What “Certified Pre-Owned” means
This isn’t a generic used machine. Every AirSense 11 we sell as Certified Pre-Owned goes through the same hands-on process:
You get the newest AirSense generation at a lower price than new — inspected before it ships, and supported by our U.S.-based team in Doral, FL.
The AirSense 11 AutoSet (Certified Pre-Owned) is an auto-adjusting CPAP (APAP, 4–20 cmH₂O) with a color touchscreen, an integrated HumidAir humidifier and myAir app connectivity over its built-in cellular and Bluetooth. American Oxygen inspects, tests and reconditions each unit, installs a new filter, and backs it with a 1-year warranty by American Oxygen. A prescription is required. It ships complete from Doral, FL with free U.S. shipping over $99 — and you can add any compatible CPAP mask at 10% off, plus genuine filters or heated ClimateLineAir tubing, at checkout.

Fast service and great shipping! The machine is louder than it should be – not sure if this is because it’s pre owned or if the water tank doesn’t have a good seal…
Gloria Gervitz –
Thank you so much for recommending this product. Excellent cloud connection, thanks American!
Gary Gaskin (verified owner) –
I’m a CPAP user and travel frequently.
I shopped for a travel/spare machine for that purpose.
I found a certified pre-owned/refurbished machine at American Oxygen at less than the price of a travel system.
Placed my order. It shipped fast. Arrived safely.
I set the machine up for a trial run and found that the ResMed 11 auto worked perfectly and best all my supplies were interchangeable.
Very pleased with the whole process.
Will be returning for supplies in the future.
Winning is good.
