Fabrication of an anti-viral air filter with SiO2-Ag nanoparticles and performance evaluation in a continuous airflow condition

- SiO2 particles surface coated with Ag particles were fabricated to coat an air filter.
- An anti-viral ability of the filter was evaluated against aerosolized virus particles.
- A mathematical approach of an anti-viral ability of the air filter was developed.
- A quality factor based on an anti-viral ability of the air filter was proposed.
