The Duet Diffuser elevates aromatherapy by utilizing water-free atomizing technology to separate essential oils into a vapor of millions of microparticles. With the Duet Diffuser, you can choose how much essential oil you’d like to use by setting customizable diffusion times, automatic shutoff, and flexible bottle size options in 5 ml, 10 ml, or 15 ml oil bottles. If you would prefer to maximize one particular essential oil, you can connect two bottles of the same oil to both pumps. The timelessly sleek and sophisticated design will add an air of opulence to any space, while its handle makes it easy to bring it with you wherever you go. With the built-in Bluetooth speaker, you can use the Duet Diffuser to add to your atmosphere as you take a bath, sit by the pool, or drift off to sleep.
