After the appearance of sand and dust weather, National Health Commission promptly issued health protection tips for sand and dust weather, pointing out that N95 and above protective masks should be worn in sand and dust weather. N95 and above protective masks commonly used in daily life, including N95 masks and KN95 masks, belong to particulate matter protective masks.
Among them, N95 respirator, also known as N95 respirator, is made according to the standards set by the American Institute of Safety and Health, and the efficiency of filtering particles reaches over 95%. KN95 mask implements the mandatory standard of China GB2626-2006, and the filtration efficiency of non-oily particles is more than 95%. In other words, the protective force of KN95 mask and N95 mask is the same, and the level, technical requirements and testing methods are the same, but the former is China standard and the latter is American standard.
