Made in Canada Reusable High Efficiency Respirators to Protect Against Spread of COVID-19

该合作伙伴关系的目标是生产可重复使用的高效消毒剂，以防止严重急性呼吸道综合征冠状病毒2（SARS-CoV-2）的气溶胶传播，该病毒导致2019冠状病毒病（COVID-19）。 拟议的研究项目将评估混合，天然合成纤维织物混纺的性能，用作可重复使用的过滤器中的过滤介质。 将测量两个关键性能参数：过滤效率和压降。 将研究过滤器性能作为干和湿负载以及重复清洁和消毒循环的函数。 通过这些测试产生的数据将指导合作伙伴组织与公共卫生当局合作，起草可重复使用的净化器的延长使用建议，包括清洁和消毒过滤介质的说明。 发展加拿大供应的高效率、可重复使用的制冷剂，将对缓解目前制冷剂供应短缺的情况产生潜在影响，从而为公众广泛使用这种制冷剂打开大门。

The goal of the partnership is to produce reusable, high efficiency respirators for protection against aerosol transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19). The proposed research project will evaluate the performance of hybrid, natural-synthetic fabric blends for use as filter media in reusable respirators. Two key performance parameters will be measured: filtration efficiency and pressure drop. Filter performance will be studied as a function of dry and wet loading, and over repeated cleaning and sanitization cycles. Data generated through these tests will guide the partner organization, working with public health authorities, in drafting extended use recommendations for reusable respirators, including instructions for cleaning and sanitizing filter media. Development of a Canadian supply of high efficiency, reusable respirators will have potential impact in relieving the current supply shortage of respirators, thereby opening the door for such respirators to become widely available to the general public.
