Data underlying the research on evaluation of masks and mask material suitability for bioaerosol capture

This research provides a quantitative evaluation of various non-medical facemasks, assesses their potential for the reduction of transmission of bioaerosols such as the SARS-CoV-2 virus, and compares them to medical masks. Using a testing line with a NaCl challenge aerosol, four types of commercial reusable cloth masks, two types of disposable non-medical masks, three types of medical masks and seven types of commonly available materials were tested individually and in combinations. The testing line and procedure were adapted from the ASTM F2299 testing method used for testing medical masks. <br> The data is organized by mask type and face velocity the mask was tested at.

本研究对多款非医用口罩开展定量评估，测算其在阻断包括新冠病毒（SARS-CoV-2）在内的生物气溶胶传播方面的潜力，并与医用口罩进行对比。本研究采用搭载氯化钠（NaCl）挑战气溶胶的测试台，对4款商用可复用布制口罩、2款一次性非医用口罩、3款医用口罩以及7种市面常见材料分别开展单独测试与组合测试；本次测试的测试装置与测试流程改编自用于医用口罩检测的ASTM F2299标准测试方法。<br>本次测试数据按照口罩类型与测试时的面风速进行整理分类。
