Doulton®-designed QT Filter is a quick-change, auto shut-off, environmentally friendly unit ideal for water cooler and domestic drinking water applications. A quarter-turn action to remove the filter body from the head automatically switches off the water, significantly reducing the required change-out time. The housing design features an integral mounting bracket incorporated into the head; push-fit connections in the head, available in either 0.25- or 0.375-inch (6.35- or 9.52-mm) sizes, ensure rapid connection. The full range of Doulton ceramic filters are available for use with the housing, including the Ultracarb® grade.
