Supplier Individually packaged KN95 protective Ordinary mask disposable export mask 3 layers
KN95 is a Chinese standard mask
Derived from China National Standard GB 2626-2006 "Respiratory protective equipment self-priming filter anti-particulate respirator"
1) Standard source
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).
(2) Technical content
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 (such as oxygen-deficient environments, underwater operations, etc.)
From the definition of particulate matter, this standard defines various forms of particulate matter, including dust, smoke, mist and microorganisms, but does not define the size of particulate matter.
From the point of view of the filter element level, it can be divided into KN type for filtering non-oily particulates and KP type for filtering oily and non-oily particulates, and with this as a mark, it is in accordance with the N, R / P specified in the interpretation guideline of CFR 42-84-1995 similar.

Notice:
It is worth noting that GB 2626-2006 "Respiratory protective equipment self-priming filter anti-particulate respirator" is about to be scrapped, replacing its new standard GB 2626-2019 "Respiratory protective self-priming filter anti-particulate respirator" The General Administration of Market Supervision and Administration issued the "People's Republic of China National Standards Announcement No. 17 of 2019" to the whole society on December 31, 2019, and will officially implement it on July 1, 2020. Be in charge.
At present, the text of the new standard has been published and is freely disclosed to the whole society as a mandatory standard. The new standard supplements seven terms such as “aerodynamic particle size” and modifies some technical requirements and detection methods, but does not modify the classification and marking and filtration efficiency listed in this article [1]
N95 is an American standard
The N95 mask is one of 9 types of particulate protective masks certified by NIOSH (National Institute for Occupational Safety and Health). N95 is not a specific product name, as long as it meets the N95 standard, and the product passed the NIOSH review can be called a N95 mask, which can filter particles with an aerodynamic diameter of 0.075µm ± 0.020µm to achieve more than 95%.
