The fit of your face mask has a lot to do with how effective it is — the tighter the better for filtering your breath and keeping others safe from viral particles, including those of COVID-19. That ...

While it's still important to wear a face mask in many situations, that mask won't be fully effective if it doesn't fit properly. That's why a team at MIT has designed a device to assess how well a ...

Wearing a mask can help prevent the spread of viruses such as SARS-CoV-2, but a mask's effectiveness depends on how well it fits. Currently, there are no simple ways to measure the fit of a mask, but ...

In a recent article published in the journal Physics of Fluids, researchers explored the influence of perimeter leakage on the effectiveness of face masks. Study: Perimeter leakage of face masks and ...

Fig. 1. Given (a) the scanned face model of a subject, we develop an optimization-based approach to design (b&c) a PAP mask cushion that fits the face model. (d) The designed mask cushion is ...

A new sensor can measure biological and environmental signals, and evaluate how well a face mask fits by measuring physical contact between the mask and the wearer's face. Wearing a mask can help ...

In a new study, researchers used principal component analysis along with fluid dynamics simulation models to show the crucial importance of proper fit for all types of masks and how face shape ...
