This is the next generation Auto CPAP machine by Devilbiss. This unit is backed by a 5 Year warranty, the most among any cpap machine. The IntelliPAP AutoAdjust System has the smallest surface of all leading CPAP devices with heated humidification system attached and comes equipped with all the necessities for use during travel or at home. The eight-foot power cord length provides greater positioning flexibility – no bulky power brick on cord. Now with the new SmartFlex built in, the AutoAdjust provides exhalation relief along with smooth, transitioning pressure when needed. It is one of the quietest machines on the market (26dba) and with SmartCode, the IntelliPAP can generate therapy reports through the Internet.
