PURPOSE: A triple-layered metal filter is provided to maintain the original taste and smell of food and drinks regardless of filtration and to prevent the generation of foreign materials in filtering media. CONSTITUTION: A triple-layered metal filter is composed of first metal media(10), second metal media(15), and third metal media(20). The first metal media are woven with metal fibers having thin diameters. The second metal media are woven with metal fibers of mid-sized diameters. The third metal media are woven with metal fibers of thick diameters. The contact surfaces of the first metal media, the second metal media, and the third metal media are fused in a sintering furnace. The metal media are based on stainless steel. The first metal media implement a filtering process. The second metal media protect the first metal media. The third metal media reinforce the first and the second metal media in order to stand pressures applied to the filter.
