3. Aroma Function (Optional)
To use essential oils, locate the small aroma sponge tray, typically found on the side or back of the base unit. Add a few drops of your preferred essential oil onto the sponge. Do not add essential oils directly into the water tank or base reservoir, as this can damage the unit and void the warranty.

2. Weekly Cleaning (or more often with hard water)
- Descaling the Base Reservoir: Mix 1 teaspoon of white vinegar with 1 cup of water. Pour the solution into the base reservoir and let it soak for 20-30 minutes. Gently scrub the ultrasonic transducer and other surfaces with a soft brush or cloth to remove mineral buildup. Rinse thoroughly with clean water.
- Cleaning the Water Tank: Pour a small amount of the vinegar solution into the water tank. Swish it around to coat all inner surfaces. Let it soak for 20-30 minutes. Use a soft brush to clean the inside of the tank, especially around the opening. Rinse thoroughly. The wide opening facilitates easy cleaning.
- Cleaning the Filter Element: If your model includes a filter element, rinse it under cool running water. Replace if heavily soiled or as recommended by the manufacturer.
