The Z1 Auto | the lightest, ultra-small, travel auto cpap.

The Z1 Auto– with its proprietary breathing algorithm and sampling rate of several times per second– delivers extremely responsive and effective therapy at lower overall pressures than fixed-pressure cpap. The result is more responsive therapy and a more comfortable experience.

The Z1 Auto does not require a special mask and tube. Most people find they can use the mask they are most comfortable wearing. Note: masks that are designed to only fit a specific brand of cpap will not connect to the Z1. These masks are proprietary to that brand and must be used with that brand of cpap.

Going off the grid? Add on the PowerShell integrated battery pack and get a good night’s rest on a single charge.

Get maximum comfort every night, whether you are at home or in a tent in the middle of nowhere. The Z1 Auto is designed for you.

If you travel it is amazing too. No extra stuff to pack. For the first time in 6 years I didn't pack an extra bag to go out of town- it all fit in my carry-on!
