This is a Certified Refurbished ResMed AirSense 11 AutoSet with HumidAir Heated Humidifier, ResMed's newest auto-adjusting CPAP platform, at a meaningful discount off the price of new. It is a great way to get the same AutoSet algorithm, integrated humidifier, and myAir app support as a brand new unit, at a lower price point.

Fully Cleaned, Disinfected, and Tested

All of our pre-owned CPAP machines are thoroughly cleaned, disinfected, and rigorously tested to confirm they're in good working condition before being offered for sale. Every machine we offer has less than 700 hours of usage.

Warranty Coverage

Every refurbished machine includes a 14 day warranty from GoCPAP.com, starting the day it's delivered by the shipper. After that, most machines still carry a portion of the original manufacturer's warranty. The exact time remaining on the manufacturer's warranty will be printed and included with your machine. Contact us anytime if you have questions or want to confirm how much manufacturer coverage is left on your specific unit.

Frequently Asked Questions

Do I need a prescription to buy a refurbished AirSense 11?

Yes. CPAP machines are regulated medical devices in the United States, so a valid prescription from a licensed healthcare provider is required, whether you're buying new or refurbished.

What does "certified refurbished" actually mean?

It means the machine has been previously used, then thoroughly cleaned, disinfected, and tested to confirm it's in good working condition before it's offered for sale. All of our refurbished units have less than 700 hours of usage.

Is a refurbished AirSense 11 as effective as a new one?

Yes. A certified refurbished AirSense 11 runs the exact same AutoSet algorithm and software as a brand new unit. The difference is in appearance and usage history, not therapy performance.

Will my refurbished machine have cosmetic wear?

It might. Refurbished and gently used machines may show minor cosmetic imperfections, even though they've been fully cleaned and tested. If cosmetic condition matters to you, our brand new AirSense 11 page is linked above.

What's covered under the warranty?

Every refurbished machine includes a 14 day warranty from GoCPAP.com starting on delivery, plus whatever portion of the original ResMed manufacturer's warranty remains. That remaining time will be printed and included with your machine. Contact us if you have questions about your specific unit's coverage.

Is a copy of my prescription required at checkout?

Yes, when applicable, a valid prescription is required for U.S. residents purchasing this device.

    Refurbished AirSense 11

    Posted by Hannah on May 11th 2026

    The Certified Refurbished ResMed AirSense 11 AutoSet is a great value and perfect for first time CPAP users, a backup unit, or for those paying out of pocket for a machine. It was professionally refurbished and certified by a clinical team, giving me confidence in the quality. The package also includes new accessories like the air filter, water chamber, and standard tubing, all at a very reasonable price. Great bang for your buck overall!
