A fan can only do so much to combat mold and dampness in the home. It moves the air and can help stagnant, damp areas dry faster, but it does not remove moisture from the home. The RIVM puts it this way: a fan does not ventilate; it only moves air. You also need ventilation or a dehumidifier.
What a fan can and cannot do about dampness
The RIVM explains that an air conditioner or fan does not ventilate, but only moves air. True ventilation means bringing in fresh outdoor air through a vent or window. A fan can help refresh the layer of air above a wet surface, so that evaporation happens faster. However, the moisture remains in the room until you remove it.
Where mold develops
According to Milieu Centraal, mold grows in damp areas such as bathrooms and bedrooms and indicates moisture problems and insufficient fresh air. Recurring or extensive mold may be caused by a leak, rising damp, cold bridges, or inadequate ventilation; see mold and dampness in the home. Mold can be harmful to your respiratory tract, so it is wise to address the cause. If mold reappears in several places or the cause is unclear, consult a professional.
Using a fan effectively against damp areas
After showering: open the window for 20 to 30 minutes, as Milieu Centraal advises in their tips for ventilation. A fan can help wet tiles dry faster.
For clothes drying indoors: direct the airflow at the drying rack and ventilate at the same time. Also read how a fan can help clothes dry faster.
Behind furniture and in corners: a gentle airflow prevents air from becoming stagnant. Also read why it sometimes smells musty in a wardrobe.
Together with a dehumidifier: this works well in an enclosed space; see using a fan and dehumidifier at the same time.
Direct answer: a fan only moves air; it helps damp areas dry faster, but you must remove moisture using ventilation or a dehumidifier.
