Simply put, a reed diffuser is an ancient system for introducing fragrances into the air.
It starts with a bottle of scented essential oil. The bottle is opened, and long bamboo reeds are placed inside and allowed to protrude from the top of the container. Because bamboo is porous, the reeds draw the essential oil upward and out of the bottle — where it “diffuses” or evaporates into the air. The result is a gentle, continuous release of fragrance that can last up to six months (depending on the amount of oil used).
