Abstract
Disclosed are devices for dispensing air treatment chemicals. There is a substrate bearing a first volatile air treatment chemical that is capable of being dispensed from the substrate when the substrate is heated, and an indicator unit holding a volatile indicator chemical separate from the first volatile air treatment chemical such that the volatile indicator chemical is capable of being dispensed from the unit when the unit is heated. The extent of dispensing of the first volatile air treatment chemical can be indicated by a visible cue whose appearance results from the dispensing of the volatile indicator chemical. In one form the unit also holds a second air treatment chemical. In another the indicator unit is a replaceable cartridge positionable more remote from the heater than the substrate.
