The present invention describes a method and apparatus for preventing and/or removing the condensation from the inside of the windshield, side windows, and rear windows of an automobile, truck, boat, aircraft, tractor, train, military vehicle, or similar vehicle cabin to provide clear visibility for the occupants. In addition to condensation removal, the system provides added benefits of enhanced cooling effects and comfort for the occupants by lowering the cabin humidity, and the operation and efficiency of the air-conditioning system is also improved due to the reduction in the humidity. A desiccant wheel system is used to perform the dehumidification. Automatic and manual controls prevent condensation from forming and may also be set to maintain a lower humidity level for the occupant comfort and cooling efficiency. The desiccant wheel is regenerated by hot air from a heat exchanger or other heat source using excess engine heat. An air filter is provided at the air intake for both the cabin air and hot air to prevent foreign matter from entering the system. The dehumidification is performed without introducing outside air into the cabin.
