The KN95 face mask is a Chinese standard mask. Derived from China National Standard GB 2626-2006 “Respiratory protective equipment self-priming filter anti-particulate respirator”.This standard is a compulsory national standard in China, proposed by the State Administration of Work Safety and under the jurisdiction of the National Technical Committee for Standardization of Personal Protective Equipment (SAC / TC 112).KN95 face mask In terms of scope of application, this standard is applicable to ordinary self-priming, filter-type respiratory protective equipment that protects against various types of particulate matter, such as masks, and other special environments CE FDA kn95 face mask (such as oxygen-deficient environments, underwater operations, etc.) are not applicable.
