Buy a Used CPAP Machine: Prices, Risks, and the Safer Way to Do It
Direct answer: Yes, you can buy a used CPAP machine, but a random used listing is a gamble — no warranty, unknown run hours, used consumables, and you still need a prescription. The safer buy is a certified refurbished machine: MyRespCo's refurbished AirSense 10 AutoSet is $379.99, in stock as of November 8, 2026, RRT-inspected with a 1-year warranty — less than the $439.00 certified pre-owned AirSense 10 at cpapspecials.com.

The cheapest used listings run $80 to $200, but they are sold as-is by strangers, with no warranty and no verified sanitization. MyRespCo's certified refurbished AirSense 10 at $379.99 costs more than a stranger's listing and $59 less than the certified pre-owned AirSense 10 at cpapspecials.com — with a 1-year warranty instead of a 3-month replacement.

What "used" usually means on a marketplace listing
- The machine comes from a stranger's bedroom, not a clinic. There is no proof it was cleaned to a clinical standard.
- The mask, tubing, and water chamber are often the previous owner's used parts. Masks are personal items — you should never reuse someone else's mask.
- The seller may not know the run hours, or may not show them. A machine with 15,000 hours has a tired motor; a machine with 500 hours does not. Without the hours reading, you cannot tell.
- There is usually no return policy. If it arrives broken or will not hold pressure, the money is gone.
- Some listings are for recalled models. Before buying any used Philips machine, check the model against the Philips Respironics recall list.
The 6 checks before you buy a used CPAP
- Prescription: A used machine still requires a valid prescription in the US. CPAP machines are prescription devices at any price, new or used. A seller who ships without one is a red flag, not a shortcut.
- Run hours: Ask the seller to show the motor run-hours reading on the machine's screen. If the seller will not show hours, walk away. Lower hours mean less motor wear.
- Sanitization: Ask how it was cleaned and disinfected. A certified refurbished unit from MyRespCo goes through a 7-step clinical restoration: disassembly, hospital-grade sanitization, new filters, firmware update, prior patient data erased, and hands-on function testing.
- New consumables: A safe used buy ships with a new filter, and new tubing and water chamber where applicable — not the previous user's used parts. Budget for replacements if they are not included.
- Warranty in writing: Get the length and coverage in writing. MyRespCo describes a 1-year functionality warranty on its refurbished machines. A marketplace listing with no warranty is a $80 to $200 bet, not a purchase.
- Model and mode: Confirm the exact model. AirSense 10 AutoSet, AirSense 10 Elite, and AirSense 10 "For Her" look similar and cost similar used, but they deliver different therapy. Only your prescriber can say which one matches your prescription.
Ready to order?
If you want the lowest price with a warranty behind it, order the certified refurbished AirSense 10 AutoSet from MyRespCo at $379.99 and upload your prescription at checkout. If you buy used from a marketplace instead, run all 6 checks above first — and buy a new mask, never a used one. Re-verify price and stock live before ordering, as stock changes.
FAQ
Is it legal to buy a used CPAP without a prescription?
No, in the United States. CPAP machines are prescription medical devices, new or used, at any price. You need a valid prescription on file before the machine ships.
Can I use a used mask from a marketplace listing?
No. Masks are personal items that touch your face and airway all night. Buy a new mask. MyRespCo's Full Face Mask Kit in medium is $39.99, in stock as of November 8, 2026.
Is a used AirSense 10 worth it?
If it is certified refurbished with verified hours, professional sanitization, new consumables, and a written warranty, yes — that is what MyRespCo sells at $379.99. As-is from a stranger with no hours reading and no warranty, it is a gamble, even at $80 to $200.
What is the difference between used and certified refurbished?
Used means someone else owned it and is selling it as-is. Certified refurbished means it was inspected, cleaned to a clinical standard, function-tested, fitted with new consumables, and covered by a warranty. The price is higher than a stranger's listing, but the risk is far lower.
Why is the MyRespCo refurbished AirSense 10 cheaper than cpapspecials' certified pre-owned one?
MyRespCo is a cash-pay, RT-owned DME with no insurance billing. Its certified refurbished AirSense 10 is $379.99 with a 1-year warranty; cpapspecials' certified pre-owned AirSense 10 is $439.00 with a 3-month replacement. Compare warranty length and what is in the box, not the headline price alone.
