- Various antimicrobial technologies have been developed to inactivate bioaerosols in indoor environments. In this
study, air filter media were treated with a natural antibacterial agent of Sophora flavescens in order to inactivate the
bacteria collected on the air filter. Three treatment methods were applied to manufacture the test antibacterial air
filter media: electrospray, nebulization and dip-coating methods. In case of electrospray and nebulization
processes, the size distribution of aerosolized natural antibacterial agent was measured using a scanning mobility
particle sizer. Staphylococcus epidermidis bacteria were aerosolized to test inactivation of the filter media treated
with a natural antibacterial agent. The pressure drop and the antibacterial efficiency of the filter media increased
with increasing the mass loading of natural antibacterial agent in each treatment method. The antibacterial
efficiency per loaded antibacterial agent mass by the electrospray method was the highest and the filter treated by
the dip-coating method was the lowest among three treatment methods.
