Remove shrink wrap & stopper from top of Reed Diffuser. Place reeds in vessel & immediately flip reeds over a sink to make sure they are coated in diffuser oil. We suggest starting with 6 reeds in smaller areas, but you can use all reeds for the most scent throw in any room. Flip reeds weekly to keep the reeds from clogging with dust. This will ensure the best scent throw, as well as increase the longevity of your Reed Diffuser. If reeds are no longer working well, replace old reeds with new ones.
