  • Take the machine out of its bag at the checkpoint and place it directly in a bin; officers may swab it for explosive traces.
  • Leave the mask, tubing, and humidifier chamber in the case — only the machine needs to come out.
  • A clear plastic bag over the device is acceptable if you do not want it touching the bin.
  • Empty the humidifier chamber before you fly; water sloshing in the chamber can damage the motor.
  • Distilled water is a medically necessary liquid — declare it and it can exceed 3.4 oz.
