TL;DR: It is discovered that fungal fragments are aerosolized simultaneously with spores from contaminated agar and ceiling tile surfaces and cannot be predicted on the basis of the number of spores.

TL;DR: The N95 filtering face piece respirators may not provide the expected protection level against small virions, and some surgical masks may let a significant fraction of airborne viruses penetrate through their filters, providing very low protection against aerosolized infectious agents.

TL;DR: Because most of the penetrated particles entered through the faceseal, the priority in respirator/mask development should be shifted from improving the efficiency of the filter medium to establishing a better fit that would eliminate or minimize faceseal leakage.

TL;DR: Through laboratory tests with NaCl certification aerosols and measurements with particle-size spectrometers, N95 respirators were found to have higher filtration efficiencies than DM and DFM respirators and noncertified surgical masks.

TL;DR: In this article, a new principle for collecting airborne particles, including microorganisms, has been introduced by injecting the particles into a swirling airflow from where they are removed onto a collection surface, such as a dry surface, a surface coated with an adhesive substance or a surface wetted by a liquid swirled onto the collection surface from a reservoir below.
