There is no consensus by scientists that masks do anything to stop the spread of Covid

An N95 FFR removes particles from the air that are breathed through it. These respirators filter out at least 95% of
very small (0.3 nm) particles. N95 FFRs are capable of filtering out all types of particles, including bacteria and viruses.
The diameter of SARS-CoV-2 virus has been found to range between
50 nm to 140 nm.
Now stop sounding retarded by saying "masks dont stop the spread of Covid"
