The invention relates to a device for connecting a disposable filter to a inlet line of a filter device, which inlet line conducts fine dust. The device is characterized by an immersion pipe, which is connected to the line and which extends the line and which is height-adjustable in the direction of the in particular vertical axis of the immersion pipe and which has a cutting edge at the bottom side of the immersion pipe for cutting through a surface, in particular a film or membrane, that covers the filter interior, in particular the upper filter opening. The immersion pipe lies in the filter interior at least over part of the length of the immersion pipe in the bottom position of the immersion pipe and is located outside of the filter in the top position of the immersion pipe, such that the filter can be replaced. |
