You really don't seem to understand how little is required to make it work.
This snorkel mask and a hose to a nitrogen canister would be incredibly effective.
I'm not even joking. They made a 3D-printable adapter to the mask for attaching N99 filters. It's safe because it isolates incoming and outgoing air, which would make it work great.
And that's a hundred mask. The final design would obviously have more going on. For a couple hundred you can have one with an on-demand regulator operating just fine.
Or just use a SCBA (firefighting) mask hooked up to a nitrogen tank.
Are they doing that or just using something cobbled together from home depot leftovers? That is the concern.
The hundred dollar thing I just showed you IS a Home Depot solution.
Or they could grab a decommissioned mask from any fire department and hook it up to a nitrogen tank they got from Home Depot and it would work even better as a regulated system.
Or they can use a 40 dollar painting respirator hooked up to the nitrogen tank. That would also work great as a positive pressure system.
Or it wouldn't work at all. That's the whole idea. It's really hard to fuck it up, and if you do, then nothing happens at all.
Either it allows the nitrogen in and the CO2 out, or the nitrogen pressure pops the seal on a jammed mask and they can breathe just fine, or it doesn't show any air movement at all because the gas isn't on which is blindingly obvious within the first second and the mask is removed.
All it is is displacing regular 21/78 air with hypoxic air (doesn't even need to be pure N2 - lethal hypoxia is around 0.1PPO²) - neither of which contain enough CO2 to give the sensation of suffocation.
