Abstract
An improved fluid filter is provided that has a rigid apertured center tube which is attached to a fluid outlet. Once the center tube assembly is secured to the fluid outlet, a tubular filter element is replaceably secured around the center tube. By incorporating a rigid center tube, the tubular filter element can be constructed so that it does not require a self contained supporting structure. Thus, by eliminating an integral supporting structure, the filter element can be made solely of combustable materials, aiding in the disposal of used filter elements.
