Are you talking about a breather filter in the valve cover that replaces the oil fill. If you are that is to release pressure in the crank case. Usually used if you have a supercharger.
Your talking about the little breather filter on the driver side valve cover, people use a little breather to delete the one from the factory and hose going from that to the cold air intake.
