The Importance of Checking for NIOSH Certification
NIOSH certification only applies to a respirator as it was originally tested. Even the slightest modification to a certified respirator may affect its fit, form or function, thereby voiding its NIOSH certification. This N95 respirator was tested in its original form and received NIOSH certification.
Respirator Precertification (NIOSH) Tests Nelson Labs
The test is performed in compliance with 42 CFR Part 84 and NIOSH Procedure No. RCT APR STP 0051 0056, 2005 and is necessary for prequalification for NIOSH certification of respirators. Nelson Labs has extensive experience testing filters and other filtration devices.

Comparison of nanoparticle filtration performance of NIOSH
Initial penetration levels of polydisperse NaCl aerosols [mass median diameter (MMD) of 238 nm] were measured using a method similar to the NIOSH respirator certification test method. Monodisperse aerosol penetrations were measured using silver particles for
Respiratory Protection for Workers Handling Engineered
Dec 07, 2011 For example, the current NIOSH certification test for filtration performance (to determine whether a respirator is at least 95, 99, or 99.97% efficient) uses a broad range of particles, including a significant number of nanoparticles, but only measures particles larger than ~100 nm in size penetrating through the filter.

KN95 vs. N95 Masks It Is Time to Use Common Sense
Mar 24, 2020 Non fit tested N95 respirators were significantly more protective than medical masks against clinical respiratory illness. Rates of infection in the medical mask group were double that in the N95 group. Unlike N95 masks, the KN95 and FFP2 masks are manufactured by hundreds of companies. They vary in shape, size and fit.
