Based on personal experience I have to go with Monona on this one. Of course, I've never worn one of these particular enclosed face shields. But I have worn
PAPRs with a neck shroud. If the pump fails, or you experiment with turning it off, after a few breaths breathing becomes pretty uncomfortable due to exhaled CO2. That's because of all the dead space in the helmet. With a cloth face mask, there's almost none.

The fabric around the edges is cloth, so I really don't think it would be any harder than breathing through a cloth face covering. I think it's an interesting
hybrid between face coverings and face shields that might be used to address a variety of situations that have been discussed here recently.

Gee that would be perfect if we didn't need oxygen. Each time you exhale in that thing your breath fills the space and some leaks out round the edges. When you
inhale, you breathe in mostly what you just exhaled plus a little that leaks in from the sides. The CO2 level is going to rise and I give that patient about 4 minutes before there is some heavy breathing and a complaint made familiar by activists.
Note the video says it is just for moving patients from one place to another. Wouldn't work in a NYC hospital where you typically are grown over by moss while
you wait in the hall on gurney.

This was posted on the ABSA listserv, and I thought there might be some interest in this community as well given recent discussions.
All the best,
Kristi
