Musty or moldy smell from the dehumidifier exhaust air.

Safety: Unplug the unit before cleaning. Avoid inhaling dust or mold; wear a mask and gloves if sensitive.

Steps:

• Clean tank: Remove the water tank and wash it with warm water and mild detergent. Disinfect with a diluted bleach solution (rinse thoroughly afterward).
• Clean filter and coils: Wash the air filter. Use a coil cleaner approved for aluminum fins on the evaporator and condenser, following product instructions.
• Dry interior: After cleaning, run the unit in fan-only mode (if available) for 30–60 minutes to dry internal surfaces.
• Regular maintenance: Empty the tank daily in humid seasons and clean it weekly to prevent odor buildup.
