Ourfresh Dispenser, 5.34 X 1.6 X 5.34, White

Innovative smart programming ensures an equal fragrance release over 30 days. Contains a light sensor to conserve battery lift 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 week period, helping release the same amount of fragrance over 30 days.
