By comparing the corresponding testing standards of kn95 and n95 masks, it can be found that the requirements for key indicators such as particle filtration efficiency, breathing resistance, and exhalation valve air tightness are consistent between kn95 masks and n95 masks.
However, the pretreatment conditions that the kn95 mask filter membrane needs to undergo during the test are more complex and demanding, and there are specific numerical requirements for headband tension, connections and connecting parts, dead space, field of view and other indicators, while n95 does not.
