If you combined N95 with additional PPE and used it all properly and only for short periods and removed the N95/PPE properly with decontamination procedures, it would reduce transmission. Know anyone that did that? Like I said, uncomfortable topics for those who thought their bit of blue paper was a magic charm.
It wouldn't reduce transmission even if you did all that. You could maybe reduce transmission with a full on hermetically sealed hazmat suit and scuba apparatus, but even then you're still going to be risking catching a minor cold.
Based on various studies of nurses in hospital settings, who presumably are following these procedures using N95 masks, there was no demonstrated benefit.
Arguable that they provide any benefit for any humans anywhere, since evidence for efficacy seems to be related to tests on mannequins rather than actual living, breathing, moving human beings.
One of these things is not like the other, but delving into that would raise uncomfortable questions for Branch Covidians.
They are all the same in that none of them actually work to block virus transmission.

i hope they have someone just standing there checking if it's n95
