FILTER INSERT AND DEVICE FOR TREATING LAUNDRY

A filter cartridge is provided with a filter bag and an attachment unit non-destructively releasably connected to the filter bag and used for attaching the filter cartridge to a component of the device. The attachment unit has an air inlet section. The filter cartridge comprises two elastic and buckling-resistant rails which are arranged on mutually opposite sections of the filter bag and at the mutually facing sides each have a connection member extending over at least a part of the longitudinal extension of the correspond rails and non-destructively detachably connected with the connecting member of the correspond other rail; two guide devices which are arranged on one side, of the attachment unit, facing the filter bag, wherein the rails are guided into the guide devices, and the guidedevices extend on the mutually-departing sides of the rails; and at least one releasing member which is arranged between the guide devices at the guiding-in side, and is arranged relative to the guidedevices in a way that when the rails which are connected with each other through the connection members are guided into the guide devices, the releasing member reaches between the rails and pushes the rails to be separated from each other and releases the connection members which are connected with each other.
