KN95 Respirator Mask
For use in hospitals and nursing homes.
KN95 filtering face piece respirators (FFR), which are sometimes called disposable respirators, are subject to various regulatory standards around the world. These standards specify certain required physical properties and performance characteristics in order for respirators to claim compliance with the particular standard. During pandemic or emergency situations, health authorities often reference these standards when making respirator recommendations, stating, for example, that certain populations should use an N95, FFP2, KN95 or equivalent respirator. Please see below the 3M Technical Bulletin for more information and comparison.
