remove dust drawn into the router by the blower module. You should examine the
air filters once a month (or more often in dusty environments). If the filter appears
dirty, you can either vacuum or replace it. If the filter appears worn or torn,
dispose of it in a responsible manner and install a replacement air filter.

an air filters by pulling the small tab on the edge of the filters (see Figure5-2).
