Use a “pozidrive” screwdriver to unscrew the screw on the grid cover.
Remove the filter pad from inside the grid cover. Wash the filter pad

the filter, by running clean water through it, and let it dry

Place the clean, thoroughly dry, filter pad inside the grid cover.
Screw the grid cover firmly back in place over the ventilation unit.
