Great question. Observe someone exhaling through a KN95 in cold weather and someone with no face covering in cold weather. What you'll quickly see is that the KN95 traps some of the vapor particles. In an infected person, those vapor particles contain the pathogen. Fewer particles mean lower odds of contracting and lower viral load if the disease is contracted. It's truly amazing how that simple and irrefutable truth escapes so many. These videos illustrate the simple concept.

There is no such thing as "vapor particles". There is vapor and there are aerosols. They are very different. We don't exhale aerosols. We sneeze aerosols, but we exhale vapor. Vapor may condense given the correct conditions.

BTW Vapor is always sterile.


Semantics aside, how would you argue that the videos are wrong?
