Mask test and facial measurements were conducted by the same researcher using the HSE standardised face fit testing protocol. The participants represented 22 different industries, the majority (90%) of whom were male. Fit factor (FF), representing the ratio of the exposure concentration outside to...
We note large differences in face mask usage across countries in our data, with average agreement per country ranging from 1.43 to 4.37. Colombian and Indian students indicated the highest agreement with face mask use, whereas agreement was lowest among Dutch and Swedish students. French students s...
Fit testing confirms the fit of a full-face mask that forms a tight seal on the user’s face before it is used in the workplace. This ensures that users are receiving the expected level of protection by minimizing contaminant leakage into the facepiece. When a full-face mask does not ...

Nevertheless, by testing the role of this explanatory mechanism, we provide a more complete depiction of differences in face mask wearing between the genders. From these efforts, the current investigation poses many benefits for research and practice. First, we identify a potential population (i.e...
facemask use among the general population. This meta-analysis aimed to explore (1) the efficacy of facemask use on preventing respiratory infections, and (2) the perceptions, intentions, and practice about facemask use among the general population worldwide. We searched PubMed, MEDLINE, Web of...
