anko EV-696-S222 Manual page 17

NOTE: Never use the vacuum cleaner with a wet or damp filter or without the
filter fitted.
Using a wet or damp filter will damage the filter, may cause serious damage
to the vacuum cleaner and will void your warranty.
Only wash the white filter if it is very dirty, otherwise just tap the edge of the
filter on a hard surface to dislodge any dust and debris.
To access the filters, first remove the dust canister from the vacuum cleaner
body as described in the section "Emptying the Dust Canister".
Grasp the filter assembly and pull up and out to remove.
Grasp the outer filter body and with the other hand, grasp the tabs of the
inner filter and rotate anticlockwise to unlock, then pull up and out.
