How to use

Fill the tank with clean, cool water up to the indicated fill line and add a few drops of fragrance oil if aroma diffusion is desired.

Usage recommendations

Position the diffuser at least several tens of centimeters from walls, fabrics and heat sources to allow even mist distribution and avoid localized dampness.
