A Particle is a Particle
For decades, respirator researchers have been asked whether filters need to be tested with aerosols similar to those encountered in the environment. Common sense suggests that viruses or bacteria are collected differently from engineered nanoparticles, silica dusts, oil mists or other types of workplace aerosols. But that is not necessarily the case. (2016)

Do We Need to Challenge Respirator Filters With Biological Aerosols? (2014)
The purpose of this NIOSH Science Blog is to explain what is currently known about an important aspect of respirator filtration. For decades, respirator researchers have been asked whether filters need to be tested with aerosols similar to those encountered in the environment. Common sense suggests that viruses or bacteria are collected differently from engineered nanoparticles, silica dusts, oil mists or other types of workplace aerosols.
