Can this surgical graded mask be used for COVID-19 virus? What are the minimum particles to be filtered and what is the efficency?
Per the CDC, COVID-19 is spread through respiratory droplets; masks, when properly worn, provide a barrier to prevent respiratory droplets from reaching others. We make no claims that these masks will completely eliminate the possibility of contracting COVID-19. The face masks have an average particulate filtration efficiency (PFE) of 98.5% and an average bacterial filtration efficiency (BFE) of 98%.
