摘要
针对口罩阻挡新冠病毒的检测方法问题,在讨论病毒特征、口罩作用基础上,对目前国内普遍采用的细菌过滤效率(BFE)和非油性颗粒过滤效率(PFE)检测方法进行了对比研究。结果表明,颗粒过滤效率与细菌过滤效率没有相关性,用颗粒过滤效率替代细菌过滤效率的风险较大。
For the inspection method of anti-Covid-19 function of mask,based on the virus characteristics and mask functions,the bacterial filtration efficiency(BFE)and non-oily particle filtration efficiency(PFE)inspection methods commonly used in China were compared.The results showed that there was no correlation between particle filtration efficiency and bacterial filtration efficiency,and there was a greater risk in using particle filtration efficiency to replace bacterial filtration efficiency.
