Abstract
A device, such as a home air freshener, which is mounted to the main positive pressure air duct of a forced air furnace heating system and or a central air conditioning system by which an outside agent, such as an air freshener, is introduced into the air duct for the distribution to areas served by the air duct system. By means of a sub-duct properly positioned in the path of the airflow, the device can create a low pressure area in the sub-duct which will draw and distribute the air freshener and thus operate with out means of outside pressure, power, or moving parts.
