5. Maintenance
Regular cleaning helps maintain the diffuser's performance and extends its lifespan.
- Empty Water: Before cleaning, unplug the diffuser and empty any remaining water from the tank.
- Wipe Tank: Use a soft cloth or sponge to wipe the inside of the water tank. For stubborn residue, a small amount of mild dish soap can be used, followed by thorough rinsing.
- Clean Mist Disc: After 7 uses or 7 days, use a cotton swab dipped in clean water or white vinegar to gently scrub the ultrasonic mist disc located at the bottom center of the water tank. This removes mineral buildup that can affect mist output.
- Dry Thoroughly: Ensure all parts are completely dry before reassembling or storing the diffuser.
- External Cleaning: Wipe the exterior of the diffuser with a soft, damp cloth.
Note: Do not immerse the base unit in water. Avoid getting water into the air outlet channel, as this can damage the internal components.
