Transcend Micro Travel Auto CPAP
Weighing under 0.5 lbs (219.5 g) and measuring less than four inches (9.1 cm), the Transcend Micro™ is the smallest and lightest travel CPAP available on the market. The Transcend Micro CPAP is designed to make sleep apnea therapy more convenient and portable.
With big things packed into this small device, the Transcend Micro meets the needs of travel CPAP users. These include quiet operation, auto-adjusting pressure, and the flexibility to add on a range of comfort accessories, including a heat moisture exchanger (HME) for waterless humidification. Planning and packing for your next getaway adventure is easier than ever with the new Transcend Micro.
Detailed Features
Quiet Operation
The Micro features unique air-bearing blower technology coupled with built-in sound and vibration dampening. The result is a quiet, restful night of sleep for users and bed partners alike. The Transcend WhisperSoft Muffler (included) will quiet your Micro even further. Attach it to the machine with the standard 6 ft tubing for extra comfort.
Compatible with any CPAP Mask
The Transcend Micro travel CPAP is compatible with any CPAP mask. Simply connect your mask to the included Transcend Micro AirFlex 6-foot hose or the Transcend Standard 6-foot hose.
Note:The Transcend WhisperSoft Muffler and its short custom tube is required to connect the Transcend Standard 6-foot hose to the machine.
Auto Start/Stop Feature
The Micro comes equipped with Auto Start/Stop features and starts therapy automatically when you breathe into your CPAP mask. The machine will automatically stop therapy after the mask is removed. Users can also manually start and stop therapy via the power button.
Unplug and Sleep Anywhere with More Power Options
The Transcend Micro comes with an AC (wall) power adapter for when you’re at home, in your cabin, or at a hotel. The Micro can also be used with the Transcend PowerAway™ P8 portable battery as an ideal option for camping, flights, or travels to remote locations off the grid.
Waterless Humidification
The Transcend Micro AirMist HME waterless humidification system is designed to easily add heat and humidity to your sleep therapy without the need for a bulky humidifier. The AirMist (sold separately) works with either tubing provided with the machine.
Adjustable Ramp Technology
The Transcend Micro features Ramp technology to help you fall asleep more comfortably. Ramp starts therapy at a lower pressure which gradually increases over the set Ramp Time until it reaches the prescribed therapy pressure. The Ramp feature is adjustable, so you can fine-tune your Ramp Time or turn it off altogether, depending on your comfort level.
AirRelief Exhalation Pressure Relief
The Micro is also equipped with the AirRelief feature which reduces pressure on exhalation to help you breathe more comfortably. Three AirRelief settings are available - 1, 2, or 3. The higher the setting, the greater the exhalation relief the Micro provides. AirRelief can also be turned off.
Keep Your Equipment Dry with Ease
Easily remove excess moisture from your mask and tubing with the Micro’s convenient drying mode. Upon waking up, just activate the 30-minute drying cycle on the unit and the Micro will start moving a steady stream of air through your hose and mask. The drying mode removes excess moisture in your hose and mask which can be a breeding ground for bacteria.

Sleep Data Tracking
Track your sleep data and monitor your therapy progress via the Transcend MySleepDash app (iOS/Android) and the Transcend desktop software (Windows only, not compatible with Mac computers).
The MySleepDash app* allows you to track your usage hours, mask leak, AHI/breathing events per hour, and mask removal for your last 24 hours, 7 days, 30 days, 90 days, and year of use. You can also review your therapy pressure settings and adjust comfort settings. Transcend's MySleepDash app also simplifies compliance reporting, allowing users to view, share and download detailed compliance reports.
If you encounter any issues with your Micro, you can easily find answers to common problems in the app's detailed troubleshooting guide. If the problem persists, simply tap "Report an issue" to send the reported issue and machine diagnostic data to Transcend Customer Support. A Transcend customer support representative will contact you after analyzing the data.
Those who prefer not to use the app can still view their detailed sleep data, change comfort and pressure settings, and generate compliance reports via the Windows-compatible Transcend desktop software. A USB-C cable is required to connect the Micro to your desktop computer.
*The app is fully functional on Micro devices with firmware version 1.2.0 or greater. The app has limited functionality when used with Micro devices with earlier firmware versions. Limited functionality includes, but is not limited to, no ability to change comfort settings, limited diagnostics sent through 1-Click Troubleshooting, etc.
Note: You do not need the app to operate the Transcend Micro.

I was thrilled to give this tiny travel CPAP a go! I love the simplicity of this device, and you can’t beat the size - it easily fits in a purse or travel bag. It is easy to use, and when paired with the matching battery, you have the whole package. Just add the slim hose, use any mask of your choice, start breathing through the mask to start the unit, and you’re off to the races. Our team will program your Micro based on your prescription prior to shipping, so your Micro comes set up and ready to go.
The drying function on this device is quite impressive. Just push the drying button to activate a 30 minute drying cycle that removes moisture to help control bacteria growth. What a handy feature!
If you're like me and can't use CPAP without a humidifier, the Micro has you covered. The Transcend Micro has a waterless humidification kit (AirMist Kit) that captures the moisture from your breath and recycles it back to you to provide humidification. The kit is sold separately for a month's supply.
Travel CPAPs can be noisier than home units because there is less room for insulation. Given the Micro's small size, I anticipated it would be louder than my home machine. The technical data specifies a noise level of 27 decibels, which is identical to my home device.
Well, I did find it slightly louder, especially on inhalation. However, this was not a problem for me. If you are sensitive to noise, you might want to pack a pair of earplugs in your travel bag. It's worth noting that the Micro comes with a Muffler Kit in case you need to dampen the sound.
Overall, I am very impressed with this tiny machine. I always recommend our clients have a backup device that travels well, and the Micro fits the bill!
