Abstract
A filter system including a designated filter cartridge including a geometric projection therein and a filter cartridge housing. The filter cartridge housing including a valve that controls fluid flow out of the filter system, a filter cartridge housing, and a filter cartridge housing cover. The valve may include an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the valve, and the valve may be configured to attach to the filter cartridge housing cover by a snap fit connection.
Claims20
A filter system comprising:
