Question:
When does it make sense to use the permanent filter?
Answer:
The permanent filter is only used in the Fein Dustex 25 L and 35 L models and replaces the fleece filter bag.
This is an economical way to vacuum, as you do not need a fleece filter bag.
A permanent filter serves to protect the main filter from contamination by fine dust. This significantly extends its service life.
However, the permanent filter itself and the vacuum cleaner's container must still be cleaned manually on a regular basis.
