Davis Air-Dryr Marine Dehumidifier

A boat closed up for a week grows mildew, and the smell is the least of it. The Air-Dryr works by gently warming the air in a closed space so natural convection keeps it moving and moisture does not condense on cold surfaces. There is no fan, no switch and no thermostat, which means nothing to fail and nothing to make noise or a spark.

• Two sizes: model 1459 handles up to 500 cubic feet at 0.6 amps and 70 watts; model 1458 handles up to 1000 cubic feet at 1.1 amps and 130 watts.
• Designed to run 24 hours a day on a standard 110 to 120 volt outlet.
• Slim, low profile beige polycarbonate housing that sits on the sole and does not tip easily.
• Silent, safe to the touch, with no moving parts and no components that spark.
• One year manufacturer warranty.

Place it low in the space. Warm air rises on its own, so putting it on a berth or a shelf works against the way the unit is meant to circulate.
