本集团已开发新型布质口罩以减缓COVID-19的传播，并测试粒子（0. 1微米大小）过滤效率、细菌过滤效率、透气性、泄漏、心率和血氧水平，然后与现有的N95口罩和外科口罩进行比较。结果发现，这种新型口罩的过滤效率优于外科口罩，与N95口罩非常接近。透气性也得到了改善，并在指定的范围内为屏障面覆盖物的水平。利用流动可视化技术研究面罩的泄漏，发现与外科口罩相比，其泄漏显著降低。在10分钟的步行过程中佩戴口罩进行心率和血氧水平测试，发现佩戴口罩不会对心率或血氧水平产生不利影响，也不会给佩戴者增加任何其他压力。我们相信，此新型口罩将减少COVID-19的传播，并为公众提供一种环保及经济的N95口罩替代品。这项研究中开发的口罩可以清洗，重复使用，因此可以佩戴更长时间。
Novel cloth face masks to mitigate the spread of COVID-19 have been developed and tested for particle (0.1 μm in size) filtration efficiency, bacterial filtration efficiency, breathability, leakage, heart rate, and blood oxygen level, and then compared with the available N95 masks and surgical masks. It was found that this novel mask had better filtration efficiency than that of surgical masks and was very close to that of N95 masks. The breathability was also improved and was in the range of the designated levels for barrier face coverings. The flow visualization technique was utilized to study the leakage of the mask and it was found to have significantly lower leakage as compared to surgical masks. Heart rate and blood oxygen level tests were performed by wearing the mask during 10-minute walking sessions and it was found that wearing the mask did not adversely affect heart rate or blood oxygen levels or add any other strain on the wearer. It is believed that this novel face mask would reduce the spread of COVID-19 as well as provide an environmentally and economically conscious alternative to the N95 respirators for the public. The mask developed in this study can be washed, reused, and therefore worn for longer periods of time.
