Frequently Asked Questions (FAQs)

1. What is the purpose of a carbon canister?

An activated carbon canister is used to capture hydrocarbon vapor emissions from the fuel tank as part of an evaporative emission control system (EVAP).

2. What is a charcoal canister filter?

The Evaporative Control Canister Filter is a charcoal filter that resides inside a storage device that traps fuel vapors from escaping into the atmosphere.

3. How does a carbon filter work?

Carbon filters remove contaminants through adsorption. Adsorption means that contaminants are attracted to the surface of the activated carbon and held to it, much the same way a magnet attracts and holds iron filings. Carbon filters also act as a catalyst to change the chemical composition of some contaminants.
