Abstract

An antimicrobial filter media, which includes a non-woven fabric; and an antimicrobial agent bound to the nonwoven fabric by a binder, the antimicrobial agent including silver sodium zirconium hydrogenphosphate and thiabendazole, and the silver sodium zirconium hydrogenphosphate and the thiabendazole are employed at a weight ratio of 1:1.5 to 1.5:1, to an air cleaner including the same, and to a process for preparing the same. The antimicrobial filter media includes silver sodium zirconium hydrogenphosphate and thiabendazole, as an antimicrobial agent, at a specific weight ratio. As a result, it is possible to effectively filter harmful microorganisms to supply purified air, to have excellent antibacterial, antiviral, and antifungal properties at the same time, and to further enhance the durability and lifespan characteristics by virtue of excellent filter damage prevention effect.
