Wild Essentials home diffusers are the perfect solution to diffuse in any size room. Our 500ml diffuser has a dark wood finish with a branches design carved into the side of the shell, and moons and stars on the top. Also comes with a remote control, uses AC power and is an aromatherapy/essential oil diffuser, humidifier, vaporizer, air freshener and multicolored nightlight - all in one! Simply fill the water chamber with up to 700ml of water (about 3 cups) and a few drops of your favorite essential oil or fragrance for up to 20 hours of use! Our home diffuser has a very quiet (under 25dB) operating cycle and uses 2.4 MHZ ultrasonic frequency technology.
