Create a healthy and relaxing aromatic environment in your spa, salon, business or home with Biossentials 100% natural essential oils and our beautiful bamboo and ceramic Ultrasonic Aroma Diffuser. The heat-free aromatherapy diffuser uses ultrasonic vibrations (up to 2.5 million vibrations per second) to instantly break down essential oils and water into tiny micro-particles dispersing them into the air in a fine aromatic mist. The mist penetrates the air more effectively, is absorbed more easily and optimises the therapeutic benefits of Biossentials pure essential oils.
