Comparison of FFP2, KN95, and N95 Facepiece

Views:109     Author:Site Editor     Publish Time: 2020-04-04      Origin:Site

According to EU standards (EN 149: 2001), FFP2 masks (medium filtration efficiency masks, filtering 94% particles) are similar to N95 masks in non-oily particle filtration, and higher standard FFP3 (high efficiency filter masks) can filter 99% particles , With a higher level of protection. The EU and NIOSH standards are different, and oily (paraffin oil mist) and non-oily (sodium chloride) particles need to be filtered at the same time. The EU standards actually cover a wider range. Other common European standard suffixes: "R" is reusable, "NR" is not reusable, "D" passes the dolomite obstruction test (that is, the breathing resistance increases slowly after the mask absorbs dust).


Australia: P2 mask

In Australia, masks similar to N95 are called P2 masks.


Japan: DS2 masks and RS2 masks

The Ministry of Health, Labor and Welfare ’s “Specifications for Dust Masks” (March 30, 1973, Ministry of Labor Notice No. 19) stipulates that disposable masks that can filter more than 95% of sodium chloride particles during testing are DS2 masks and reusable masks RS2 mask [28]; the dustproof effect of the two is similar to that of N95 mask.


China: KN95 mask

The KN95 mask is the mask standard defined in the National Standard GB2626-2006 of the People's Republic of China. KN represents the protection against non-oily particulate matter. Refer to the N95 mask. 95 represents the filtration efficiency of 95.0% or more when tested with sodium chloride particles. The dustproof effect of KN95 is equal to that of N95, so KN95 masks and N95 masks can be replaced with each other.
