Respirators :

Requirements of Respirators are more complicated than surgical masks. There are common parameters among the standards, filtering efficiency , differential pressure, etc. Other tests from different countries will have different parameters to measure the performance. Please find the following countries standards and the detailed information of performance test from our White Paper :
