PureGuardian SPA101WCA Ultrasonic Cool Mist Aromatherapy Essential Oil Diffuser with Color-Changing Light

The PureGuardian Aromatherapy Essential Oil Diffuser uses ultrasonic humidifier technology. Simply add just a few drops of essential oils to the water, and the ultrafine mist will quickly and continuously fill the room with the natural oil aroma. The diffuser is quiet and won't disturb you when you're sleeping. The optional color-changing light creates a soothing glow. It's lightweight and compact, making it great to put on small night stands. The 100ml water reservoir is BPA free and treated with Silver Clean Protection, which fights the growth of mold on the surface of the tank.
