项目摘要

The goal of the "Efficient antiviral air filtration materials and systems to combat the COVID-19 pandemic" project is to develop novel air filtering systems that can absorb and neutralize infectious bioaerosols to prevent the transmission of epidemic respiratory diseases. A key objective is to design new filtration structure(s) to notably reduce the high pressure drop of the existing Personal Protective Equipment (PPE), e.g. N95 masks. This research combines the expertise of Dr. Bahrami's research team at Simon Fraser University (SFU) with BC-based industry partners 4M and Core to develop, characterize and evaluate the effectiveness of air filters that contain antiviral agents. The ultimate objective is to produce cost-effective respirators, facemasks, and HVAC filtration systems with enhanced performance, including: o Increased filtration efficiency, while maintaining minimal pressure drop to enable: - the use of PPE during work/daily activities for mask wearers; and - retrofitting of existing HVAC systems without compromising their capacity; o Enhanced protection through chemical deactivation of viruses that accumulate on the surfaces of filtering facepiece respirators and HVAC filters; o Reduction of the infection risk associated with doffing and disposal of Personal Protective Equipment (PPE), specifically virus-laden filter media.

“抗击新冠肺炎大流行的高效抗病毒空气过滤材料和系统”项目的目标是开发能够吸收和中和传染性生物气雾剂的新型空气过滤系统，以防止呼吸道流行病的传播。一个关键目标是设计新的过滤结构(S)，以显著降低现有个人防护装备(如N95口罩)的高压降。这项研究结合了巴赫拉米博士在西蒙·弗雷泽大学(SFU)的研究团队与不列颠哥伦比亚省的行业合作伙伴4M和Core的专业知识，以开发、表征和评估含有抗病毒药物的空气过滤器的有效性。最终目标是生产具有成本效益的口罩、口罩和具有更高性能的暖通空调过滤系统，包括： O提高过滤效率，同时保持最小的压降，以实现： -口罩佩戴者在工作/日常活动中使用个人防护装备；以及 -在不影响现有能力的情况下改造现有的暖通空调系统； O通过化学灭活积聚在表面的病毒来加强保护过滤面罩呼吸器和暖通空调过滤器； O减少与脱下和处置个人防护装备有关的感染风险 (PPE)，特别是含有病毒的过滤介质。
