Abstract Particle filtration field has been growing up together as airborne microorganism occurs problem as SARS or MERS. Therefore, various filters have been developed and invented for figuring out problems of airborne microorganism. Electrospinning and electrospraying method were used for fabricating and coating the filter. Silver nanowire coated nanofiber filter’s filtration efficiency and pressure drop were measured to evaluate performance test. Aerosolizing prepared bacteria which were bacillus cereus, staphylococcus aureus, and micrococcus luteus and virus which was MS2 bacteriophage carried out for performance test of silver nanowire coated nanofiber filter. Filtration efficiency of prepared nanofiber filters was measured upstream and downstream of the particle concentrations by aerosolizing prepared bacteria and virus. The concentration of bacteria and virus was measured by using an aerodynamic particle sizer (APS) and a scanning mobility particle sizer (SMPS). By using a differential pressure gauge, the pressure drop was measured between upstream and downstream. For anti-microorganism test, pristine nanofiber filter and silver nanowire coated filter were used for comparison. Colony counting method and plaque counting method were used to get anti-bacterial efficiency and anti-viral efficiency. These efficiencies show a similar tendency which anti-microorganism was increased with increase of silver nanowire’s coating time. Filtration performance test of silver nanowire coated electrospun nanofiber filter was evaluated by using APS and SMPS. Anti-bacterial and anti-viral ability of the filter were also evaluated. The silver nanowire coated electrospun nanofiber filter was evaluated to prove increase of the filtration efficiency and antimicrobial ability with increase of coating time of silver nanowire and steadiness of pressure drop.
