Abstract

A method and a device for filtering polluted air, in which the air is successively subjected to the processes of extracting grease/fat and water, drying air still containing residual humidity, and adsorbing smells/odors. The filter device includes, in a direction of flow a vortex filter, layers of expanded metal, a filter for drying the air, and an odor filter, all in a filter housing. The filter for drying the air and the odor filter are, preferably, combined in a filter cassette that is disposed on the filter housing such that it can be changed/replaced.
