Filtration Performance Evaluation of Various Respiratory Face Masks Against Sub-Micron Particles

Abstract 

Respiratory face masks are protective facepieces that are designed to filter inhaled air. They are easy-to-use

devices that can protect the wearer against various hazardous particles in the air. Respiratory face masks also

prevent the spread of viruses and bacteria-containing droplets that are released from the coughing or sneezing of

the infected people. During the COVID-19 pandemic, various types of face masks have circulated on the market.

Their ability to filter sub-micron particles, which are the sizes of harmful particulate matter and airborne viruses,

needs to be investigated. Their breathability, the easiness of breath through the mask, also needs to be considered.

In this study, wwe evaluated the performance of filters used for different types of face masks certified by different

standards including Korean (KF94, KF80, KF-AD), USA (N95), and Chinese (KN95) standards. We also tested the

filters of nanofiber masks and surgical masks for which there are no standards for filtration test. The N95 mask

filters showed the highest quality factor for capturing virus-sized particles. The other types of mask filters have

acceptable performance except for nanofiber mask filters whose performance is very low.
