Abstract
Devices dispenser air treatment chemicals in response to heat generated by a candle. Heat transfer elements carry flame heat to an impregnated substrate that is positioned mostly or entirely below the candle. The air treatment chemical vapors are kept away from prolonged direct exposure to flame heat, thereby reducing heat degradation of the active. The candle automatically adjusts heat transfer rates to correct for decreasing amounts of active on the substrate as the substrate sears being used up.
