I believe the Airing thing is expected to use these things:

I was also skeptical of the Airing claim, although after reading about the Murata piezo blower things, they're amazing, whether Airing is able to make a CPAP out of them or not.

Frankly, as an old, fat, CPAP using guy, I'd rather eat mouldy cheese than use a nasal pillow CPAP device. Plus, the Airing thing would have to be strapped to my face anyway; at my Rx pressure it'd blow out of my nose within an hour. The hose on my traditional BiPap turbine machine doesn't bother me at all.

I'd be delighted to have a smaller BiPap machine made out of these Murata things, if it meant a less bulky power supply and a smaller base unit.
