An elegant, whisper-quiet ultrasonic diffuser from Tisserand that turns water and a few drops of essential oil into a fine, fragrant mist. It suits anyone starting out with aromatherapy at home as well as seasoned oil collectors, and its compact shape sits comfortably on a bedside table, desk or living room shelf.

The reservoir holds 100ml of water; add six to eight drops of your chosen essential oil, switch on, and choose between four to five hours of continuous mist or around nine hours of intermittent diffusion. A soft colour-changing mood light can be left cycling, fixed on one shade or switched off entirely for night-time use. Ultrasonic technology means no heat and no burning, so the character of the oil is preserved. Wipe the reservoir clean between different oils to keep scents true.
