Abstract
A refrigerator includes a main body having a storage room formed therein, a door that opens and closes the storage room, a filter module, and a cool air circulation fan that circulates cool air through the filter module. The filter module includes a metal photocatalyst filter and a UV LED module for radiating UV rays to the metal photocatalyst filter. The metal photocatalyst filter has photocatalysts made of one of ZnTiO, CuTiO, AgTiOor FeTiOcoated on a filter base. The filter module may allow the entire storage room to be uniformly subject to antibiosis and sterilization at a relatively low cost.
