2. Gently remove the dust using a small vacuum designed for computers or a very soft brush (such as
a paintbrush).
Note: You can remove the air filter so you can clean both sides of it. Do not rinse the air filter in
water, or use any detergent or solvent to clean it.
Caution: Do not use canned air, or the gases may leave a residue.
3. If dust is difficult to remove or the air filter is damaged, replace the air filter.
