Every year, millions of Americans are diagnosed with sleep apnea and prescribed CPAP therapy. A significant portion either don't tolerate CPAP, move to a different treatment (like oral appliances or surgery), or upgrade to a newer machine when their insurance renews. The result: millions of perfectly functional CPAP and BiPAP machines sitting in closets.
Here's the good news — that equipment has real resale value. Here's everything you need to know about selling your CPAP in 2026.
Is It Legal to Sell a Used CPAP Machine?
Yes — with an important distinction. In the United States, CPAP machines are classified as Class II medical devices. You can legally sell your own used CPAP machine as a private individual. What you cannot do is sell CPAP equipment commercially without proper FDA registration and licensing (i.e., you can't start a storefront selling used CPAPs without a medical device dealer license).
Private resale of your own equipment? Completely legal. People do it on eBay, Craigslist, and through specialty medical equipment buyers like StripValue every day.
What Is My CPAP Machine Worth? (2026 Prices)
CPAP resale values vary significantly by brand, model, and age. ResMed and Philips Respironics dominate the market, and newer AutoCPAP (APAP) models fetch substantially more than older fixed-pressure units.
| CPAP Machine | Resale Value (Good Condition) | Notes |
|---|---|---|
| ResMed AirSense 11 AutoSet | $180–$260 | Top value — most popular APAP in 2024–25 |
| ResMed AirSense 10 AutoSet | $120–$180 | Still in high demand |
| ResMed AirSense 10 Elite (fixed) | $80–$130 | Fixed pressure, lower demand |
| ResMed AirCurve 10 VAuto (BiPAP) | $200–$320 | BiPAP commands premium |
| ResMed AirMini (travel) | $150–$220 | Travel size = popular |
| Philips DreamStation 2 Auto | $80–$140 | Lower due to recall concerns |
| Philips DreamStation (original) | $30–$70 | Recall-affected — very low value |
| Fisher & Paykel SleepStyle | $90–$150 | Less common but decent value |
| Luna G3 / 3B Medical | $70–$110 | Budget tier |
*Values are for machines in good working condition with power supply. Humidifier chambers and masks are additional but often not worth much separately.
The Philips Recall Problem
In 2021, Philips issued a massive recall for DreamStation and System One machines due to a foam degradation issue. If your machine is a Philips DreamStation (first-generation), it's part of the recall. You may still be eligible for a replacement unit from Philips — check the recall status at philipsrecallregistration.com before selling, because getting a free replacement is worth more than the $40–$70 you'd get selling a recalled unit.
The newer DreamStation 2 was not subject to the original recall, but consumer confidence in the brand has taken a hit, which is reflected in lower resale values compared to equivalent ResMed models.
What to Include When Selling
- The machine itself (obviously)
- Power supply / cord — significantly reduces value if missing
- Humidifier chamber — can add $20–$40 if included
- Original box — helpful but not required
- Heated tubing — adds value if compatible and in good shape
Masks, filters, and used cushions have essentially no resale value (disposables). Don't worry about including them.
💡 Before selling: Reset your CPAP to factory settings to remove your personal sleep data. For ResMed: Settings → My Options → Reset. For Philips: check your manual or call 1-800-345-6443.
Where to Sell a CPAP Machine
eBay: The largest market for used CPAP equipment. You can get top dollar but have to deal with listing, shipping, and buyer disputes. Factor in 12–15% eBay/PayPal fees.
Facebook Marketplace: Good for local sale, no fees. But CPAP buyers on FB are often very price-sensitive and knowledgeable — expect low-ball offers.
Specialty buyers (like StripValue): Fast, easy, no hassle. You get less than a perfect eBay sale, but you also don't have to deal with listing, packaging, or difficult buyers. Best option if you want cash quickly without effort.
Local medical equipment consignment: Some medical supply stores buy used CPAPs. Call ahead — most don't.
How Much is My CPAP Mask Worth?
Almost nothing, unfortunately. Used masks have direct skin contact, and buyers are rightfully cautious. A lightly-used full-face or nasal mask might sell for $10–$25 on eBay with good photos and a clear description of its condition — but it's rarely worth the effort. Focus on the machine itself.
