Introducing a professional 30-day battery operated air freshener dispenser and your solution to keeping larger spaces invigoratingly fresh. This dispenser is designed with convenience in mind, it features a smart fan program which works progressively harder as the fragrance weakens in the refill and helps to conserve battery life. Its high-powered fan delivers a more consistent fragrance than aerosol air fresheners whilst also being light sensitive, running at full program when lights are on and at half when lights are off.
