Surgical masks and respirator masks serve different purposes, so they are designed differently. Andrew Stanley Pekosz, a professor of molecular microbiology and immunology at Johns Hopkins University Bloomberg School of Public Health, says surgical masks are basically small pieces of cloth people use to keep the germs from their coughs and sneezes to themselves, or to prevent picking up other people's viruses and baktiria. "Em i wanpela jeneral fisikel blok tru bilong stopim ol bikpela mak bilong wara long kisim maus bilong yu," Pekosz i tok .Lewa.
Respirator masks, Pekosz says, are more sturdily designed than surgical masks, and they contain a respirator that prevents much smaller particles from passing through to a person's respiratory system. Two of the most common respirator masks are N-95 masks and N-99 masks, which, when used correctly, prevent 95 percent and 99 percent, respectively, of airborne particles long go insait long maus bilong man o nus.
