PURPOSE:To hold a cooling tank to an aseptic state by using a filter system equipped with a plurality of filters. CONSTITUTION:In a filter system equipped with a filter 2 having a raw water inflow port 3 permitting raw water such as tap water to flow in, the cooling tank 7 connected to the filter 2 and cooling filtered water and the emitting port 10 connected to the cooling tank 7 and allowing cooled water to flow out to the outside, a bacteria removing filter 11 is provided between the cooling tank 7 and the emitting port 10 in order to prevent the invasion of bacteria from the emitting port 10. Bacteria do not invade from the emitting port by the presence of the bacteria removing filter and general bacteria can be removed from the filtered water of the cooling tank. Therefore, more safe filtered water can be obtained. |
