摘要

The invention relates to a filter unit (10), which can be inserted into a cleaning appliance (12), in particular a vacuum cleaner, and can be removed from said appliance for cleaning. Said filter unit (10) consists at least partially of a ceramic material. To prevent damage to the vacuum cleaner during the thermal regeneration of the ceramic material, the filter unit (10) can be thermally regenerated outside the cleaning appliance (12) in an oven (14). The invention provides a reliable, cost-effective option for equipping a cleaning appliance (12) with a filter unit (10) that can be thermally regenerated.
