Complete Guide to the ResMed AirMini AutoSet: the World's Smallest Travel CPAP
Do you have sleep apnoea and refuse to leave your CPAP treatment at home when travelling? The ResMed AirMini AutoSet was built for you. Weighing only 300 grams and measuring just 13.2 × 8.4 × 8.3 cm, it is the most compact CPAP machine in the world. This complete guide covers everything you need to know before buying or travelling with your AirMini.
Why travel with a CPAP?
Sleep apnoea does not take holidays. Interrupting your treatment even for a few nights can bring back symptoms: daytime sleepiness, morning headaches, irritability and increased cardiovascular risk. Yet carrying a full-size CPAP machine on a plane, in a hiking backpack or in cabin luggage can feel burdensome.
Here are the situations where the AirMini makes all the difference:
- Air travel: fits inside a personal item bag without exceeding luggage limits
- Hotel stays: discreet, easy to place on the bedside table, universal power supply (100-240 V)
- Camping and hiking: lightweight, compatible with portable battery packs (not included)
- Train or car journeys: ready to use in seconds
- Second device strategy: keep your AirSense 11 at home and always have the AirMini in your travel bag

Mask Compatibility: What You Must Know
The AirMini uses a proprietary connector different from standard CPAP machines. It is only compatible with a specific selection of ResMed masks:
- AirFit F20 (full face mask)
- AirTouch F20 (foam full face mask)
- AirFit P10 (nasal pillows mask, ideal for travel)
- AirFit N20 (nasal mask)
- AirFit N30 (low-profile nasal cradle mask)
HumidX Humidification: How It Works
One of the main constraints of travelling with a standard CPAP is the water tank: heavy, bulky, and prohibited in cabin luggage (liquids rule). The AirMini solved this with the HumidX system.
The HumidX is a small hygroscopic foam cartridge that fits directly into the tube connector. It captures moisture from your exhaled breath and returns it on your next inhale - no water, no extra electricity, no tank. Two versions are available:
- HumidX standard: for temperate climates (normal ambient humidity)
- HumidX Plus: for dry environments (pressurised aircraft cabin, desert climate, continental winter)
HumidX cartridges should be replaced approximately every 30 days. Pack a few spares when travelling.
Flying with Your CPAP
Under IATA guidelines, a CPAP machine is classified as a medical device and is accepted in the cabin in addition to your standard carry-on baggage on most airlines. Key points:
- Carry a medical letter from your doctor or sleep specialist confirming your need for CPAP therapy
- The AirMini has a universal power supply (100-240 V) - no voltage converter needed, only a plug adapter for the country you visit
- Since no water tank is used, there is no issue with liquid restrictions at security
- Place the AirMini in a separate tray at security screening, like a laptop
AirMini App vs myAir: What Is the Difference?
The AirMini does not use an SD card. All data is transmitted via Bluetooth directly to the AirMini app on your smartphone. The app gives you access to:
- Daily therapy score (similar to myAir)
- Residual event index (AHI)
- Large leak frequency
- Usage time
- Comfort settings (SmartStart, AutoRamp, pressure relief)
Data is also synced to the ResMed AirView cloud platform, allowing your provider or physician to access your results remotely if you grant them access.

Who Should Buy the AirMini?
The AirMini AutoSet is not intended to replace a full home CPAP for most patients. It is ideal for:
- Patients already treated at home with a full CPAP (AirSense 11, DreamStation 2...) who want a lightweight travel device
- Frequent travellers: consultants, sales representatives, flight crew
- Outdoor enthusiasts: hiking, camping, expeditions in remote areas
- Patients wanting a second device so they never have to move their main CPAP
- Expats looking for a device compatible with all world voltages and easy to carry

The AirMini AutoSet is primarily designed as a travel CPAP or second device. It delivers the same AutoSet therapy as ResMed home machines (4 to 20 cmH2O) but has neither an active heated tube nor a water tank. For daily home use, a full-size CPAP such as the AirSense 11 offers superior comfort. The AirMini can still serve as a single device for patients who travel almost constantly or prioritise absolute portability.
CPAP is a class IIa medical device: a prescription is recommended, ideally issued by a sleep specialist who has confirmed obstructive sleep apnoea. At VivaRespire, we systematically request a prescription when ordering an AirMini, in the interest of patient safety. For full details on out-of-convention purchase conditions, see our CPAP prescription Belgium without INAMI page.
HumidX is a hygroscopic foam cartridge built into the AirMini tube connector. It captures moisture from your exhaled breath and returns it on the next inhale, with no water and no extra power. The standard cartridge suits temperate climates; HumidX Plus is recommended in aircraft cabins, continental winters or dry environments. Plan on replacing the cartridge roughly every 30 days. Carry spares for longer trips.
The AirMini uses a proprietary ResMed connector. It is only compatible with AirFit F20, AirTouch F20, AirFit P10, AirFit N20 and AirFit N30. Masks such as AirFit F40, Evora (Fisher & Paykel), DreamWear (Philips) and any other generic mask are NOT compatible, even with an adapter. Check your mask model before purchase and plan for a dedicated tube kit if needed.
The AirMini draws very little power: with a suitable portable battery (12 V DC or high-output USB-C PD), expect roughly one to two full nights per charge, depending on therapy pressure and HumidX usage. Medistrom Pilot 24 or IATA-approved 100 Wh power banks are the most common options. ResMed does not sell an original AirMini battery: always verify electrical compatibility before purchase.
Yes. Under IATA guidelines, a CPAP is a recognised medical device and is accepted in the cabin in addition to standard carry-on luggage on most airlines. Carry a medical letter from your doctor, present the device in a separate tray at security and keep any battery in the cabin (never in the hold). The AirMini is ideal for flying thanks to its universal 100-240 V power supply and the absence of a water tank subject to liquids restrictions.
No. VivaRespire operates out of the INAMI convention: devices sold on our site are not covered by reimbursement. The INAMI convention only covers CPAP devices made available (on loan) by an accredited sleep centre. The AirMini is most often purchased as a second travel device by patients already in convention for their home CPAP. For details, see our CPAP reimbursement in Belgium guide.
The AirMini has no built-in battery: it runs on mains power (100-240 V) or via a compatible external pack. This is what allows its extreme compactness (300 g). If you need autonomy for camping or long-haul flights, plan a separate portable battery sized to your therapy pressure and target nights. A 12 V DC pack such as the Medistrom Pilot 24 typically powers the AirMini for one to two nights depending on settings.
