• Danny Glover is shown coughing when he first enters the City Hunter's ship, and soon after he's shown having some difficulty breathing:

So, I think it's pretty clear that the Bio-Masks are intended to be all-around life-support gear with audio/visual enhancement, scanners, video recorders...pretty much whatever any given film's writer needs 'em to be, really.

The one inconsistency I'm surprised doesn't get mentioned more is the goof regarding the Jungle Hunter and City Hunter's heat vision, sans Bio-Mask. In Predator 1, JH's vision goes all red when he removes his mask, but in Predator 2 CH's vision remains exactly the same as when he had the mask on and doesn't . Hmmh.

The key word I used in my first post was "necessary." While I generally buy that humans and yautja normally exist in different atmosphere types there's no evidence that one is actually lethal to the opposite species. Predators (the movie) depicts a predator left in the open for hours without a mask on while the humans give no complaints regarding the air so in that scenario it's evident that the two can generally coexist for extended periods without the predator biomasks.
