Dehumidifiers are apparatuses used for removing water vapor from the air. A room dehumidifier is a small, portable unit that can be placed in the center of a damp room to dry the air. Most dehumidifiers operate by passing through a cooling device similar to the cooling coil of a refrigerator. Cooling makes the water vapor condense out of the damp air. The condensed vapor collects in a pan, which must be emptied periodically.



Each dehumidifier is different and each one has different features. The most common features of a dehumidifier are an automatic turn off switch that will turn the device off when the water pan is full. This is an excellent idea; therefore you don't have to worry about the pan overflowing while you are not around. You can turn on the dehumidifier and leave it and feel assured that it will turn off when full.

In area where the air cold and damp dehumidifiers might freeze up. This is a common occurrence. However today, more and more creators of dehumidifiers are working hard to have a defrost feature on the device. This feature turns the dehumidifier off when it freezes up and then turns it back on when the ice is melted. This occurs in places when the temperature and relative humidity are low.

If you are looking to take the dampness of a room that is always cold and damp then you might want to look into getting a dehumidifier/heater combination device. This system will remove the dampness from the room while heating the room at the same time. These devices are sometimes more expensive then the normal dehumidifier but it will be worth it if it makes the room warmer and less damp.
