How affective is a kn95 mask against covid if the person wearing the mask is the carrier and theyre near a person not wearing a mask?
4 doctors weighed in across 2 answers
A KN95 mask is significantly more effective than a cloth or standard surgical mask, and if properly fitted and sealed, should minimize infectious aerosoluble droplet dissemination.

With the understanding that nothing is 100% in nature this type of mask is about the best we have. Other variables, such as time of exposure and actual distance are as important if not more important.
