To provide a method and apparatus for replacing a used filter cartridge in a filter assembly provided with a latch.
A filter cartridge 20 and a latch release 40 independently of each other are used. The filter cartridge comprises an end cap 56 having an opposed center hole. The filter cartridge is inserted into a filter assembly housing 12. In this housing, a latch 36 prevents a cover from being provided on the filter assembly until the latch function is released. The latch release is arranged relative to the filter cartridge to cooperate with the latch to enable the cover to be reattached to the filter assembly housing. The latch release includes tabs that align with features of the latch and extend through the central holes to cooperate with the latch. The latch release is removably secured to the cover and the filter cartridge.
