1-1 of 1 Answer

• The Water Filter for the ENERGY STAR® Qualified LG 21.8 Cu. Ft. French Door Refrigerator - Stainless Steel, Model # LFDS22520S is the carbon filter! The most common substance used for refrigerator water filter is activated carbon. LG water filters are made from Korean premium carbon block, along with Japanese coconut activated carbon. There is no other filter in the refrigerator...^IFV
