Cleaning the HEPA exhaust filter (Ultra HEPA hygiene
filter)
The HEPA filter is designed so that it does not need to
be replaced, provided the appliance is used as inten-
ded in the household.
To ensure that the vacuum cleaner is working at its op-
timum power level, the HEPA filter should be rinsed out
after one year. The filtering action of the filter remains
intact, even if the filter surface becomes discoloured.
