The housing may include an untreated space inlet and a clean space outlet. A filter insert may be arranged between the inlet and the outlet and include two bottom discs that are adjacent to the side walls in the assembled state of the filter insert. The filter insert may include a filter wall extending between and connecting the bottom discs. The filter wall may extend substantially orthogonal to the housing center plane. A lateral disc may define an opening configured to be tightly connected to at least one of the inlet and the outlet. The front walls may be coupled to the bottom discs in the assembled state of the filter insert through interacting profile parts arranged on at least one of the front walls and the bottom discs into a double wall. ## Claims ### Claim 1 A filter arrangement, comprising: a housing having two front walls substantially extended on both sides of a housing center plane and a circumferential wall substantially orthogonal and connecting the front walls, the housing including an a untreated space inlet and a clean space outlet; a filter insert arranged between the untreated space inlet and the clean space outlet including two bottom discs arranged adjacent to the side walls in the assembled state of the filter insert, the filter insert including an orthogonal filter wall extending between and connecting the bottom discs, the orthogonal filter wall extending substantially orthogonal to the housing center plane, a lateral disc defining an opening configured to be tightly connected to at least one of the untreated space inlet and the clean space outlet, wherein the front walls are coupled with the bottom discs in the assembled state of the filter insert through interacting profile parts arranged on at least one of the front walls and the bottom discs into a double wall. ### Claim 2 (depends on 1) The filter arrangement according to claim 1, wherein the housing is divisible with respect to a parting plane that is substantially orthogonal to the housing center plane and in an axis of at least one of the untreated space inlet and clean space outlet, wherein the opening of the filter insert is aligned perpendicularly to the parting plane. ### Claim 3 (depends on 1) The filter arrangement according to claim 1, wherein the bottom discs of the filter insert are coupled to the front walls in a form-fitting manner. ### Claim 4 (depends on 1) The filter arrangement according to claim 1, further comprising pillar-like connections arranged between the bottom discs and configured to transmit at least one of tension and pressure forces. ### Claim 5 (depends on 1) The filter arrangement according to claim 1, wherein the profile parts are designed as guide rails together interacting with one another, which extend parallel to the axis of at least one of the untreated space inlet and clean space outlet. ### Claim 6 (depends on 5) The filter arrangement according to claim 5, further comprising insertion bevels arranged on at least one of a long end of each guide rail of the filter insert and on the other ends of each guide rail on the housing side adjacent to the parting plane. ### Claim 7 (depends on 2) The filter arrangement according to claim 2, further comprising stop surfaces extending transversely to the axis, and counter-stops on the filter insert, wherein the stops force the filter insert into a desired position. ### Claim 8 (depends on 1) The filter arrangement according to claim 1, wherein the profile parts are at least one of webs and profile strips extending parallel to the parting plane. ### Claim 9 (depends on 8) The filter arrangement according to claim 8, wherein the at least one of the webs, the profile strips, and ribs are arranged on the bottom discs. ### Claim 10 (depends on 8) The filter arrangement according to claim 8, wherein the profile strips have a profile including at least one of a T and double T-profile. ### Claim 11 (depends on 10) The filter arrangement according to claim 10, wherein a flange of the profile is distant a the respective bottom disc in the assembled state of the filter arrangement and is substantially completely enclosed by arranging profiles on the margins of the housing parts. ### Claim 12 (depends on 11) The filter arrangement according to claim 11, wherein the profile parts are webs and the profile is a double T-profile including a plurality of flanges, at least one of the webs is configured to be pushed in between the flanges of the double T-profile. ### Claim 13 (depends on 8) The filter arrangement according to claim 8, wherein the profile parts are webs and the profile includes a plurality of flanges, at least one of the webs is configured to be pushed in between a flange of the profile and at least one of transverse ribs and transverse webs are arranged on the bottom discs. ### Claim 14 (depends on 8) The filter arrangement according to claim 8, further comprising outside webs arranged on the bottom discs configured to bear against an inside of the front walls.
