Dehumidifiers remove moisture through the process of evaporation. You buy a dehumidifier that is appropriate for the relative humidity (how much moisture is in the air) in your particular climate. For example, if you live in a dry, cold climate and your relative humidity is higher than 50 percent, you need to buy a dehumidifier that is capable of removing at least 50 percent moisture from the air. Refrigeration units referred to as air conditioners remove moisture from the air; they have a different name for the same function.
Dehumidifiers are sold under a variety of labels: electronic — electronic models have a built-in thermostat to control the speed of operation; gas — models that operate with a gas line and gas appliance; and ductless — models for air conditioning units. If you notice, your dehumidifier is ductless, it runs outside of your ductwork or it is dryer-specific (which means you have to manually add moisture, or dehumidify the air, whenever the unit runs).
Electric models must be connected to an electrical outlet. Some models can be used to mix cool outside air with warm inside air, which is known as butterfly or forced-air ventilation. If you choose this mode, you will need to open your exterior windows to allow in fresh air to mix with the air inside your building.
Dehumidifiers remove moisture from the air via evaporative processes that consume energy in the form of electricity. A dehumidifier would be an easy part of your home energy efficiency efforts. The Energy Star label is awarded to products that use appliances and technology measures that significantly reduce energy consumption and save you money. A dehumidifier will be honored. d2c66b5586
