CAUTION: Because the air filter is rather long, you should hold its front end with
one hand, and bear its weight by putting another hand underneath it when sliding
the air filter out of the chassis.
3 Rather than taking the air filter mesh out, directly wash the air filter after removing
it from the chassis, allow it to air dry, and insert it back into the chassis.
