Does mold go away with a dehumidifier?

Mold stays “dormant” in the air or on surfaces even when there's no excess moisture to help it grow. If the humidity in a room increases, mold will start growing in patches on walls, clothes, and more. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity.
