size of the particles, indicates an extent to which a predetermined concentration of such particles has a negative effect on performance and/or on service life of the turbomachine; calculating, for at least one filter candidate usable in the filter stage and/or switchable on or off, a concentration of particles to be expected at an outlet of the filter from a concentration and filter properties of the at least one filter candidate; and calculating a quality rating from the concentration and a sensitivity spectrum.
