I travel >100,000 miles a year and I keep my Z1 in my suitcase so I never forget it. I tell my domestic and international sleep apnea patients that not only do I recommend the Z1 for treatment of their OSA, I use it myself and wouldn’t go anywhere without it!

I am using your Z1 CPAP machine for travels, and really enjoy the product. I think it is outstanding!

I've avoided taking a CPAP on my travels because I have enough to lug with a rollaboard and a briefcase. I bought this little jewel when it was first available and I am thrilled with it. It works great, adjusts to my breathing, and provides me with a great night's sleep on the road. I am no longer exhausted because of poor sleep and I can pack it in my rollaboard easily. Thank you, Human Design. Brilliant.

The Z1 is the world’s smallest, lightest, most integrated cpap system.
