Operating Instructions

Maintenance and Cleaning
Regular cleaning helps maintain the efficiency and longevity of your humidifier.
- Daily Maintenance:
- Unplug the humidifier before any cleaning.
- Empty any remaining water from the tank and base.
- Wipe the tank and base with a clean, damp cloth.
- Weekly Cleaning:
- Clean the Water Tank: Remove the water tank. Unscrew the cap and rinse the inside thoroughly with clean water. You can use a soft brush to clean any residue.
- Clean the Base Unit: Gently wipe the inside of the base unit, especially around the ultrasonic vibrator (the small disc in the center), with a soft cloth. Do not use abrasive cleaners or scrub the vibrator. If mineral deposits are present, you can use a solution of white vinegar and water (1:1 ratio) to soak the area for 10-15 minutes, then gently wipe clean. Rinse thoroughly with clean water.
- Clean the Mist Output Nozzle: Ensure the nozzle is free from any blockages.
- Storage: When not in use for an extended period, clean the humidifier thoroughly, ensure all parts are dry, and store it in a cool, dry place.
Note: No special water is required for operation, but using distilled water can help reduce mineral buildup.
