Complete nonsense. It is nearly impossible to make a seal that is completely impermeable to all gasses, but an aerosol carrying a virus is a thousand times larger than something like butylthiol, the odourant added to natural gas.
the mask commisars weren't saying the masks worked for blocking just aerosol virus but the free floating virus itself, which was my point, if you can smell things through the mask you can breath in the free floating virus because the filter size and the incomplete seals.
