PURPOSE: A fluid filtering apparatus is provided to improve credibility by determining accurately a filter washing period, and to offer automated fluid filtering apparatus without replacement, while reducing management costs of the apparatus. CONSTITUTION: A fluid filtering apparatus(100) includes the following: a main body(110) with a built-in pipe(111) and a discharge pipe(113), in which a hollow part is formed; a mesh metal filter(120) filtering fluid, and arranged to separate an inner hollow part and an outer hollow part; a foreign material removing device(130) discharging collected foreign materials, and arranged inside the hollow part; a control device(140) having a differential pressure detection sensor(141) measuring the fluid pressure. The foreign material removing device includes a driving motor(M), a washing pipe(131), a suction part, a foreign material discharge part(135), and a discharge valve(137).
