The Z1™ is the world’s smallest, lightest, most integrated cpap machine. At only 10 ounces the Z1™ is a quantum leap in portable cpap. With an available battery solution called The PowerShell™, the Z1 is an excellent travel cpap that fits in the palm of your hand.

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

In development for more than three years, Human Design Medical 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, HDM whittled away every ounce of wasted space before arriving 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.


Very quiet.
The Z1™ only makes 26 dBA of sound during operation according to industry standard testing procedures. By cpap industry standards the Z1 is very quiet although some users do report higher perceived sound.

Extremely light. Only 10 oz
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.

Optional integrated battery
The Z1™ 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 for the z1 xpap machinesOne 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.

The Z1 is great travel machine that packs small and light. Add the PowerShell™ with its included battery module and you get a complete travel solution that offers cord-free power for any situation.
