Preparing Your CPAP for Travel
Importance of CPAP Therapy During Travel
Sleep apnea doesn’t take vacations, and neither should your treatment. A study in the Canadian Journal of Respiratory Therapy found that travel often leads to decreased CPAP adherence, negatively impacting sleep quality and daytime functioning. Consistent therapy is crucial for cardiovascular health, energy levels, and overall well-being.
Checking CPAP Equipment for Wear and Tear
Before your trip, inspect your equipment for wear. Look at your mask cushion, headgear, tubing, filters, and humidifier chamber. Cracks, discoloration, or weak seals can affect the quality of your therapy. It's smart to replace worn components in advance, and Your CPAP Shop offers a reliable source for compatible parts and accessories across Canada.
Ensuring CPAP Equipment Is Dry to Prevent Mould
Moisture inside your CPAP device or humidifier chamber can promote mould growth. To prevent this, wash all parts using a mild, unscented soap and distilled water, then allow them to air dry completely at least 24 hours before packing. According to infection control guidelines published in Chest, complete drying is essential to avoid bacterial contamination in CPAP components.
Packing Essentials
A sturdy CPAP-specific travel case protects your device during transit and helps organize accessories. Essential items to pack include:
-
Spare tubing and mask cushions
-
Extra CPAP filters
-
Copy of your prescription
-
Small bottle of gentle soap for manual cleaning
-
Backup power source, if needed
Keep your CPAP machine in your carry-on luggage. This ensures it stays with you in case your checked baggage is delayed. Your CPAP Shop also stocks travel kits explicitly designed for CPAP users.
Managing Distilled Water for CPAP
Importance of Using Distilled Water in CPAP Machines
Distilled water is crucial because it lacks the minerals and impurities found in tap or spring water, which can damage your machine and cause health risks.
Guidelines for Carrying Distilled Water on Flights
If you’re flying, you can carry up to 100 ml of distilled water in your carry-on, following TSA’s liquid restrictions. Larger amounts should go into your checked baggage, tightly sealed to prevent leakage. Remember to inform TSA officers that the water is for medical use.
Alternatives to Distilled Water When Travelling
When distilled water isn’t available, you can temporarily:
-
Use bottled water with low mineral content (e.g., reverse osmosis-filtered water)
-
Boil tap water for 15 minutes and allow it to cool
-
Travel with a compact water distiller if you need reliable access for long stays
Bottled Water and CPAP
Bottled water may be used in emergencies, but it is not a long-term substitute. Tap and spring water contain minerals that can corrode the humidifier chamber and foster bacterial growth. If you do use bottled water temporarily, clean your chamber thoroughly and switch back to distilled water as soon as it's available.
Many travellers find that local pharmacies like Shoppers Drug Mart, Rexall or grocery chains often carry distilled water. You can also ask hotel staff or concierges for assistance. Your CPAP Shop recommends travelling with a small collapsible water bottle to store distilled water once you've sourced it.
Navigating Airport Security with CPAP
TSA Guidelines for CPAP Machines
CPAP devices are categorized as medical equipment, which means they don’t count against your carry-on limit. As you approach security, inform the officer that you're carrying a CPAP machine.
Place the machine in a separate bin for X-ray screening. Accessories should be placed in a clear plastic bag. If you're concerned about hygiene, you can request that TSA officers use new gloves and avoid direct contact with the device.
Airline Policies and CPAP
Airline policies vary, so check with your carrier at least 48 hours before departure:
-
Notify the airline in advance if you plan to use your CPAP during the flight
-
Bring a prescription and a manufacturer’s compliance letter
-
Know your power options, some airlines offer in-seat power while others do not
Many modern travel CPAP machines, available at Your CPAP Shop, are approved and explicitly designed for in-flight use.

Power Supply and CPAP
Using a Battery Pack for CPAP
If you’re camping, flying long distances, or staying somewhere with an unreliable power grid, bring a CPAP battery pack. These batteries are often airline-compliant and can run your machine for a full night. Check the specifications for your device to ensure compatibility.
Packing a Voltage Adapter for International Travel
For international travel, pack a high-quality voltage adapter and the appropriate plug converter. Most newer CPAP machines support dual-voltage use, but always verify in advance.
Investing in a DC Converter for Power Options
A DC converter allows you to plug your CPAP into a vehicle’s 12V outlet, ideal for road trips and RV travel. You can find travel-specific converters and accessories through Your CPAP Shop, which carries both branded and universal solutions.
Portable CPAP Options
For those who travel frequently, a compact CPAP machine offers major convenience. Models like the ResMed AirMini and HDM Z2 Auto are small enough to fit in a carry-on, operate quietly, and support waterless humidification systems. These features eliminate the need for distilled water in some cases, though always consult with your sleep therapist before switching devices.

Case Study: Frequent Travellers CPAP Strategy
Frequent travellers with obstructive sleep apnea often follow a structured approach to CPAP therapy on the road. Many pack a collapsible water container for distilled water sourced from local pharmacies, with low-mineral bottled water as a backup. They rely on a universal power adapter and a compliant battery for uninterrupted, in-flight use of travel-sized CPAP machines. For hygiene, they use CPAP wipes and mild soap in accordance with Canadian Thoracic Society cleaning recommendations.
