The structure of the filtering apparatus is simple, and also provides a method of backwashing filter system which can carry out back washing sufficiently. Thereby the raw water through the filter container (1) having a filter material layer (3,4) to the downstream. If the differential filtration pressure, elevated, and subjected to air back washing, back washing water with air and water backwash. When water with air backwash, air withdrawn valve 7, the water discharge valve 13, reverse wash supply station wash and air into the inlet valve 19 and to the air inlet valve 21 into the open filter tower (1) and deploy the filter material layer (3,4) and thereby separating the deposit adhering to the filter material. The air backwash water drainage flows out from the water discharge pipe 12.
