Daily: Empty and refill the tank with fresh water if not used for over 24 hours.
Weekly Cleaning:

- Clean: Wash all parts with mild dish soap and lukewarm water. Use a soft brush for the tank interior and transducer (silver disk).
- Rinse thoroughly to remove all soap residue.
- Dry all parts completely with a soft cloth before reassembly.
Descaling (Monthly or as needed):
- Mix white vinegar and water (1:1) in the tank. Let sit for 15-20 minutes.
- Gently scrub the transducer and tank interior with a soft brush.
- Empty the solution and rinse multiple times with clean water until vinegar smell is gone.

CAUTION! Never submerge the base unit in water. Do not use abrasive cleaners, bleach, or harsh chemicals.

Using Essential Oils

The unit includes a dedicated aroma pad/tray for essential oils.

Ensure the humidifier is turned off and unplugged.
Pull out the essential oil tray located near the mist outlet.
Add 3-5 drops of your preferred 100% pure essential oil onto the provided cotton pad or directly into the tray.
Reinsert the tray securely.
Operate the humidifier as normal. The mist will carry the aroma.

WARNING! Do not add oils directly into the water tank, as this can damage the unit and void the warranty. Clean the tray regularly to prevent oil residue buildup.
