Diffusers are an excellent way to use many Young Living essential oils. There are two primary types of diffusers. Atomizing and therapeutic diffusers dispense 100% essential oil into the air. Water diffusers act similarly to a humidifier, and dispense essential oils in a cool steam. Some diffusers like the Young Living Dewdrop™ combine atomizing and water-based methods into a single product. If you have any questions about the right diffuser for you, please contact me today!
