[QUOTE="Texas Speed Bump, post: 2368616, member: 115057"] I've worked as a Safety Officer for a large hospital network for over 30 years and in that time have fit-tested well over 1,000 people for N-95s and other types of tight-fitting respirators. A "100-series mask" (respirator) is actually even more efficient than an N-95. The "95" part of the name refers to the percent of particles 0.1 microns or bigger that it filters out. So an N-95 will filter out 95% of those small particles whereas a '100-series' respirator will filter out 100% of them. The difference between those two numbers however isn't significant in my book. There's also the fit of the respirator to consider. If you're just wearing one for dust or COVID protection in a non-hospital setting, fit testing the respirator isn't that big a deal but if you wear a respirator to avoid a serious allergic reaction, than fit is important. Most N-95/100 respirators come in different sizes and it would be difficult for the average person to conduct a proper fit test on themselves. Our hospitals recently switched to the 3M 1870+ which only comes in one size and we've found fits about 95% of the people we've tried it on. Another advantage of this respirator is that it doesn't muffle your voice when you speak through it. [/QUOTE]
