Car Electric Diffuser helps deodorize and freshen your car. This diffuser is perfect for smokers and for those who want to fragrance their cars naturally without the use of chemicals. Simply fill the oil canister with aroma oil, insert the absorbing stick, and plug the diffuser into the lighter/adaptor outlet. Because you can fill the canister with much more oil then with the traditional absorbant pads, the scent and oil last 3x longer! Within minutes you car will be refreshed and smelling great!
