The Nanum car diffuser works both as an air humidifier and aroma diffuser. Fill the 12v diffuser with water and 1 to 2 drops of essential oil. Then, plug it into your vehicle's DC jack. Swivel the unit in the direction you want it to spray. The diffuser emits a cool mist that adds moisture to the air. It is equipped with 2-hour automatic power off technology. It's currently $8.99.
