Abstract:
A fiber-based filter includes a filter-based porous body having a most frequent pore size from 0.1 μm to 2 μm in a pore size distribution, in which a ultra-fine fiber is continuously and randomly disposed, and a filtration layer having a nanonet layer having a most frequent pore size from 1 nm to 100 nm in the pore size distribution, in which an anisotropic nanomaterial is disposed. The fiber-based filter may have excellent filtration efficiency capable of removing even super-fine particles such as virus and heavy metal, and may show high permeation flow rate due to low loss of pressure during the filtration, and may be usefully used as an air and water-treatment filter.
