Abstract
A filter assembly includes a filter cap having a filter chamber defined therein. The filter cap includes a side wall having an opening defined therein. A fluid filter is positioned in the filter chamber. A spring-loaded detent button is movably secured to the filter cap and extends into the filter chamber. When the detent button is depressed by a user, the end of the detent button positioned in the filter chamber contacts the fluid filter thereby releasing the fluid filter from the filter cap. An associated method for replacing a fluid filter is also disclosed.
