Z1 Travel CPAP Machine & Auto CPAP Machine

The world’s smallest, lightest, most integrated CPAP machine.

In development for more than three years, we looked at every part and component in a CPAP machine and relentlessly attempted to improve upon it. From a smaller motor to a more compact circuit board, we whittled away every ounce of wasted space until we arrived at the Z1™; the smallest, lightest, most portable CPAP machine in the world.

Small enough to travel. Powerful enough to be used every day.

The Z1™ is an ideal travel machine. It literally fits in the palm of your hand so you will never have to leave your CPAP at home.


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.

Z-Breathe™. More natural breathing.

One of the greatest issues CPAP users complain about is the difficulty in exhaling against the pressure exerted by the CPAP machine. The Z1™ CPAP machine uses our proprietary Z-Breathe™ algorithm that learns from your breathing pattern and relieves machine pressure on exhalation.


Imagine being able to tuck a CPAP machine with very quiet operation that weighs less than a can of soda into a brief case or tote. Think how easily CPAP therapy can be made part of an active lifestyle when the tiny machine has an optional lightweight, integrated battery system to use on the go. The Z1 Travel CPAP Machine makes it a reality. This is a single pressure CPAP machine and delivers one set pressure all night long. It includes advanced features found on much larger machines meeting therapy needs while traveling or at home.

The Z1 Auto builds on the form-factor of the Z1™ CPAP to deliver the world’s smallest, lightest, most integrated auto-cpap machine. At only 10 ounces the Z1 Auto is the best machine we have released and when integrated with the PowerShell™, the Z1 Auto delivers an amazing night’s sleep on a single battery charge. The Z1 Auto is an auto-cpap machine that actually adapts to your breathing requirements thousands of times per night. By reacting to your requirements- rather than just delivering one constant pressure- the Z1 Auto delivers therapy at lower overall pressures and delivers a better, more natural breathing experience.

Very quiet
For a travel cpap the Z1 Auto is very quiet. The FDA testing revealed a sound level of 26dB using the standard testing methods although we have heard of slightly louder results from users.

Extremely light. Only 10.4 oz
The Z1 Auto is the lightest auto-cpap machine available anywhere. At only 10 ounces it is a great everyday machine that is also ideal for travel.

Optional integrated battery
The Z1™ Auto cpap 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. If you would like to purchase the Z1 Auto with an included PowerShell, just let us know.
