Our fresh dispenser has an innovative smart program that ensures equal fragrance release over 30 days. Contains a light sensor to conserve battery life so the unit only works when the room is in use. The smart chip controls the programming so the fan runs sparingly in week 1 and gradually turns more frequently over the 4 weeks, helping release the same amount of air freshener daily over 30-day

Key Features:

• Light-activated only runs when the lights are on
• Requires 1 C alkaline battery (included with each refill)
• The green light blinks when the fan is running, the red light blinks when the battery is low, or on day 30
• Word replace flashes on day 30, audible been day 33
