A filter assembly according to the present invention provides sealing properties of a filter (60) by a filter fixing upper cap (70) and a filter fixing lower cap (40) regardless of strength of coupling when coupling a housing (30) with a coupling socket (20), because the filter (60) is not directly coupled with the housing (30), but independently coupled. Therefore, even the housing (30) is made with a fragile transparent polymer material compared with a metal, sealing properties of a coupling part of the filter (60) is obtained to prevent water leakage on the part, thereby maximizing filtering efficiency. |
