Humidifier has a strong musty or moldy smell

Safety: Unplug the humidifier before cleaning. Avoid inhaling mold spores; consider wearing a mask.

Steps:

• Empty the water tank and base completely.
• Wash the tank with warm soapy water, then disinfect with a solution of white vinegar or a manufacturer-approved disinfectant. Rinse thoroughly.
• Clean the base, transducer area, and any removable parts with vinegar to remove biofilm.
• For evaporative models, replace the wick filter if it is discolored or slimy.
• Allow all parts to dry fully before reassembly. Use fresh water and clean the unit regularly to prevent recurrence.
