Always empty your humidifier of water before packing your CPAP equipment in your carrying case.
Research your destination to determine whether power adapters for plugs are required in order to operate North American electronics (your CPAP machine).
If you are flying with your CPAP, you can bring your CPAP machine on the airplane with you and it will not count as one of your carry-on items. Never check your CPAP machine because through normal luggage handling procedures, it can be easily broken.
When flying, if possible, bring your prescription. While not required, it may be useful in providing your need for CPAP if ever in question.
Pack CPAP wipes and cleaners to ensure you’re able to continue to keep your CPAP mask and equipment clean.
Portable batteries and power accessories can allow you to continue your CPAP therapy during unexpected power outages, or during travel.
