Due to the coronavirus pandemic (COVID-19), hospitals in Canada and around the world have faced a shortage of disposable N95 masks. Besides the immediate desperate need of facemasks, hospitals will encounter waste management challenges of N95 masks in the long term. This project aims at addressing these two challenges by designing, manufacturing and certifying reusable N95 masks to combat COVID-19. A mask solution that can be reused will be proposed and the optimum filtration method will be selected by the help of the partner organization, APC Filtration Inc. Reusable masks will be manufactured and tested to acquire National Institute for Occupational Safety and Health (NIOSH) certification. In addition, materials performance tests as per Health Canada requirements will be completed. A sterilization process for the reusable mask structure will be proposed and its impact on the structure will be investigated. The certified design per NIOSH will be used for designing and manufacturing a cast for high volume injection molding of 1000-5000 parts/day for a total of 500,000 parts. The work with our highly qualified team from Ryerson and APC Filtration Inc. will result in an innovative product that will help in the fight against the COVID-19 pandemic in Canada and worldwide.

由于冠状病毒大流行（COVID-19），加拿大和世界各地的医院都面临着一次性N95口罩短缺的问题。除了急需口罩外，医院还将长期面临N95口罩的废物管理挑战。该项目旨在通过设计、制造和认证可重复使用的N95口罩来应对这两个挑战。在合作伙伴APC filtration Inc.的帮助下，将提出一种可重复使用的掩膜解决方案，并选择最佳过滤方法。可重复使用的口罩将被生产和测试，以获得国家职业安全与健康研究所（NIOSH）的认证。此外，将按照加拿大卫生部的要求完成材料性能测试。提出了一种可重复使用的口罩结构的灭菌工艺，并研究了其对结构的影响。符合NIOSH的认证设计将用于设计和制造每天1000-5000个零件的大批量注塑铸件，总共500,000个零件。与我们来自瑞尔森和APC过滤公司的高素质团队合作，将产生一种创新产品，有助于在加拿大和全球范围内抗击COVID-19大流行。
