Characteristics of commercial antimicrobial filter media for bioaerosol removal were estimated. A chitoasn/ medium filter, a catechin/HEPA filter, a silver/HEPA filter, a copper/pre filter, a electret cabin filter and a non-electret cabin filter were used for estimation. Filtration efficiency and antimicrobial efficiency was tested using Escherichia coli and Staphylococcus epidermidis. The electret cabin filter and the chitosan/medium filter showed the highest filtration and antimicrobial efficiency, respectively.
