A filter assembly includes a filter head and a filter cartridge. The filter head includes a filter head coupling surface, a filter head outlet, a filter head inner wall, and a filter head outer wall. The filter head coupling surface defines a filter head opening. The filter head outlet is configured to provide a fluid. The filter head inner wall extends around the filter head outlet. The filter head outer wall extends around the filter head inner wall. The filter head inner wall and the filter head outer wall collectively define a filter head channel. The filter cartridge includes a filter cartridge shell and a filter element. The filter cartridge shell has a filter cartridge coupling surface that is configured to be coupled to the filter head coupling surface. The filter cartridge shell defines a filter cartridge opening.

A fluid filter removal device includes a fluid catch configured to circumscribe an outer surface of a fluid filter, a filter spacer configured to maintain a minimum separation between the outer surface of the fluid filter and an inner surface of the fluid catch when at least a portion of the fluid filter is circumscribed by the fluid catch, and a fluid filter sheath, fixed and hydraulically sealed to the fluid catch proximate the filter exit end of the fluid catch. The fluid filter removal device provides a device and method for removal of oil or fuel filters, and to contain contaminated fluids, on automotive, heavy and other types of equipment to eliminate contamination to the environment as well as contamination to vehicles and users changing a fluid filter.
