Wearing a mask has been strongly advised as protection against COVID-19. According to a recent study by the Centers for Disease Control and Prevention (CDC), wearing masks can reduce the risk of coronavirus by more than 70%. So the question that pops up is if one mask can reduce the risk to such an extent, then how is effective will wearing two masks be? Here’s what experts have to say.
Wearing a double mask might be efficient, according to Firas Zabaneh, MT (ASCP), CIC, CIE, director of system infection prevention and control for Houston Methodist Hospital in Houston, Texas. It comes from the point of view of filtration. Wearing two masks increases the layer of filtration thereby allowing lesser particles to enter. Thus, it increases the filtration capability of the mask.
