Most dehumidifiers use refrigerated coils to extract the water from the air. The dehumidifier makes these coils very cold, the air is passed over the coils and the excess moisture in the air, condenses on the coils, because they are cold.
With Ebac dehumidifiers the rate at which the water runs off the coils into the water container is higher because the coils are hydrophilic. This means the coils are coated with a special substance that makes water run off more rapidly. This allows water extraction and collection to be processed faster within the dehumidifier.
