Humidifying & Ultrasonic Diffusers

An ultrasonic diffuser utilizes electronic frequencies to cause a small disk under the surface of a liquid (usually water) to vibrate at a very fast rate. These ultrasonic vibrations break the essential oil into tiny microparticles, dispersing the oil in a fine mist. These tiny particles are more easily absorbed by the lungs for a greater therapeutic effect on the body, mind, and spirit.
