The fit of a respirator to the Face of an individual can be determined by a qualitative fit test((QLFT) or a quantitative fit test (QNFT). A quantitative fit test, was performed to evaluate leak values with Mask Fitting Tester. Two brands of half face respirators(M,S) were tested on 110 wearers on time. This study was investigated how the fit factors resulting from a quantiative fit test (QNFT) depend on the movements in the six test exersize regimes. Fit factor were low when face lengthes were higher or lower than average values. In this research we studies the koean's face length and compared the result with one of the American and the Japanese after wearing the Half-Mask Respirators, some changes in their leak were found and the results were as follows. 1. Although most testee were young, the Korean's face length were similar to the American while the male face length were similar to the Japanese. 2. For men, thier face length has been longer about by 1㎝ but mouth's length shorter about by 0.3㎝ than 10 years ago. 3. If the face length were not normality (such as higher or lower) leak degree was too high to be appropriate for the Respirator. 4. Both M and S company their respirators showed that the male leak degree was two times lower than female. Therefore, the resporators in the current market were believed to forcus it's target for male consumers. 5. The result of QLFT in a male showed that pass% of M was 20% higher than S. 6. In the result of QLFT, pass% of S was 25% highr than M in a female 7. These results(5&6) showed that S were more suitable in a female and M were more suitable in a male
