Filter material and method for fabricating the same

A filter material and a method for fabricating the same are provided. The filter material includes a supporting layer, at least one ion-exchange layer and at least one microfiltration layer. The supporting layer has a first surface and a second surface, wherein the supporting layer is composed of supporting micro- or nano-fibers. The ion-exchange layer including charged nano-fibers is disposed on at least one of the first and the second surfaces of the supporting layer. The microfiltration layer is disposed on at least one of the ion-exchange layer. The microfiltration layer includes microfiltration nano-fibers and fillers that fill pores between the microfiltration nano-fibers.
