Comparison of performance standards for mask filtration

As we all know, aerosol transmission is an important transmission route of the novel coronavirus. Therefore, when choosing a mask, people should pay attention not only to the filtration efficiency of BFE, but also to the filtration performance of PFE, which directly determines the protective performance of the whole mask.TezTextile Testing Instruments, Testing Equipment Manufacturer
