ResMed CPAP machine, airsense 10. Came from Dad's estate, has been in storage for more than 5 years. Totally cleaned and sanitized and tested! I use this machine for 3 nights with my tank, and tube and face mask, works fine. Auto shut off does not always work, might be a setting? Notification pops up saying motor life exceeded. But seems to work fine. I will warranty this for 7 days if purchased. Comes with SD card, instruction manuals, two heated hoses, extra tank, 20 air filters, two air fit 10 masks size large brand new, two airfit Mass size medium brand new. Price firm, cash, venmo, Ezell
