Here’s some good advice you don’t want to doze through: If you need a CPAP machine to control your sleep apnea, keeping it clean when you’re traveling is just as important as keeping a sanitary unit at home. I’ve used a CPAP machine for nearly a decade now, so I’ve been able to fine-tune the gear I bring along with me on vacations and road trips. These items don’t take up nearly as much space as your home maintenance tools, so traveling with your CPAP should be as safe as it is painless. While CPAP machines themselves require a doctor’s prescription, many cleaning and replacement supplies are available for purchase online. Here are four items I highly recommend you add to your travel kit.
