Newgrange - Ultrasonic Natural Oil Diffuser ~ Unicorn Lustre. An ultrasonic essential oil diffuser uses electricity to disperse essential oils into the air.. These diffusers retain the full benefit of the diffused essential oil because they do not utilise heat in the production of vapour. Heat can have a negative effect on essential oils.. Using an ultrasonic natural oil diffuser in your home can completely change the ambience and help you to feel at ease while improving overall sleep patterns and wellbeing.
