Convenient air freshener dispenser with a motor-driven fan that moves fragrance further than a typical passive system. Powerful enough to freshen even your largest spaces. Easy to refill air freshener dispenser is the only air freshener dispenser that uses the fragranced cover of the dispenser as the air freshener refill itself. The smart system releases approximately the same amount of air freshener daily over 30 days by turning the fan sparingly in week one, and gradually turning it more frequently until week four when the fan runs constantly. The smart dispenser comes with a light that alerts you to change your cover after 30 days, and begins counting down another 30 days once you change the cover!
