How does it do it?:

Yes, it costs more, but it is definitely worth it. It uses your oils much more efficiently, saving you money in the long run, and improves the health and immune function of your entire household. This unit uses high frequency and vibration to convert the oil and the water into a fine soothing mist. The mist is diffused throughout the entire room and the form of the oil is more easily and effectively absorbed by your body. By using a cold mist, the oil is not modified or degraded as happens by using heat to disperse delicate essential oils.
