Product Description
Lightly Used Transcend Micro 510 Auto CPAP
A Complete Travel CPAP With Waterless Humidification, Hard Shell Case, and Substantial Remaining Warranty
Get the world’s smallest travel CPAP at a fraction of the price. These Transcend Micro 510 Auto CPAP machines are lightly used 30-day customer returns. Because they were returned so quickly, they are in excellent condition and still carry the vast majority of their original 3-year manufacturer warranty.
At just 0.48 lbs and 3.6” in diameter, the Micro 510 is about the size of a tennis ball — 26% lighter than the leading travel CPAP. Whether you’re on a cross-country flight, camping off the grid, or just want a smaller nightstand footprint, this machine delivers full-power therapy without the bulk.
The auto CPAP algorithm adapts breath-by-breath within a pressure range of 4–20 cmH₂O. Comfort features like GentleRise™ ramp, AirRelief™ exhalation relief, and SleepStart™ auto on/off make it just as comfortable as a full-sized machine. Plus, the included WhisperSoft™ Muffler keeps noise to just 25–29 dB — quieter than a whisper.
Works with any CPAP mask with a standard 22mm connection — no proprietary adapters needed. Just plug in your favorite mask and go.

Frequently Asked Questions
These units are 30-day customer returns. They were briefly trialed and returned, meaning they are in excellent, like-new condition. Buying an open-box unit allows you to get the world's smallest travel CPAP at a significant discount.
Yes, the Micro 510 features a universal 22mm connection. You do not need any special proprietary adapters to connect your favorite mask.
The machine includes an AirMist™ HME (Heat Moisture Exchanger) starter kit. The HME cartridge sits between your mask and the hose, capturing the moisture from your exhaled breath and recycling it when you inhale. Note: AirMist cartridges should be replaced 7 days after opening.
While the machine itself connects to any mask, the AirMist HME feature is not compatible with masks that connect at the top of the head (like the ResMed AirFit N30i or Philips DreamWear) or masks that use a short front hose (like the AirFit F40, P10, or Nova Micro).
Yes. The Micro 510 is FAA-approved for in-flight use. Because it is a medical device, it does not count toward your carry-on luggage allowance. It also includes a universal 100–240V power supply, making international travel easy.
No, the battery is not included in the box. If you plan to camp or go off the grid, you will need to purchase the optional PowerAway™ Battery separately, which provides 2+ nights of therapy per charge.
No. The Micro 510 requires specific Woven or Hypoallergenic filters and uses the redesigned TransFlex™ hose. The older black foam PureFresh filters and AirFlex hoses from the original Micro are not compatible with the 510.
