Latest developments in oil filtration are moving from the conventional spin-on filter to a filter housing with an exchangeable filter element. This new filter element is designed almost entirely of the actual filter media. The so-called metal-free element can be disposed of easily and completely through incineration and, therefore, provides a great environmental and economical solution.In this paper two principles of metal-free elements are compared using a life cycle assessment. Analysis shows that in all categories the thermoset-cured design has advantages versus the nylon 6 injection molded version, even if 100% post consumer nylon is used.
