1. Medical protective masks: in accordance with China’s GB 19083-2010 mandatory standard, filtration efficiency ≥95% (tested with non-oily particles). Requires synthetic blood penetration testing (prevents body fluids from splashing) and microbiological criteria.
2. N95 mask: American NIOSH certification, non-oily particulate matter filtration efficiency ≥95%.
3. KN95 mask: meets China’s GB 2626 compulsory standard, non-oily particulate matter filtration efficiency ≥95%.
   The test methods for the filtration efficiency of the above three levels of masks are exactly the same! So the filtering efficiency levels are consistent.
   Therefore, the masks that you buy for NIOSH N95 and GB2626-2006 KN95 are the same. The key to wearing a mask is the close contact with the face, which is not leaking! Please take a closer look at the instructions before wearing.

   “The core standards of industrial masks and consumer product masks are the same. KN95 according to the GB2626 standard is sufficient. KN90 is actually sufficient. Only medical personnel have body fluid splashes and high environmental concentrations need to be very strict. But be aware that some The star mask is beautiful, but it does not care about the protection effect. “Said the 3M technician.
   Regarding the frequency of replacement, at present, there is no clear conclusion on the optimal wearing time of N95 masks by foreign countries including WHO, and there is no relevant regulation on the use time of masks in China. Some researchers have done relevant research on the protective efficiency and wearing time of N95 medical protective masks. The results show that the N95 masks have been maintained for more than 95% of the filtration efficiency for 2 days, and the respiratory resistance has not changed much; the filtration efficiency has been reduced to 94.7 for 3 days %.
