Abstract: An easily serviceable liquid filter assembly having a housing with a drain to provide draining of fluid (e.g., liquid) from the housing. The filter assembly has a fluid inlet to receive dirty fluid into the housing, a fluid outlet to expel filtered fluid from the housing, and a drain, when open, to expel unfiltered (dirty) fluid from the housing. By removing a cover from the housing, the filter element opens the drain so that all fluid in the housing can be directly collected or can flow into the oil pan to be collected with the fluid present in the pan. All fluid, now in the drain pan, can be drained and collected in a disposable container such as a plastic pouch, which can be recycled. The filter element can be removed from the housing via the removed cover.
