People who are just starting their journey into diffusers and essential oils frequently ask, "How does an ultrasonic diffuser work? How are they different from any other essential oil diffusers?"
These are great questions. An ultrasonic diffuser is a device that uses ultrasonic vibrations to disperse essential oils into the air. Ultrasonic sound waves operate at a high frequency so the human hear is unable to hear the sound that they produce. The essential oil and water mixture is vibrated, which separates the water particles, the negatively charged particles that result are lighter than air and creates the "mist" that you can see rising out of the top of the ultrasonic diffuser. Most ultrasonic diffusers simply plug into standard power outlets
