PURPOSE: An oil filtering apparatus is provided to suppress environmental pollution by reducing the generation of waste oil. CONSTITUTION: An oil filtering apparatus includes a first line (100), a second line (200), a three-way valve (300), a third line (400), and a pollution measuring unit (600). The second line is positioned at one side of the first line. The three-way valve is installed in the first line and the other end of the second line. The first line includes a motor pump (P), and a first inlet (110) is formed at one end of the first line. Oil from the outside enters the first inlet. A second inlet (210) is formed at one end of the second line. Oil from the outside enters the inlets. Oil discharged through the three-way valve is transferred to the third line. The third line includes a filtering unit (500) and a discharging unit (410). The filtering unit filters the oil. The discharging unit discharges the filtered oil to the outside. The pollution measuring unit measures the pollution level of the oil transferred through the third line.
