Ultrasonic diffusers are better than steam and heat diffusers and offer a few other benefits like being easy to clean and requiring little power.

What is the difference between an ultrasonic diffuser and a regular diffuser?

While ultrasonic diffusers rely on water to evaporate essential oils, nebulizing diffusers rely on an air-jet pump to blow the air across the top of the tube. This creates a vacuum to lift the fine particles on the surface of essential oils and disperse these tiny droplets into the air.

What are the benefits of ultrasonic diffusers?

An ultrasonic diffuser also produces negative ions, which help to freshen the air by removing dust particles. These negative ions bind to dust particles, making them heavier and dropping them to the ground, which leaves your air feeling refreshed.
