How important is a charcoal canister?

Function of a Charcoal Canister A charcoal canister has an important job to do in a vehicle. Its job is to take all the harmful carbon emissions generated by the engine of the car and stop them from getting let out into the earth’s atmosphere.

How do you clean a purge canister?
