Reed Diffusers are a great way to add constant fragrance to your home. The diffuser reeds soak up the fragrance oil and disperse the scent into the air. They last until all the fragrance oil evaporates. Diffusers work really well in places where you always want it to smell nice but can't keep an eye on a candle. Some great locations are in a foyer so you and your guests are greeted with a beautiful fragrance when you walk in, or in a powder room, closet or basement where you always want it to smell nice but you can't always keep an eye on a candle.
