## Abstract

A filter arrangement may include a housing having an untreated space inlet and a clean space outlet and a filter insert configured to attached to the clean space outlet in the housing and to separate a clean space in the interior of the filter insert from an untreated space outside the filter insert. A lining part may be arranged on the filter insert at the clean space, wherein the lining part is configured to form a collection space for dirt retained by the filter wall in the vicinity of the clean space outlet.

## Claims

### Claim 1

A filter arrangement, comprising: a housing having an untreated space inlet and a clean space outlet and a filter insert configured to be attached to the clean space outlet in the housing, a filter wall of which separates a clean space in the interior of the filter insert from an untreated space outside the filter insert in the interior of the housing, a lining part arranged on the filter insert at the clean space, wherein the lining part is configured to form a collection space for dirt retained by the filter wall in the vicinity of the clean space outlet.

### Claim 2 (depends on 1)

The filter arrangement according to claim 1, wherein the lining is formed as a drawer configured to be pushed onto the filter insert.

### Claim 3 (depends on 1)

The filter arrangement according to claim 1, wherein the lining part is configured to be clipped to the filter insert.

### Claim 4 (depends on 1)

The filter arrangement according to claim 1, wherein the lining part is non-detachably connected to the filter insert.

### Claim 5 (depends on 2)

The filter arrangement according to claim 2, wherein the filter insert has two substantially parallel base discs connected at their mutually opposite edge zones by the filter wall, wherein the filter wall is substantially perpendicular to the plane of the base discs and penetrated by an opening connected to the clean space outlet.

### Claim 6 (depends on 5)

The filter arrangement according to claim 5, wherein the opening is arranged in a flange plate connected to the base discs.

### Claim 7 (depends on 6)

The filter arrangement according to claim 6, wherein the lining is inserted into guides on the base discs and configured to be latched on the flange plate.

### Claim 8 (depends on 7)

The filter arrangement according to claim 7, further comprising a transverse wall configured to position the drawer in a target position close to the clean space outlet, the transverse wall having an edge facing the filter insert configured to interact with a counter-latching element on the drawer-side edge of the flange plate in order to fix the drawer.

### Claim 9 (depends on 1)

A filter insert for a filter arrangement according to claim 1, wherein the lining part is formed as at least one of an integral and detachable component of the filter insert.

### Claim 10 (depends on 1)

The filter arrangement according to claim 1, wherein the filter insert has two substantially parallel base discs connected at their mutually opposite edge zones by the filter wall, wherein the filter wall substantially perpendicular to the plane of the base discs and penetrated by an opening connected to the clean space outlet.

### Claim 11 (depends on 10)

The filter arrangement according to claim 10, wherein the opening is arranged in a flange plate connected to the base discs.

### Claim 12 (depends on 11)

The filter arrangement according to claim 11, wherein the lining is inserted into guides on the base discs and configured to be latched on the flange plate.

### Claim 13 (depends on 12)

The filter arrangement according to claim 12, further comprising a transverse wall configured to position the drawer in a target position close to the clean space outlet, the transverse wall having an edge facing the filter insert configured to interact with a counter-latching element on the drawer-side edge of a flange plate in order to fix the drawer.
