Identification of masks begins with the letters.
The N-series is American standard.
The KN series is the Chinese standard.
The FFP series is a European standard.
The higher the number, the higher the protection level.
It’s easier to understand with a formula:
A number with a V at the end indicates a valve.
All the 95-headers are N95 series.
Central American and European standards for masks
n95 is manufactured in accordance with the American standard NOISH by 3M and Honeywell.
FFP2 is the European standard EN149.
KN95 is the Chinese standard GB2626-2006.
Different types of n95
Medical N95 masks require protection against high-pressure liquid spills, so they are held to a higher standard than regular N95; in the case of 3M, models 1860 and 9132 are the most commonly used medical protective masks.
There are also children’s versions of the 1860s.The average person or medical personnel who are not exposed to high-pressure liquid spills can choose a regular n95 mask that meets NOISH standards.
European standards for masks
European manufacturers of FFP2 standard masks include UVEX from Germany; FFP3 is a higher level (99) protective mask.
Chinese standard for masks
Chinese standard GB2626-2006 refers to the general KN95 mask standard.
The standard for medical KN95 masks is GB19083-2010.
(Similarly, regular KN95 masks may be used by ordinary people and medical personnel who are not exposed to high-pressure liquid spills.
Valves for masks
Regular masks with valves are more comfortable.
Medical masks are not allowed with valves.
Medical masks without valves must be chosen when the general population is infected or suspected to be infected.
The common standard is YY0469-2010, or YY0469-2011, which is printed on the individual outer packaging of each mouthpiece.
3M type of mask
1860 / 1870+ This model is used for medical work, moisture and dust protection, etc
8210 / 8511 This model is used for construction work, dust protection, etc
9210+ This model is used for industrial engineering, dust and corrosion protection, etc.
The N95 is a mask grade, so be sure to keep the 1860 / 1870+ model in mind when buying, or the one with the words anti virus, surgical, flu-fighter, otherwise it’s useless.
