This Essential Oil Diffuser is a compact and portable device that creates olfactory (smelling) sensory stimuli, which can calm individuals in proximity to it. It also functions as a humidifier and night light, with 7 different colors. It has an auto shut off feature and features two misting modes: the first is continuous, misting until the water is empty (which takes approximately 6 hours); the second is an intermittent mist mode, which mists every 6 seconds until the water is empty (which takes approximately 12 hours). This device may be helpful for individuals who need calming sensory input. It measures approximately 3.6-inches by 3.6-inches by 6-inches and weighs approximately 1-pound.
