Abstract

A filter device includes a housing having an inlet for a gaseous medium to be filtered and an outlet for the filtered medium. Disposed in the housing is a flat carrier providing a plurality of mutually adjacent layers forming a stack. The layers are so arranged in the housing that they extend in the direction of flow of the medium from the inlet through the housing to the outlet. Adsorber particles of elongate configuration are fixed on the layers and oriented at least approximately in the direction of flow of the medium through the housing.
