If you love essential oils and you drive a lot, have a long commute, carpool or like to road trip you’re going to flip over this mini car diffuser. There are a lot of diffusers on the market that are sold to be used “in the car” but they almost all work by using heat (which is terrible for the therapeutic properties of essential oils.) This little guy actually uses water and is a TRUE diffuser! You’ll wonder how you ever lived without it! Simply plug the diffuser into your car’s cigarette lighter with 100ml water and 2 drops of your favorite essential oil! Touch activated on/off with 2 diffusing settings. Use without essential oils (water only) as a humidifier in the winter. These also make a great accessory for your motorhome or RV The top will articulate to accommodate all makes and models of car. Do not keep plugged in or running when water is empty. Do not let water freeze in diffuser overnight in the winter.
