contains carbon or oil: Soak filter in detergent for 15 minutes, wash and
rinse with water and let it air dry. When filter has completely dried, use
a light to check for damage.

Replace the air filter yearly,
or after every 6th cleaning, whichever comes first.
Do not touch secondary (inner) filter unless you are replacing it. If dirt
is found on the inter filter replace both filters immediately.
