This is not a scientific argument (correlation is not causation), but it's an argument supported by numbers, not just words.
If we look at scientific studies, they also confirm the

One study on mice, I saw, showed that antiviral-coated masks increase the likelihood of developing immunity to infection BEFORE the infection, because fragments of dead viruses enter the lungs and trigger an immune reaction.
