I mean, if 2 masks are good…

The researchers found that wearing one mask — surgical or cloth — blocked around 40% of the particles coming toward the head that was breathing in. When a cloth mask was worn on top of a surgical mask, about 80% were blocked.
I’m sure a majority of the low-IQ heathens inhabiting the USSA would wear four or five if they were told to. It’s not like their brins benefit from oxygen.
