Described is a filter apparatus (10) having an activated carbon molded body (12) with a honeycomb structure. The filter apparatus (10) has connection elements (16, 18) at the feed flow end and the discharge flow end. The activated carbon molded body (12) is provided in a sealing element which is sealingly connected to the two connection elements (16, 18). The sealing element (20) is formed by a shrink tube (22) into which the activated carbon molded body (12) is shrunk and which is shrunk sealingly on to the connection elements (16, 18). The activated carbon molded body (12) can be in one piece or can comprise at least two mutually spaced activated carbon body portions (42).
