6. Entretien
Regular cleaning and maintenance are crucial for the longevity and efficient operation of your humidifier.
- Entretien quotidien : Empty any remaining water from the tank and wipe it dry after each use.
- Nettoyage hebdomadaire : Unplug the humidifier. Remove the covers and water tank. Gently clean the inside of the water tank and the ultrasonic vibrating plate with a soft brush or cloth. You can use a mild detergent or a mixture of water and white vinegar to remove any mineral buildup or scale. Rinse thoroughly with clean water.
- Preventing Water Scale: To minimize water scale accumulation, always use purified or distilled water. If tap water is used, scale buildup may occur more frequently, potentially affecting mist output. Periodic maintenance is highly recommended to prevent this.
