Happy's Air-Dryr is designed to fight mold and mildew 24 hours a day. The unit has no fans, thermostats, switches, or moving parts - nothing to fail or to cause a spark. Safe for use even in the engine compartment of a boat. The Air-Dryr warms the air in an enclosed space, thus increasing its dew point, so it can hold more moisture. The Air-Dryr is intended for 24 hour operation.
