Additionally, it's a good idea to review lab testing documents that clearly illustrate how well a mask acts as a filter before you use it, says Anne Miller, executive director of Project N95 ...

About The Study: In this study of 824 N95s used by 412 emergency department health care workers practicing N95 reuse, fit failure occurred in 38.7% of masks after one shift. Trifold N95s had ...

Among 49,290 fit test results, 98.6% were passes, 0.7% were fails and 0.7% of tests were not completed.

In total, 100 participants successfully completed quantitative fit testing wearing a 3M1870þ N95 FFR.

A comparison study of popular N95 disposable respirators finds that the majority of those tested did not meet ASTM F3407-20 Respirator Fit Capability (RFC) Standard.

Without proper fit and seal against your face, an N95 may leak around the edges and offer far less protection than it claims. 75% of the N95s tested did not meet the fit capability standard. As a ...

"The fit test pass rate was very high for three-panel flat-fold type N95 respirator (96%), and health care workers rated their comfort and overall usability higher than those of semi-rigid cup ...

The North Carolina hospital was fined for failing to conduct N95 respirator fit tests, among other violations. HCA's Mission Hospital in Asheville, North Carolina has been cited and fined nearly ...

N95, KN95, and KF94 masks all have high filtration efficiency, meaning the materials they are made of, which usually consist of several layers, are extremely effective at filtering out tiny particles.
