Filtering facepiece 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 “KN95, FFP2, or equivalent” respirator.
