N-95 masks are rated to capture 50 um (micrometer).
COVID-19 is 10.5 um. Water droplet to carry them just a tad bit above.
Hydrostatic testing to get that 50um in N-95 mask were based on 8.0 pH Latex hydrostatic droplets.
COVID-19 best infection spread rate is at 5.8-6.2 pH (opposite spectrum of Latex's pH).
So, more will pass thru that mask unhindered.
Nonetheless, the dispersal rate is lower only if the infected wears it. Tough to make a public policy on that to this day

- egberts1 4y agoBrownian motion gets impacted if ions repels (as well as attract) at molecular and atomic level. And like pH, it has ions depending on where across the pH spectrum. Now if they would construct a hydrostatic test using 5.8 to 6.2 pH aerosolizer, then the data becomes more robust.
- MengerSponge 4y agoThese numbers are suspect, and the conclusions are wrong. Filters don't work that way.
