4. Use a small vacuum cleaner designed for computers
and other office equipment to clean the filters. Or
use a soft brush (such as a clean artist’s paintbrush)

broken, contact your place of purchase to replace
them.
5. Replace the filters then press the covers back until
they click into place.
If the covers are not correctly seated in place, you
