Korea has a nice new mask. AirQueen. Reusable. Reasonably comfortable. N95-equivalent for filtration.
The seal isn't quite as good as a proper N95, but it beat surgical, and even surgical gets you almost all the way there.

The [CDC tested them](https://www.cdc.gov/niosh/npptl/respirators/testing/results/...) and their quality control leaves a lot to be desired.
If the variance for just 10 masks was so incredibly high, who knows how crappy the 99th percentile mask they produce is?
