PROBLEM TO BE SOLVED: To provide a filtration system usable over a long period of time by suppressing wear of a fine particle-like adsorbing material, and using fine particles having irregularities ofμm order and communicating pores of nm order. SOLUTION: The filtration system filtering foreign matter contained in a carrier includes fine particles having irregularities ofμm order and communicating pores of nm order, and a nonwoven fabric formed in a bag shape of inside-outside double structure having a filter function by laminating fibers inside while subjecting to the water repellent treatment to a surface region. The surfaces of the fine particles are held to an internal wall 2a subjected to the water repellent treatment of the nonwoven fabric 2, to retain the fine particles in block shape with the nonwoven fabric 2.
