Filter arrangement comprises a biofilter filled with a filter charge acting as carrier matrix for the microorganisms. The filter charge (2) of the biofilter (1) consists essentially of activated charcoal and is connected to a air moistening and nutrient solution container which moistens the air to be purified with nutrient solution and supplies microorganisms to the activated charcoal with nutrient solution.
