Chemistry of covid-masks and graphene oxide: Any chemistry majors here?

There's a recent article on orwell.com that points to the masks as producing acidity that results in reducing the graphene oxide. Can anyone with chemistry background review this? Thanks.

When you wear a mask, your blood becomes more acidic and it activates the graphene in your blood more easily. Then it's called reduced graphene oxide (rGO). Acidity results from wearing a mask because you're breathing your own carbonic acid [Pianoman: ? Does he mean carbon dioxide?] which activates and converts the graphene oxide into reduced graphene oxide faster.
