I am selling my well-maintained AirCurve 10. This is a top-end CPAP model from ResMed. Pricing to sell at $500. Comes with all usual accessories (carrying case, tubing, etc).
AirCurve 10 bilevel machines include two pressure level settings: a higher pressure when you inhale, and a lower pressure that makes it easier to exhale. It is compact, rugged and lightweight, with intelligent design enhancements, and user friendly controls.
