When the unit is on, the mist decreases until it is no longer visible. The Nano atomizer adjusts the size of the essential oil molecules produced to minimise oil output. In addition, the diffusion is done directly from the essential oil bottle, without adding water. You will only perceive a mist from time to time (the frequency depends on the chosen diffusion mode). There is no continuous steam as there is with an ultrasonic nebulizer that works with water (or hydrosol) and essential oil.
Make sure the unit is fully charged for optimal operation. Use the DC5V cable, the USB interface of a computer, the USB interface of a mobile charger or the USB interface of a car charger. When the unit is charging, the red LED light will flash. It stops flashing when charging is complete.
To clean the spray nozzle, fill the bottle with alcohol and run the unit for 2 hours. Then let the empty bottle air dry for about 10 hours to allow the residual odor to dissipate.
