I researched what kind of VENTILATOR GM is making in Kokomo, Indiana
Turns out they are actually manufacturing the Ventec VOCSN device
Why not find the best device on the market and make more of THEM!
And if you want to add a function to a ventilator like internal UVA light
Then why not choose a device that is already designed to be multi-functional?
Look at the internals. Remind you of Tesla or Dyson engineering innovation?

As distributed by Ventec
Of course there is no telling whether or not GM has made their own mods.
