- Regular Cleaning: It is essential to clean your humidifier regularly to prevent the buildup of mold and bacteria. Use a mixture of vinegar and water to wipe down the tank and base, ensuring that all components are free of grime.

- Store Properly During Off-Season: If you plan to store your humidifier for an extended period, ensure it is thoroughly cleaned and dried before putting it away. Proper storage prevents the growth of mold and bacteria during the months of non-use.
