So I will take a moment to explain something. When someone wears an N97 mask. They block up to 97 percent of the vapour carrying the viral load. Leading to 3 percent airborne. This 3 percent has a life span. And thinly spread has a minimal chance or being contracted. When so are ina room with the virus and your mask stops 60 percent of vapour. You still have a 100 percent chance of contraction. As the virus successfully entered the system. You don't need 100 percent of it.

This is why it is important everyone wears masks the viral load if both people are wearing drops to 40 percent of 3 percent, if contact is made. Do not enter environments with people COVID positive expecting a standard N97 to protect you
