The purpose of the present study was to evaluate the fit factors and total inward leakage (TIL) of commercially-available face masks in Korea. We selected a total of six face masks: surgical, KF AD, KF80, KF94, KF99 and N95. Six male subjects participated in a fit test, while ten subjects participated in TIL test. Among the subjects, only three subjects participated in both tests and the relationship between fit factor and TIL was analyzed using data from the three subjects. The results showed that 1) no relationship between filtration of mass and fit factor was found, 2) greater filtration level, smaller TIL; 3) smaller fit factor, greater TIL (r=0.498, p<0.05). However, the correlation was not that great, which was attributed to the differences in mask design (folded or flat type vs. cup type; ear loop vs. head band) and face types. In order to minimize leakage rate when wearing face masks, a cup type with seal and head bands is recommended rather that folded types with ear loops. It needs that the fit test should be a mandatory test for hospitals or occupational fields where workers should wear their own face masks to protect then from dusts or biological hazards. Also, the development of Korean face test panel should be precedent to conduct a fit test.
