An air freshener device has a chamber containing a fragrant material pivotal with respect to a back opening in the a plate. A perimeter notch is formed in an intermediate brace and a front dial plate so that a scale on the back plate is visible. A single cartridge has a pair of scent chambers coupled together and disposed adjacent one another in a side-by-side relationship, and formed as a pair of separate and discrete vessels in a plastic sheet separated by a divider and covered by a permeable membrane. Each of the pair of vessels contains a fragrant material with a fragrance that can permeate through the permeable membrane over time.
