CPAP at TSA Security Screening: What to Expect
TSA allows CPAP machines in carry-on and checked bags. In a standard lane the device can usually stay in its case for X-ray, though an officer may ask you to remove it; with TSA PreCheck you can leave the device, mask and tubing in the case and in your bag.
What TSA says
TSA's guidance for nebulizers, CPAPs, BiPAPs and APAPs says they are allowed in carry-on and checked bags with special instructions. In standard screening, the devices, masks and tubing may remain in their carrying case for X-ray, but an officer may require you to remove them from your carry-on.
With TSA PreCheck, you can leave the devices, masks and tubing in their case and in your carry-on during X-ray. The final decision rests with the officer at the checkpoint.
Before you get to the checkpoint
Empty the water tub. Put the mask and tubing in a clean, clear bag so they stay clean if the machine is handled. Tell the officer you have a CPAP before screening starts.
Leave a little extra time at the airport, since an officer may want to inspect the device more closely.
During screening
Officers may swab the device for explosives traces or look more closely at it. That is routine. You can ask them to change gloves before touching your mask, and to keep the mask in its bag.
TSA's CPAP guidance covers nebulizer liquids, not humidifier water, so it is simpler to buy distilled water at your destination than to carry it through security.
Batteries
TSA says devices with lithium metal or lithium ion batteries should go in your carry-on.
Check your airline's rules for battery size limits, especially for large external batteries.
Supplies that can help
A padded bag that protects the machine, mask, tubing and power supply in transit.
A battery pack that runs a CPAP machine without mains power, for camping, power outages or long flights.
