ResMed Airsense 10 AutoSet CPAP machine with humidifier. This is the standard (most prescribed) machine to which all others are compared. Retail price is $500-$600 depending on options. This has all options and accessories and works perfectly. Refurbished, with WiFi/BT smart interface if you choose to use it, downloadable data and options if you want (I didn’t use any of this tomfoolery, I just pushed the start button and went to sleep). (2) F20 AirFit mask sets each with a quick-release interface (size M & L) one is new, in package and one is used and professionally sterilized. One standard OEM 6 ft hose (new) and one (nicer/heavier duty) aftermarket 6 ft hose (sterilized). Optional humidifier tank included. Resmed OEM AC adapter/power-supply. Lifesaver! Lost 60 lbs and don't need it anymore!
