What's the difference between aromatherapy machine and humidifier?

The difference between aromatherapy machine and humidifier lies in:

Ordinary humidifier materials themselves will not have oil resistance, and ultrasonic pick is easy to rust and corrode. So you can't use essential oils for aromatherapy.

The aromatherapy machine will not have the above problems, but also take into account the humidification function. Therefore, the aromatherapy humidifier is superior to the traditional humidifier in service life and function.
