Filtering face-piece respirators (FFR), which are also called disposable respirators, are subject to various regulatory standards around the world (see examples below). Certain required physical properties and performance characteristics are specified in order for respirators to claim compliance with the particular standard. N95/KN95/FFP2 respirators are commonly recommended by health authorities during pandemic or emergency situations. They are not exactly the same, but respirators certified as meeting these standards can be expected to function very similar to on another.
• N95 (United States NIOSH-42CFR84) • KN95 (China GB2626-2006)
• FFP2 (Europe EN 149-2001)
3M released a Technical Bulletin on January 2020 regarding Comparison of FFP2, KN95, and N95 and Other Filtering Face-piece Respirator Classes. Based on this comparison, it is reasonable to consider China KN95, as “equivalent” to US NIOSH N95 and European FFP2 respirators, for filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bio-aerosols (e.g. viruses). 2.
