Summer travel is one of those things that should feel uncomplicated. But if you use a CPAP machine, you know the anxiety that sets in the moment you start packing. What if security pulls it? Where do I find distilled water in Croatia? What happens if there's no power at the campsite?
Here's the reality: traveling with CPAP isn't that hard. It just takes a bit more prep than throwing clothes in a bag. Whether you're flying somewhere tropical, road-tripping through the Rockies, or camping in the backcountry, this guide covers everything you need to sleep well away from home.
Before You Go
Check your gear at least two weeks out. Inspect your mask cushions, tubing, filters, and headgear. If anything looks worn, replace it now, not the night before your flight. Ordering parts takes time, and traveling with a leaky mask is miserable.
Grab a prescription or doctor's note (Optional). This isn't strictly required at most Canadian airports, but it's worth having. Some international customs officers ask, and it speeds things up at security checkpoints. Keep it in your CPAP bag, not your checked luggage.
Check your machine's voltage specs. Look at the label on your power brick. If it says 100–240V, you're fine internationally with just a plug adapter. If it says 120V only, you'll need a voltage converter. Most machines made in the last five years are dual-voltage.
Make a packing checklist and stick to it. CPAP, mask, tubing, power cord, adapter (if needed), distilled water, wipes. The items you forget are always the smallest ones.
Flying with Your CPAP
This trips people up more than it should, so let's be clear: your CPAP machine is a medical device. In Canada and the US, it does not count as a carry-on item. You can bring it on the plane in addition to your regular carry-on and personal item — at no extra charge.
At security:
- Remove the machine from its bag and place it in a separate bin. You don't have to take out your mask or accessories, just the machine itself.
- Using a clear plastic bag around the machine is a smart move — it protects it from contamination on those TSA trays.
- Some airports will swab your machine for explosive residue. That's normal. Stay calm, it takes about 30 seconds.
- A "Medical Device" luggage tag on your bag helps staff recognize what they're dealing with before they even open it.
Distilled water on flights: You can bring up to 100ml (about 3.4 oz) of distilled water in your carry-on as a medically required liquid. It needs to be clearly labeled and may get extra screening. For anything larger, pack it in checked luggage — or just buy it at a pharmacy once you land. Most pharmacies worldwide carry it.
If you want to avoid the water question entirely, a travel CPAP with waterless humidification (like the ResMed AirMini with HumidX) sidesteps the problem completely.
On the plane: Turn your humidifier off before you fly — turbulence and cabin pressure can cause water to slosh into your tubing. Enable airplane mode if your machine has it. Let the flight crew know you'll be using a medical device; most will happily accommodate you.
Camping and Off-Grid Travel
Camping with CPAP used to mean hauling a car battery and crossing your fingers. Today, it's a lot more manageable.
Battery options: A purpose-built CPAP battery pack is the easiest solution. Look for one that's FAA-approved (if you're flying to your campsite) and compatible with your specific machine model. A rough calculation: a 500Wh battery running a 40-watt CPAP will last roughly 12 hours, though heated tubing and humidification will drain it faster.
Conserve power when you're off-grid:
- Turn off heated tubing
- Disable the humidifier or use waterless humidification
- Use a DC cord instead of an inverter — it's more efficient
Some batteries can recharge via solar panels, which is worth considering for multi-night trips.
Distilled water in the wilderness: Never use lake, stream, or tap water in your humidifier — even filtered. It introduces minerals and bacteria that damage your machine over time and may void your warranty. Pack enough distilled water for the trip, or turn the humidifier off and use a waterless option like a heat-moisture exchanger (HME).
Heat and humidity: Summer camping means warm nights. Heat can affect how your machine performs and speeds up bacterial growth in tubing and the humidifier tub. Store your machine somewhere dry and shaded, never in a tent that bakes in afternoon sun. After each use, air out your mask and let the tubing dry thoroughly.
Altitude: If you're heading into the mountains, most modern CPAP machines adjust pressure automatically. Older models may need to be manually adjusted. Check your manual or call your equipment provider before you go.
Road Trips and RV Travel
Road tripping is the most forgiving travel format for CPAP users. You have a car outlet, you can pack full-sized supplies, and you're not at the mercy of airline rules.
Power: A DC converter lets you plug your CPAP directly into your vehicle's 12V outlet. Great for quick overnight stops or campgrounds without hookups.
Humidity adjustments: Very humid environments (like coastal BC in summer) may actually let you lower your humidity setting. Dry regions like the Interior might call for more humidification. Adjust as you go and pay attention to how you feel.
Storage: Keep your machine somewhere stable and temperature-controlled inside the vehicle. Don't leave it in a hot car or storage bay — prolonged heat exposure can damage internal components.
Hotels and Short-Term Rentals
Hotels are the easiest scenario. Request distilled water from the front desk or pick some up nearby. Always run a quick search before your trip for "pharmacy near [destination]" so you know where to go if you run low.
A few other things worth doing:
- Ask housekeeping not to move your CPAP or unplug it
- Use the provided "Do Not Disturb" sign during setup or if you're taking a rest during the day
- Keep your machine and accessories off wet bathroom surfaces — moisture is the enemy of motor longevity
Should You Bring a Travel CPAP or Your Regular Machine?
If you travel regularly, a dedicated travel CPAP is worth considering. Machines like the ResMed AirMini or Transcend Micro are compact, quiet, and designed specifically for travel. The AirMini weighs just 300 grams and uses HumidX waterless humidification, eliminating the distilled water issue altogether.
That said, if you only travel a few times a year, your regular machine works fine. Modern full-size CPAP machines are more travel-friendly than they used to be, and most come with a carrying case.
Either way, the most important thing is simple: bring it. Skipping even a few nights of CPAP therapy can lead to fatigue, increased blood pressure, and a return of apnea symptoms — none of which make for a good vacation.
Quick Reference: Summer CPAP Travel Checklist
- CPAP machine in a dedicated carry bag with "Medical Device" tag
- Mask, tubing, headgear (check for wear before packing)
- Power cord + plug adapter if traveling internationally
- CPAP battery or DC cord (for camping or off-grid travel)
- Distilled water (small bottle for carry-on; larger supply for camping/road trips)
- CPAP wipes for daily cleaning on the go
- Prescription or doctor's note
- Spare mask cushion and filters
Sleep apnea doesn't take a summer break. But with a bit of prep, neither does your therapy.
