The assembly includes an outer metal container, an inner structure of filter media and an inner metal container for insertion into an open end of the outer metal container and over the inner structure of the filter media. The inner metal container has an end exposed at the open end of the outer metal container and an end structure closing the end of the outer metal container opposite the end receiving the inner metal container. An end structure is also provide for closing the exposed end of the inner container. The end structures include at least one layer of an air permeable material that permits air flow through said layer and through the inner structure of filter media while retaining the filter media within the canister assembly. The inner structure of filter media is longer than the combined length of the metal containers when they are telescoped together to compact the filter media within the telescoped containers.
