Une série d’expériences a été réalisée afin d’étudier l’efficacité de MASI à éliminer les espaces entre le masque et l’utilisateur et à fournir une efficacité de filtration similaire à celle des masques N95.
Mask wearing has become critical for preventing the aerosolization and inhalation of virus-laden particles during the ongoing COVID-19 global pandemic. However, facial masks with effective filtration are either not readily accessible (e.g., N95) or have reduced filtration efficiency due to air gaps between the mask and wearer (e.g., cloth masks). We have developed a novel combination of a mask and shield named Mask And Shield Integrated (MASI) that provides nearly the same levels of protection as an N95 mask by addressing these issues. Magnetic latches reduce gaps between the mask and wearer, while a novel fin structure on the shield provides protection against floating particles. A series of experiments was performed to study MASI’s efficacy in both eliminating mask gaps and also providing N95-like filtration efficiency. MASI was found to solve both problems, thus providing a low-cost mask solution that can be applied to a broad range of environments to prevent inhalation of small air-borne particles.
