CPAP travel case
A padded bag that protects the machine, mask, tubing and power supply in transit.
Why it helps
A padded case keeps the machine and humidifier chamber from cracking and keeps all the small parts together. Under 14 CFR 382.121, US airlines must not count assistive devices toward a carry-on bag limit (ask your airline to confirm it treats your CPAP that way), and carrying it on avoids the risk of damage in checked bags. Many machines, including the AirSense 11, come with a travel bag.
How to choose
Choose a case sized for your machine with separate room for the mask, tubing, power supply and any battery, and a firm or padded shell. A case that opens fully makes TSA screening easier. If you also carry personal items in the same bag, the airline may count it as a regular carry-on.
Empty the humidifier chamber before packing. TSA says CPAP machines, masks and tubing may stay in their carrying case for X-ray screening but may be required to be removed from the carry-on bag. Lithium battery spares must stay in carry-on baggage.
Frequently asked questions
Does a CPAP count as a carry-on bag?
Under 14 CFR 382.121, US carriers must not count assistive devices toward a carry-on limit; confirm with your airline that it treats your CPAP as one. If the same bag holds other personal items, the airline may count it, so keep the CPAP in its own case.
Do I have to take my CPAP out at security?
TSA says CPAPs, masks and tubing may stay in their carrying case for X-ray screening but may be required to be removed from your carry-on.
Can I use my CPAP on the plane?
Under 14 CFR 382.27, a US carrier may require 48 hours advance notice and check in one hour before general check in to use a CPAP onboard. Ask the airline when you book. Manufacturers state whether a machine meets FAA requirements; ResMed's AirSense 11 guide, for example, says it does for all phases of air travel.
