Also called surgical masks, these are loosefitting disposable masks. They're meant to protect the wearer from contact with droplets and sprays that may contain germs. A medical mask also filters out large particles in the air when the wearer breathes in. To make medical masks more form-fitting, knot the ear loops where they attach to the mask. Then...
A KN95 mask is a type of respirator that meets certain international standards. It offers more protection than a medical mask does because it filters out both large and small particles when the wearer inhales. But be cautious when buying a KN95. Some may not meet the quality standards, so consider researching the source carefully.
An N95 mask is a type of respirator that meets U.S. quality standards. An N95 offers the highest level of protection. It offers more protection than a medical mask does because it filters out both large and small particles when the wearer inhales. Nonsurgical N95s can be used by the general public.

A cloth mask is intended to trap respiratory droplets released when the wearer talks, coughs or sneezes. It also acts as a barrier to protect the wearer from breathing in droplets released by others. The most effective cloth masks are made of many layers of tightly woven fabric like cotton. A mask with layers will stop more droplets from getting th...
Our analysis, however, shows that the efficacy of face masks depends strongly on the level of infection probability and virus abundance: Masks reduce the infection probability by as much as their filter efficiency for respiratory particles in the virus-limited regime but much less in the virus-rich regime . Accordingly, experimental ...
Dec 19, 2020 · Face mask could significantly reduce the risk of SARS-CoV-2 infection (OR = 0.44, 95% CI: 0.21-0.93, I 2 = 52.0%). And no significant protective effect was shown in the N95 respirator group (OR = 0.17, 95% CI: 0.02-1.69, I 2 = 94.6%) in subgroup analysis.
