Convenient air freshener dispenser with a high-powered fan that moves fragrance further than a passive system. Easy to refill, it's the only air freshener dispenser that uses the fragranced cover as the refill. The smart system releases consistent fragrance 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 alerts when it's time to change the cover and battery after 30 days. Material(s): Plastic; Color(s): White; Height: 1.5"; Width: 4.75".
