The difference between mask N95 and KN95

 

 The N95 mask is one of the nine anti-particulate masks certified by NIOSH in the United States. "N" means non-oily particles; "95" means that the filtration efficiency reaches 95% under the testing conditions specified by the NIOSH standard. As long as the products meet the N95 standard and pass the NIOSH review, they can be called "N95 masks". This is the American standard. KN95 is the classification of anti-particulate masks in China's national standard GB2626-2006. The national standard GB2626-2006 ("Respiratory Protective Equipment Self-Priming Filtering Anti-particulate Respirators"), which was implemented on August 1, 2009, divides dust masks into three Grades: KN90, KN95, KN100.
