What is missing is the printed installation instructions as detailed on each original bag. But that's me now do not care because I know as a filter in vacuum cleaner bags WAP Aero is mounted. So there is a small deviation to the original filter bag. So if a company in different people, the filters can only be changed with the WAP / Aero filters on the safe side.
If the filter is not correctly inserted, then you have the giant mess in the vacuum cleaner and must also renew the particulate filter.
