Our Reed Diffusers are great for adding fragrance to a room,  they work best in smaller areas. The room temperature will affect the scent throw, so the warmer the the room the better the scent throw.  Our Reed Diffusers are 100ml and last approximately 2/3 months. If after a while you notice that your scent throw has reduced, your reeds may be clogged and it may be time to buy replacement reeds. Our Fibre Diffuser Reeds are superior quality to traditional rattan reeds. Our Reeds have been designed to clog less and have a dense and vibrant appearance, even when dry.  The fragrance will be diffused along the entire length of the reed for a consistant fragrance throw and will require less flipping than other reeds. Our fibre reeds have a porous structure that provides a controlled rate of fragrance release throughout the life-span of your diffuser.
