Ultrasonic Diffusers
Ultrasonic diffusers work in a similar way to nebulizing diffusers by creating a fine mist. The difference is that ultrasonic diffusers use water and essential oils to create a cool mist of water/oils that releases in to the air. They double as a humidifier, so they are beneficial in winter, but they don’t put out as strong of a concentration of essential oils since they also use water. It is not recommended to use citrus essential oils with this type of diffuser as they can cause the parts to erode.
Pros:
Less expensive than nebulizing diffusers
Doubles as a humidifier (beneficial in cold months)
Many options to choose from
 
Cons:
Can’t use citrus essential oils
Need water to operate
Must be cleaned occasionally
Not as effective as nebulizing diffusers
