The present invention supports an airflow register accessory comprising an accessory having an outer and an inner surface and defining vents, a fastening mechanism located on the inner surface of the accessory, and a scented component located on the inner surface adjacent and accessorizing the vents. In a preferred embodiment, the accessory may be easily attached to and detached from the room-facing surface of an airflow register. Upon air flow from an HVAC system through the airflow register and airflow register accessory, a pleasant scent may be imparted to the room via release of scent from the scented component.
