Understanding Ultrasonic Humidifiers:
Ultrasonic humidifiers use high-frequency sound vibrations to produce a fine mist that is then dispersed into the air. This process is quiet and efficient. It is important to use purified or distilled water to minimize mineral dust (white dust) accumulation in your room and on the unit.

Maintenance
Regular cleaning is crucial for optimal performance and hygiene. It is recommended to clean the humidifier every 2-3 weeks, especially if used regularly.
- Daily Maintenance:
- Empty and rinse the water tank and base with fresh water.
- Allow all parts to air dry before refilling.
- Weekly Cleaning:
- Unplug the unit.
- Remove the water tank and empty any remaining water.
- Fill the base with 1 cup of white vinegar and let it soak for 20 minutes to loosen mineral buildup.
- Use a soft brush or cloth to clean the inside of the tank and the nebulizer in the base.
- Rinse all components thoroughly with clean water until the vinegar smell is gone.
- Allow all parts to air dry completely before reassembly.
- Demineralization Cartridge Replacement:
The demineralization cartridge helps reduce mineral dust. Replace the cartridge every 6 months or more frequently depending on water hardness and usage. Refer to the specific instructions provided with your replacement cartridge.
