Using an Auto CPAP machine and mask has been part of my lifestyle for the past 9 years. I would not be able to function without it now. When my wife started to complain of the noise from the machine, I knew it was time to upgrade. I couldn’t believe how simple it was to transition over the Dream Sleep Auto CPAP machine. An easy to follow functions screen, easy to clean humidifier, a sturdy travel case and quiet too!
