Transcend Mini CPAP

Released in 2011, the Transcend Mini CPAP was the device that started it all.

Transcend EZEX

Next up, the Transcend EZEX Mini CPAP incorporates all of the handy features of the original Transcend in addition to Transcend EZEX pressure relief technology. The EZEX system is designed to drop in pressure when you exhale to allow you to breathe more easily during the night.

Tuck customer satisfaction rating: 89% (97 customer reviews)

  • EZEX exhalation pressure relief enhances breathing comfort by dropping pressure on exhalation while you sleep

Transcend AUTO

In addition to EZEX pressure relief, the Transcend AUTO Mini CPAP includes a self-adjusting pressure technology. Instead of sticking to one pressure, the auto-adjusting system monitors your breath throughout the night and increases or decreases pressure in response to events like apneas, mask leaks, and sleep position changes.

Tuck customer satisfaction score: 93% (342 customer reviews)

  • Auto-adjusting mode can monitor and make pressure changes according to needs on a breath-by-breath basis

Which Somnetics CPAP machine will work for me?

All three models of Somnetics Transcend CPAP machines are small and lightweight, making them ideal for travelers. Their solar power charger and backup battery options means that the Transcend CPAP are uniquely suited for camping trips and outdoor adventures where you might not have access to electricity.

Ultimately, choosing the right Transcend CPAP machine comes down to your personal preferences and sleep habits. If you find exhaling against conventional CPAP machines difficult or uncomfortable, you may want to choose either the Transcend EZEX or AUTO, both of which feature exhale pressure relief technology.

The Transcend AUTO model might be your best bet if you often have changing pressure needs during the night. For example, you should consider the AUTO edition if you tend to shift positions frequently when you sleep, since you will likely need a lower amount of pressure when sleeping on your side than when you sleep on your back. Similarly, you may want to go for the Transcend AUTO if you have seasonal allergies, since you may require more pressure at times of night or seasons when you are more congested. You may also want to choose the AUTO model if you drink or take certain types of sedative medications, as these can cause influxes in your pressure needs.
