Zusammenfassung:PROBLEM TO BE SOLVED: To provide a pre-main integrated air filter capable of replacing or cleaning a pre-filter and a main filter at the same time. SOLUTION: The pre-main integrated air filter has a frame 10 penetrating a front side and a back side and also having an opening over all the surface of these front side and back side, the pre-filter 12 structured by bending a sheet type filter material 18 alternately in a shape of pleat and arranged at an opening 10A of the front side of the frame 10, and the main filter 14 structured by bending a sheet type filter material 22, 24 alternately in the shape of pleat and arranged at an opening 10B of the back side of the frame 10, wherein the main filter 14 is formed as to be able to catch smaller particles than the pre-filter 12 and the pre-filter 12 has a larger surface area of the sheet type filter material than the main filter 14.
