Abstracts
Since airborne viruses have been known to aggravate indoor air quality, studies on development of anti-viral air
filter increase recently. In this study, a mass aerosol particle generator for coating a commercial air filter (over
300x300 mm2) was built, and evaluated by comparing a commercial particle generator. Then, via this device, a
commercial air filter was coated with anti-viral material (SiO2-Ag nanoparticles in this study), so fabrication of
commercial anti-viral air filter was performed and the pressure drop, filtration efficiency, and anti-viral ability of
the filter were evaluated against aerosolized bacteriophage MS2 in a continuous air flow condition. The result
showed that the particle generation of the new generator was more than about 8.5 times over which of the
commercial one. Consequently, SiO2-Ag particle coating on a filter does not have significant effects on the
filtration efficiency and pressure drop with different areas, and the average anti-viral efficiency of the SiO2-Ag
filter was about 92% when the coating areal density was 1.0¡¿1012 particles/m2.
