At only 10 oz, the Z1 is a quantum leap in portable cpap.

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- an ultra-small, travel cpap.

Small enough for 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.
