So maybe droplet containing virus gets trapped in mask

A droplet will be mostly water. We are talking about very small particles (virions). COVID virions are 50–200 nanometres in diameter, averaging 125.

Even the N-95 won't filter these things effectively.

LOL! If they don't trap viruses they can't be a reservior for them.

Oh, and a virion is NOT a "virus particle."
