Abstract
A useful life indicator is provided to display an indication of the remaining useful life of an associated product such as an impregnated substrate of an air treatment chemical dispenser. The cue is preferably a well having 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. The cue may also be used in connection with monitoring other products such as perishable products.
