To test the respirators fitness, we used quantitative fit test system to measure the fitness of the three models of new respirators worn by real person. The testing method is to use a differential mobility analyzer to select the particles of 40nm in diameter. N95 respirators are capable of filtering out almost all 40nm particles, therefore, the 40 nm particles measured within the respirator would be considered due to the leakage caused by poor fitness.

口罩密合度是使用定量密合度测试组合系统以真人分别配戴三款五年口罩A、B与C和同样型号新口罩来测试其密合度，测试方法主要是利用差异电移动度分析仪筛选粒径为40nm的微粒，而N95口罩的特性几乎可以完全过滤40 nm的微粒，所以口罩内量测到40nm粒径的微粒可被认定是泄漏造成。
