The main function of the KN95 mask is to protect against non-oily particles, and its filtration performance is directly related to the protective effect of the mask. According to the national standard, the KN95 mask is 0The filtration efficiency of 3 m particulate matter should reach more than 95%. Therefore, testing filtration performance can ensure that masks meet this criterion and thus effectively block aerosols with novel coronavirus particles. Therefore, it is very important to test the filtration performance of KN95 masks.
KN95 mask particulate matter filtration efficiency tester is a testing equipment commonly used to test the filtration performance of KN95 masks.
KN95 mask particulate matter filtration efficiency tester is used to test the filtration performance, protective filtration efficiency and filtration effect of KN95 masks.
