This amazing piece is a nebulizing "negative ion" diffuser which uses straight essential oil without the use of water. It has two speeds, "high and low" and 7 color changing lights. It is virtually silent which is unusual for a unit of this type. It is very easy to fill. Simply remove the top glass lid and drop between 5-30 drops of your favorite essential oil in. This will cover about 400 sq ft
This unit will run for 2 mins ON and 1 min OFF. This occurs for 2 hours straight and then the unit shuts itself down. The Light will remain on until it is powered off.
