How do you take a CPAP machine through airport security?

A nebulizer, CPAP, BiPAP and APAP must be removed from its carrying case and undergo X-ray screening. Facemasks and tubing may remain in the case. You may provide a clear plastic bag to place the device through the X-ray.



Taking a CPAP machine through security in 2026 is a standard process, as TSA and international agents see these medical devices daily. You should carry your CPAP in its dedicated travel case as a carry-on item, as it does not count toward your baggage limit on most airlines due to its status as a medical device. At the security checkpoint, you must remove the main machine from its carrying case and place it in a separate bin, similar to a laptop. It is a "pro-tip" to place the machine in a clear plastic bag before putting it in the bin to keep it sanitary. While not strictly required, having a medical equipment luggage tag or a copy of your prescription can help expedite the process if an agent has questions. If the machine requires a "swab" for explosives, don't worry—this is a routine procedure. Always allow an extra 5–10 minutes for this screening to ensure you aren't rushed before your flight.
