Traveling with a CPAP machine might feel overwhelming if you’re flying for the first time, but the TSA makes specific allowances for medical devices—including CPAP equipment. Knowing what to pack, what to expect at security, and how to protect your machine can make the difference between a stressful trip and a smooth experience.
Let’s break down exactly what you need to know before boarding your next flight.
Is CPAP Allowed on Planes?
Yes. According to TSA guidelines for medical devices, CPAP machines are permitted through security and in-flight. The device is considered essential medical equipment and does not count toward your carry-on limit.
This means you can carry your CPAP separately, even if you already have two other bags.
What Happens at TSA Checkpoints with a CPAP?
When going through security, your CPAP will need to be removed from its carrying case and placed in a separate bin—just like a laptop. The machine will be visually inspected and sometimes swabbed for explosives.
However, you are not required to remove the tubing, mask, or humidifier chamber—only the main CPAP unit must be scanned.
Tip: Place your CPAP in a clear plastic bag before putting it in the TSA bin to protect it from surface contamination. The American Sleep Apnea Association recommends this as a standard hygiene practice.
TSA Cares: Free Assistance If You Need It
For travelers who feel anxious or need help with the screening process, TSA Cares is a free support program that offers assistance to those traveling with medical devices. You can call 72 hours ahead to request help at the checkpoint.
They can even assign a Passenger Support Specialist to guide you through the process privately if needed.
What to Pack in Your CPAP Travel Kit
Here’s a quick checklist of what to bring when flying with your machine:
CPAP Machine
Make sure it’s FAA-approved for in-flight use if you plan to use it during the flight.
Mask & Tubing
Clean and dry them before packing. Use a storage pouch to keep parts dust-free.
Power Supply
Bring your power cord and any international plug adapters if you’re traveling abroad.
Extension Cord
Airport hotel rooms don’t always have outlets nearby. An extension cord gives flexibility.
Backup Filters
Disposable filters can get clogged more quickly in dusty or dry climates.
Distilled Water (Check Airline Rules)
If you’re bringing water for your humidifier, use sealed containers and check for liquid limits. Some travelers opt to purchase distilled water after clearing security.
Cleaning Wipes
CPAP mask wipes are TSA-friendly and allow you to clean on the go.
Can You Use Your CPAP In-Flight?
Yes—but only with airline approval. Most modern CPAP machines, such as those from ResMed and Philips, are FAA-compliant and safe for use in the air. However, you must contact your airline ahead of time to request in-flight use.
Some airlines require documentation, while others simply ask for early notification. Be prepared with:
- A CPAP that runs on battery or DC power (if there’s no outlet on board)
- Airline-compatible battery packs, like Medistrom Pilot-24 Lite
- Extension cables or travel adapters if flying internationally
Important: Nebulizers and humidifiers are not permitted for use in-flight due to liquid content. Stick to dry use unless otherwise approved.
Packing Tips for Airport and Hotel Use
Use the Right Travel Case
Many CPAP machines come with a protective travel bag that includes compartments for cables, filters, and tubing. Use this bag instead of tossing the unit in your suitcase.
Label Your Equipment
Clearly mark your machine as medical equipment using a tag or label. This helps security personnel and airline staff identify it quickly and handle it appropriately.
Bring Documentation
While not required, it can help to carry:
- A letter from your doctor explaining your need for CPAP
- Device manuals showing FAA approval
- Manufacturer specs for in-flight use
These materials are useful if an agent is unfamiliar with CPAP rules or you need to clarify battery usage.
Can You Check a CPAP Machine?
Technically, yes—but it’s not recommended. The TSA and CPAP manufacturers both advise against placing your CPAP in checked baggage, as the device is fragile and could be lost or damaged.
By keeping it with you, you can also use it during long layovers or on overnight flights.
Distilled Water for Travel: What to Know
Many users rely on distilled water for their humidifiers. Here’s how to handle that when flying:
- Under 3.4 oz (100 ml): Allowed in your carry-on
- Larger bottles: Must be placed in checked luggage
- Best option: Buy distilled water at your destination or use bottled water for short trips (only if your device allows it)
ResMed recommends draining your humidifier before flights to avoid spills and potential damage.
Security Screening Questions to Expect
When going through TSA with your CPAP, you may be asked:
- What is this device used for?
- Does it contain any liquids?
- May we swab it for explosive residue?
Be calm and confident—TSA agents are trained to deal with medical equipment. If you’re concerned about cleanliness, request a glove change before they handle your machine.
Don’t Forget to Clean After You Land
Travel exposes your CPAP to new environments, from dusty hotel air to dry plane cabins. Once you reach your destination:
- Wipe down your mask and tubing
- Empty and dry your humidifier
- Store your device elevated on a nightstand—not on the floor or next to a vent
This CPAP travel hygiene guide can help you stay ahead of post-flight maintenance.
