Frequently Asked Questions (FAQ)
How does an ultrasonic diffuser work?
The diffuser uses ultrasonic vibrations to turn water with essential oils into a fine mist. This cold process preserves all the properties of the oils without heating them.
How much oil should I use?
3–5 drops per session is enough. You can adjust the amount depending on the intensity you want and the size of the room.
Is the diffuser noisy?
No, it is extremely quiet. You can use it in the bedroom at night without any disturbance.
How long does a session last?
With a full tank (400ml), the diffuser runs for up to 10 hours in continuous mode. With the timer, you can set shorter sessions.
Which oils can I use?
Any pure essential oils. We recommend our organic oils: True Lavender for relaxation, Litsea cubeba for energy, Eucalyptus for focus or Swiss Stone Pine for alpine calm.
How do I clean it?
Empty the tank after each use and wipe with a soft cloth. For any residue, use water with a little mild vinegar.
