If you take a good look at this design you’ll instantly see why we had to add it to our list. This is one of the most stylish car essential oil diffusers and we just love the wood effect combined with the color-changing body. Not only does this product look great but it also works hard to remove unwanted odors and promises to leave behind a pleasant smell that lingers for a long time. Much like the others, this diffuser works by using silent ultrasound vibrations to create a mist in the space where it occupies. This product works as an essential oil diffuser and humidifier, adding moisture to the air for health benefits. The mist is cool so this is a safe item to use around children and animals. The color sequences can be adjusted to stay on one chosen color or cycle through the color spectrum.
