Where it is located It is located under the top cover, usually as a small removable tray or a housing with an absorbent pad.
It is not connected to the water tank: the fragrance is diffused by evaporation, not by mist.
What to insert Only essential oils or room fragrances.
Never water, detergents, alcohol or liquid mixtures not intended for aromatherapy.
How to use it step by step Open the top lid of the humidifier. Look for the small tray/aroma pad. Pull out the holder (if removable). Add 2-3 drops of essential oil to the pad. Reinsert the holder and close the lid. Switch on the humidifier: the fragrance will be gradually diffused.
Frequency of use You can add new drops when the fragrance is no longer noticeable. If you change fragrance, wash or replace the pad to avoid mixing.
Important warnings Never put essential oils in the water tank: they can damage the ultrasound and plastic. Only use good quality oils to avoid residue. Do not overdo the drops: too many oils can saturate the pad and reduce diffusion.
