In an exemplary embodiment, the present invention includes at least one reservoir with a delivery mechanism in communication therewith. The delivery mechanism draws an air treatment material from the reservoir and provides the air treatment material in response to a decreased level of active air treatment material or the detection of a malodor. Additionally, the delivery mechanism includes a control system and a detection system. The control system activates the detection system at a timed interval or in response to a change in one or more ambient conditions (e.g., motion, temperature, light, humidity, etc.). Once activated, the detection system samples the environment for either the level of active air treatment material or the quality of the environment.
