ABSTRACT:
A filter element for use with a forced air central heating and cooling system includes a liquid reservoir that is fluidically connected to a plurality of wick elements that are located in the filter media of the filter element. A movable plate includes wick portions and portions that are impervious to fluid, and is moved from a position fully connecting the wick elements to the fluid in the fluid reservoir to a position preventing such fluid connection to control the amount of scent placed into the system.
