Summary:An air treatment control device has a useful life indicator of an air treatment chemical dispenser. The indicator device has a well with a volatile indicator material positioned therein. The well's cavity is configured to achieve clumping of the remaining indicator material as some volatizes due to capillary attraction. This presents a shrinking display that can be coordinated with the level of use of the air treatment chemical dispenser.
