The Z1 cpap machine only makes 26 dBA of sound during operation. By cpap industry standards that is considered to be exceptionally quiet. In fact, the Z1™ is one of the quietest travel machines on the market.
The Z1™ is the lightest cpap machine available anywhere. At only 10 ounces it is a great everyday machine that is also ideal for travel.
The Z1 cpap system has an optional* integrated battery system that we call the PowerShell™. It delivers a full night of cord-free power on a fully-charged battery.
