  1. Before cleaning the unit, turn the power off and make sure the adapter is unplugged from the diffuser and outlet.
  2. Remove the outer cover from the base. Next, remove the inner cover.
  3. Carefully pour any remaining water and essential oil out of the reservoir, from the drain side, opposite the air outlet. Be sure not to empty the reservoir near the air outlet in order to avoid malfunction.

To Clean the Surface

Clean the surface of your diffuser with a clean, damp, soft cloth as often as needed.

To Clean the Reservoir and Ultrasonic Membrane

We recommend wiping the reservoir with a clean, damp, soft cloth at least once every 2 weeks.

NOTE: Depending on your usage, and the amount of essential oil you use, you may want to clean the reservoir and ultrasonic membrane more frequently for best performance.

For the most thorough clean, pour a 50/50 mixture of vinegar and water into the reservoir, then soak for five minutes. Brush reservoir walls, base, and ultrasonic membrane clean with a soft-bristle brush (not included) and rinse. NEVER touch the
ultrasonic membrane with your fingers, as the natural oils in skin can damage the membrane.

Clean the membrane once every two to three weeks, depending on your usage.

Clean and dry the unit before extended periods of inactivity.
