The fit and breathability of the mask are just as important as the filtration. Possibly more important.
If the fabric weave of the mask is too tight, with a really high thread count, or too many layers, it just acts as a diverter to funnel your breath out the sides and around your nose. Nothing gets filtered. |

Vietnam has had another outbreak. They had their first case the same week as us. We are kicking their ass 153,769 to 0. So much winning.
