   • Rinse thoroughly with clean water and air dry completely before reassembly.
3. Descaling (Monthly or as needed):

   • Gently scrub the interior with a soft brush, then rinse multiple times with clean water until vinegar smell is gone.
4. Filter Care: The Classic 300S uses a demineralization filter (optional). Replace filter every 3-6 months or as indicated by the app.

CAUTION! Never use abrasive cleaners, bleach, or harsh chemicals. Do not immerse the base in water. Ensure all parts are completely dry before use.

Using Essential Oils

The humidifier includes a dedicated essential oil tray. Do not add oils directly to the water tank.

1. Ensure the humidifier is off and unplugged.

4. Slide the tray back into place.
