Naturactive's TERRAZZO essential oil diffuser uses ultrasonic technology with added water to project the essential oils into the air in the form of fine droplets. This process has the advantage of preserving all the qualities of the essential oils. It operates completely silently and produces a beautiful visual effect in seven adjustable colours. It's easy to use, and features an automatic shut-off. In terms of materials, the cover is made from bamboo fibre and the base from resin (composed of fragments of stone, coloured marble and polished cement to give a mineral, glittery look). It has a diffusion capacity of up to 120 m2.
