The Diptyque electric diffuser uses contemporary, mobile technology to diffuse selected interior fragrances representing all the scent families (Ambre, Baies, Figuier, 34, Feu de Bois).Each of the capsules is note-perfect. You simply slide one into the little high-tech machine then switch it on by pressing the top, and let it diffuse the scent 3 times during a 1-hour cycle (10 minutes active, 10 minutes rest).Repeat as often as you wish. The electric diffuser is recommended for scenting relatively large spaces (approx. 30m²). Capsule sold separately.
