Full comparison of AirMini, Breas Z2 and Transcend Micro

Traveling with a CPAP machine should never be an obstacle to your well-being. Thanks to the new generation of travel CPAP devices, it's now possible to continue your sleep apnea therapy anywhere in the world , without the burden of a bulkier, traditional machine. Whether you're a business traveler, a camper, a road trip enthusiast, or a globetrotter, there's a compact and lightweight CPAP machine to suit your needs.
At La Boîte à CPAP , three models stand out: the ResMed AirMini , the Transcend Micro , and the Breas Z2 Auto . Each offers a unique experience tailored to different types of travelers. In this comprehensive guide, we review their strengths, features, included accessories, and key differences.
Travel CPAP machines: what you need to know before choosing
Before comparing the models, it is important to note one common characteristic: None of the three devices have an integrated water humidification chamber.
Travel CPAP machines instead use HME (Heat Moisture Exchange) filters that retain the natural moisture from your breath to replicate a form of waterless humidification.
This solution is extremely practical when travelling, particularly on a plane, in a backpack or when access to distilled water is limited.
1. Transcend Micro – The world's smallest CPAP, designed for frequent travelers

The Transcend Micro is the most compact travel CPAP machine on the market. About the size of a tennis ball, it easily fits into any bag. It's especially popular with minimalist travelers, campers, and anyone who needs a discreet and lightweight CPAP for frequent travel.
Despite its tiny size, it offers stable and comfortable therapy. The included WhisperSoft™ silencer helps reduce noise and makes the experience much more natural.
Compatibility
Unlike the AirMini, the Transcend Micro is compatible with all universal CPAP masks , allowing you to use your preferred mask without restriction. This freedom is greatly appreciated by users who do not wish to change equipment.
Main features
The Transcend Micro isn't just small; it's also surprisingly powerful. It offers a stable auto-adjustment mode, a soft start, comfortable pressure, and features designed to make therapy enjoyable even on the go. The included WhisperSoft™ silencer significantly reduces noise, greatly improving nighttime comfort for you and your partner.
What the device includes (value $1100)
-
Complete device programming
-
2-year warranty

PureFresh™ air filter, 6-foot AirFlex™ tubing , AC Power Adapter, WhisperSoft™ Silent
The Transcend Micro is an ideal choice for those seeking absolute portability while retaining their current mask.
2. ResMed AirMini – The most efficient compact CPAP

The ResMed AirMini is the world's most popular travel device. It combines ResMed's renowned stability technology, excellent nighttime performance, and a comprehensive mobile app to track your therapy in real time.
The AirMini is the ideal travel device for those who want a compact CPAP machine without compromising on treatment quality. While it's slightly larger than the Transcend Micro, it remains incredibly lightweight, quiet, and easy to carry.
Main features
The AirMini uses an advanced treatment algorithm based on the performance of the AirSense series. The device supports AutoSet, AutoSet for Her, and fixed CPAP mode, in addition to offering high-performance HME humidification technology. The mobile app allows you to track your results, AHI, leaks, and usage hours, making the AirMini as comprehensive a therapy tool as a standard device.
Compatibility
The AirMini is compatible only with certain ResMed masks (AirFit P10, N30, N20, and F20) designed to accommodate its HME humidification technology. A specific mask is therefore required, but this ensures optimal performance.

-
Unlimited follow-up with our respiratory therapists (in clinic or via telemedicine)

3. Breas Z2 Auto – The versatile CPAP, compatible with almost everything

The Breas Z2 Auto is known for its wide compatibility, ease of use, and excellent value. It offers stable and comfortable therapy thanks to Z-Breathe™ technology, which naturally reduces pressure during exhalation, making breathing easier and more natural.
The Z2 is slightly larger than the Transcend Micro, but remains extremely portable, lightweight, and easy to carry. Its very low noise level and stable operation make it a reliable device for regular users.
Main features
The Z2 Auto uses Z-Breathe™ technology, which reduces pressure during exhalation for increased breathing comfort. The device automatically adjusts the pressure as needed throughout the night, ensuring stable therapy comparable to that of a standard CPAP machine. It also features intelligent leak detection and a very low noise level.
Compatibility
The Breas Z2 is fully compatible with all universal CPAP masks , offering great flexibility, especially for those who wish to keep their current mask.
Humidification
Like its competitors, the Z2 uses HME cartridges to replace water humidification.
