Compressor Filter Core
The filter core of a dryer is very similar to a refrigerators condenser coil. It consists of metal fins that are cooled by the air that flows over them. The air then cools the hot gas inside the coils, which condenses into liquid water and drips into a pan below.
The dryer's filter is a mesh screen that filters out lint from the air and stops it from going into the dryer's motor. It is located at the front of the drum, where it catches most of the lint. A clean dryers filter can help extend appliance life and save on energy costs by reducing heat loss due to friction.
The filter core of a dryer needs to be cleaned once every six months for optimal performance and efficiency.
