Should You Buy a Used CPAP Machine?

Key Takeaways

• Buying a used CPAP machine can be a cost-effective option if it’s purchased from an authorized reseller, but buying one from informal sellers carries significant safety risks.
• Even with a used machine, you still need a valid prescription and should follow the same process that applies when buying a new device.
• Insurance coverage and reimbursements for used CPAP machines vary significantly; coverage is more likely if the machine comes from an authorized refurbisher.

Are Used CPAP Machines Safe?

Using a refurbished CPAP machine is relatively safe if it's been properly maintained and thoroughly cleaned. However, you should always use your own new, unused CPAP accessories, such as the mask and filters. 

Benefits of Buying a Refurbished CPAP Machine

A refurbished CPAP machine can be a cost-effective alternative to buying new, but only when it comes from a reputable, authorized reseller. These devices are professionally inspected, cleaned, and tested to ensure they meet safety and performance standards, offering greater reliability than purchasing a used machine from an informal seller or online marketplace. 

Refurbished machines often include a limited warranty, verified usage hours, and replacement parts like new tubing or filters, helping users save money without sacrificing quality.

Risks of Buying a Used CPAP Machines

It’s difficult to fully sanitize the internal parts of a CPAP machine, which may have accrued mineral buildup, pathogens, mold, allergens, or other potentially harmful contaminants during its time with the previous owner.

Another risk of buying a pre-owned machine is that it may have defects or missing parts. For these reasons, you should only purchase used CPAP machines from authorized resellers.

Is a Used CPAP Machine Right For Me? 

While Dr. Breus generally recommends buying a new CPAP machine, a used device may be an option for shoppers on a budget or those who don’t have health insurance.

What’s the Best Way to Buy a Used CPAP Machine?

Although it’s more common to buy a new CPAP machine, there is still a way to buy a used or refurbished CPAP machine.

Sleep Apnea Diagnosis and CPAP Prescription

Just as you would when purchasing a new device, you need a prescription to be able to purchase a used CPAP machine. Never buy a CPAP device from a seller who doesn’t ask you for your prescription.

If you haven’t been diagnosed yet, you’ll need to complete a sleep study—either in a sleep lab or using an at-home test—before a sleep specialist can write your prescription. Sleep Doctor offers a home sleep test that provides a fast, convenient way to get diagnosed and receive a prescription without visiting a sleep lab.

Places to Buy a Used CPAP Machine

Authorized resellers online and in physical stores sell CPAP machines that have been professionally refurbished for use by a new owner. Buying online offers more choices and often better prices, but buying from a brick-and-mortar store allows you to inspect the device before purchasing. Certain programs also connect people in need with gently used CPAP equipment.

Avoid Unauthorized Third-Party Sellers

You may come across advertisements for second-hand CPAP machines on third-party sites like Craigslist, but you shouldn’t buy a used CPAP machine through these channels. Class II devices, including CPAP machines, must meet a set of stringent health and safety criteria set by the U.S. Food and Drug Administration (FDA), and purchasing from an authorized provider helps ensure that your used machine meets these criteria.

Insurance Coverage for a Used CPAP Machine

Whether or not a used CPAP machine will be covered by insurance will depend on your specific provider and plan. Check your policy details or contact your insurance provider to see if your plan covers refurbished or used equipment. 

Retailers that sell refurbished CPAP machines often don’t partner directly with Medicare or private insurance companies. However, they may provide the codes and paperwork necessary for you to submit a claim for out-of-network reimbursement from your insurance company. You may need to prove that CPAP therapy is helping you and demonstrate regular use to qualify for coverage.

Using an FSA or HSA for a Used CPAP Machine

Flexible spending accounts and health savings accounts are designed to cover the cost of health care expenses, including medical equipment. These plans should cover the cost of a used CPAP device from authorized resellers, although it’s important to confirm the necessary process with both your plan provider and the CPAP machine reseller before purchasing.

Frequently Asked Questions

Can you use someone else's CPAP machine?

No, you should not use someone else’s CPAP machine. CPAP devices are prescription medical equipment that must be set to your specific pressure needs based on your sleep apnea diagnosis. Using another person’s machine can expose you to incorrect pressure levels, poor treatment, hygiene risks, and potential device contamination.
