A micron is 1/1000000 of a meter, 1/1000 of a milllimeter. An N-95 captures at least 95% of 0.3 micron particles, which is most of the floating "wet mass". Your article doesn't state that 0.1 micron droplets can transmit covid, only that it is plausible. So I (who also have a science degree, like FrommerStop) also viewed it as scare mongering.
I wear an elastic tube (one of my missus' hair stays) around my lower face over my N-95 to hold down the edges. It may also act as something of a pre-filter.
