Abstract
A two stage air filter adapted for use on an air pump as used in a motor vehicle for emission requirements, has a cylindrical, coarse filter element mounted along one end to a broadside of a thin, rigid baffle plate and a cylindrical, fine filter element mounted along one end to the other broadside of the baffle plate. The baffle plate cooperates with the end bell of the air pump to snappingly retain the filter in the pump and to compressingly hold the fine filter element inside the end bell.
