1. A fine filter part kit, comprising:
a replacement fine filter part that is adapted to be mounted to a fine filter section for a dust extractor, wherein the fine filter part kit further comprises a filter lid that is adapted to be mounted to a corresponding used fine filter part to be replaced, already mounted to the fine filter section, and thereby seal an opening of a particle containing space inside the used fine filter part before removing the used fine filter part, such that release of particles contained in the particle containing space into the ambient air is prevented and a secure disposal of the used fine filter part is enabled.
