The invention relates to a micron fiber/nanofiber composite filter material and a preparation method thereof. The preparation method includes: in an electrostatic spinning process, an annular gradient solvent vapor quick removing device is adopted for one-step forming on a receiving substrate to obtain the micron fiber and nanofiber integrated three-dimensional structural composite filter material according to a double-region isolation spinning control technique. Efficiency of the micron fiber/nanofiber composite filter material in filtering of 0.02-10micron particles reaches 99.95% or above, and resistance pressure drop is smaller than 40Pa. The preparation method is simple in process, controllability in fiber diameter and pore diameter is achieved, the obtained composite filter material is of micron/nano scale in fiber diameter and pore diameter, a great filtration performance is achieved, and the composite filter material is widely applicable to air purifying products such as mask filter elements, air purifiers and air conditioners.
