Quick answer: an auto CPAP is a full-size home machine that adjusts pressure through the night and usually has a heated humidifier. A travel CPAP is a smaller, lighter machine designed for trips, often without a built-in water humidifier. For nightly use at home most people choose an auto CPAP; a travel CPAP suits people who fly or travel often. Both need a prescription and a mask that fits.

Which one should you choose?
- Choose an auto CPAP if you will use it at home every night, live in a dry or air-conditioned room, or prefer heated humidification.
- Choose a travel CPAP as a second machine if you travel several times a year, or if portability matters more than humidification.
- If you can only buy one machine, an auto CPAP is the safer all-round choice for most people.
Can you use a travel CPAP every night?
Yes, many travel CPAPs are designed for nightly use. Some users find waterless humidification less comfortable over long periods, especially with a dry nose or mouth, so talk to your doctor if you plan to use one as your only machine.
Flying with a CPAP
Most airlines treat CPAP machines as medical devices, but rules differ. Check with the airline before you fly, carry the machine in your hand luggage, and keep a copy of your prescription.
