Abstract
The present application relates to a multifunctional filter medium and a method of manufacturing the same. The multifunctional filter medium of the present application is capable of significantly reducing fine dust, harmful microorganisms, and toxic gases and reducing a pressure decrease during filtration due to exclusion of high-density nanofiber, thereby minimizing energy required for filtration and exhibiting sufficient filtration performance as a single filter medium.
