Designed to bring you optimum relaxation and therapeutic benefits, the advanced Aroma Lite Diffuser features four mist output settings and real-time atomization technology. It can create an ultra-fine mist (1–3 microns) for maximum essential oil diffusion. With its large reservoir, you can customize the diffusion of dōTERRA single oils, oil blends, or your own blends for up to eight hours (depending on the setting). Small and compact, the diffuser silently purifies and humidifies the air and has an optional night light, making it perfect for night time use and for traveling.
