Why Is Your Dehumidifier Frosting Up? Easy Explanations & Fixes
The Simple Science of How a Dehumidifier Works
Think of your dehumidifier as a mini refrigerator. It pulls in warm, moist air from your room and passes it over very cold coils (called the evaporator). The moisture in the air condenses into water droplets on these cold coils—just like water droplets form on a cold drink can. The water then drips into the tank, and dry, slightly warmer air is blown back into the room.
