Abstract

A filter module (1) has a housing (2) formed from a plastic and a filter (3) made from a plastic is arranged in the housing (2). The housing (2) is bonded adhesively to the filter (3) by an adhesive (15) via a first bonding surface (7, 18) made from a first plastic and via a second bonding surface (14, 19, 21) made from a second plastic. The adhesive bonding of the first bonding surface (7, 18) and the second bonding surface (14, 19, 21) is accomplished via an intermediate piece (10, 20) with the bonding surfaces (14, 18, 21) made from a plastic that is identical to or different from the first plastic. At least one of the bonding surfaces (7, 18, 19, 14, 21) has been activated by plasma or corona pre-treatment prior to the adhesive bonding.
