The answer to 'how does dehumidifier work' is that a dehumidifier is a device that removes excess moisture from the air in a room or building. It works by drawing in warm, humid air and passing it over a cold coil. As the air passes over the cold coil, the moisture in the air condenses into water droplets, which are then collected in a tank or drained out of the unit. The dry air is then circulated back into the room, helping to reduce the overall humidity level.
Dehumidifiers are commonly used in homes, basements, and other damp areas to help control moisture levels and prevent issues like mold, mildew, and musty odors. They can also help improve indoor air quality and make the air feel more comfortable.
