I believe what you are describing is the carbon canister unit. Part of the EVAP system, it's the same on a lot of Fords.

The carbon filter is supposed to last the life of the car, but the EVAP canister itself may need to be serviced if it develops a leak, and you'll see a trouble code if that ever happens.
