The cpap traveler's new best friend.

The Z1 Auto is FAA approved for in-flight use:-)


This is the BEST CPAP machine I have ever used and I have been using one since 1983! I bought my first Z1 about a year ago to use for travel only. I bought another one today to replace my bedside unit and to back-up my travel unit because it is so much better. Overall, I have owned and used 9 different CPAP machines. Your Z1 is the best!

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.

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