The GURUNANDA® Pearl is an easy-to-use, high quality device, it utilizes ultrasonic waves to diffuse the essential oils. The nano-particles of the essential oil together with water form a calming mist that disperses into the air without heating or compromising the benefits of the oil. The soothing lights create the perfect environment to experience the restorative, purifying benefits that aromatherapy can provide. Its sleek, modern design easily complements any home or office space.
