Reed diffuser works on the principle of capillary action, when reeds which are porous and excellent for diffusion are partially immersed in a bottle of fragrance oil, fragrance travels up the reeds and gently permeates the room.   This process gets the best out of your essential oils by releasing their full aromatic and therapeutic properties, thanks to cold diffusion which maintains the delicate balance of the oil's chemical structure. A 24hr aromatic experience. No fIre, No ash, truly maintenance-free
