I've been using a CPAP machine for about 19 years, luckily only had to different machines. My wife and I are at that age where we like to take long weekends on our bike and are venturing overseas for our vacations. While my current machine is much smaller than my first, it's still large enough to be a pain to pack up and travel. It consumes a lot of room and is cumbersome in the TSA lines.
Does anyone have any suggestions for a "travel size" machine?
