Method and apparatus for dispensing a scent into the air

An air freshening apparatus comprising:

• an outer cylindrical member comprising a first closed end, a second open end, and at least one rectangular shaped longitudinal opening passing through said outer cylindrical member;
• an inner cylindrical member comprising a first closed end, a second open end, and at least one step-shaped longitudinal opening passing through said inner cylindrical member, wherein said inner cylindrical member fits concentrically within said outer cylindrical member forming a frictional interface between said inner and outer cylindrical members, and where said inner cylindrical member is greater in length than said outer cylindrical member such that said open end of said inner cylindrical member extends beyond said open end of said outer cylindrical member;
• at least two replaceable scent filled media containers which are cylindrical in shape and concentrically retained within said inner cylindrical member;
• and
• means for aligning said at least one step-shaped opening in said inner cylindrical member with said at least one rectangular opening of said outer cylindrical member such that said two replaceable scent filled media containers may be exposed to an air interface either selectively or simultaneously.
