Because heat is not used, the oils are not chemically changed or broken down. This makes nebulizers superb for clinical studies. Nebulizers are incredibly efficient. A much larger percentage of the essential oil is diffused. They will save you money by using less oils.
Nebulizers are safe to leave unattended, and some have timed cycles or flow adjusting.
This greatly expands the range of environments that they can be used in. Nebulizers can fill a much larger area than flame or electric heat diffusers. Make any shower feel like being in a fragrant spa . Place 2 to 5 drops in the shower or on the shower walls before turning on the water. The steam will carry the essential oils, bathing your entire body in aromas.
