If there were such a thing, people who suspect they have sleep apnea would
have it made against the medical establishment then, I think?

I was thinking it should be easy to find some $40 fan/pump that would
deliver low-pressure air from a clean air location, via hose, to a
mask.

Not so. They all seem to want many hundreds of dollars.

What gives? I'm not asking suck air through a garden hose, but this
doesn't seem like a big feat of engineering. I don't even need HEPA
filters.
