Effects of UV-C Disinfection on N95 and KN95 Filtering Facepiece Respirator Reuse

Academic Article


  • Research suggests degradation of FFR materials at high UV doses is important. There appears to be a peak inactivation dose at approximately 1,500 mJ/cm 2 . The subsequent dose increases appear to have the reverse effect on inactivation values; these trends have shown true with both the N95 and KN95-Purism respirators.
