These water diffusers are great for diffusing our pure fragrance oils. Just fill the tank with water and add 5-10 drops of your favorite oil. Each full tank lasts for 4+ hrs. The fine mist of scent is calming and smells wonderful. We've tried a lot of USB powered water diffusers; this one is our favorite.
We also recommend blending our oils to create your own unique fragrance. If used with our pure fragrance oils, start with only 5 drops because a little goes a long way.
