I have an AirSense11 CPAP machine with only 116.6 hours of use on it. The machine was used solely by my aunt for about 3 weeks. It is clean with several attachments in their original packaging. You may have to purchase a face mask (~$100-$150) and hose (~$16-$46) separately; I know I had these at one time but cannot seem to locate them at the moment. I will continue to look.
