We’re all looking for ways to save money but when it comes to your health, remember there is a price to pay if you try to cut corners. While buying a used machine may save you money upfront, there is a significant cost to compromising the quality and efficacy of your CPAP therapy. Here’s what to consider when deciding between purchasing a used or new CPAP machine.

Dangers of Using Someone Else’s CPAP Machine

When you purchase a used CPAP machine, little is known of the previous user. You are unfamiliar with their own medical history and daily care regimens. Even a thorough cleaning and sanitizing after purchase cannot completely eliminate previous contamination. CPAP machines create a warm, sometimes moist environment, making them ideal breeding grounds for yeast, mold, bacteria and mildew—especially if the previous owner did not properly take care of the machine. 

There is also a lot unknown about the previous owner’s lifestyle. For example, did the owner have pets that could have come in contact with the equipment? Did they live in a part of the country that was humid, high altitude, or closer to the desert that might impact the way the machine works? 

Lastly, if you do not purchase a new machine, your device is not covered by a manufacturer’s warranty. If the device fails to work efficiently, it could be a costly mistake!

Keep Sanitation a Priority

Every CPAP machine requires maintaining a manufacturer-recommended strict cleaning and replacement regimen. Following these requirements is essential for the effective use and long-term maintenance of your machine. Failure to follow proper cleaning protocols can result in germs entering your CPAP machine and can lead to sinus and respiratory infections, pneumonia, bronchitis and other illnesses from bacteria and viruses. With used CPAP machines where the history of cleaning is unclear, the risk of infection is significantly higher. 

Should I Purchase a Used CPAP Machine?

The health risks of buying a used CPAP machine alone outweighs the savings. However, keep in mind that the FDA considers CPAP machines Class II medical devices, which means that they cannot be sold or purchased without a medical prescription. 

Avoid CPAP machines you find in garage sales or on Craigslist. Avoid online companies selling “gently used” CPAP machines. Also, do not take a used CPAP machine from a friend, even if it’s free.

Benefits of a New CPAP Machine Compared to a Used CPAP Machine 

Besides having the peace of mind that a clean, brand new CPAP machine is all yours and has never been shared with another person, there are other benefits over buying a used CPAP machine. 

  • Your new machine should fit your exact CPAP prescription needs, while an old machine may not. Each machine that is purchased at The CPAP Shop is calibrated to fit your needs based on your physician’s recommendations.
  • You can more easily get replacement parts for new CPAP machines, compared to old out-of-date used machines. 
  • Newer machines work more efficiently and are designed to have fewer parts for a longer lifecycle.
  • You receive the full warranty on a new machine. Old machines may have expired warranty protection. If your machine doesn’t work well after purchase, you will not be covered for any repair or replacement and will need to buy a new machine anyway.
  • New CPAP machines can last up to five years. A used machine may be nearing the end of its life by the time you purchase. 

Don’t Purchase a Used CPAP Machine if You Can Afford a New CPAP

Because using a new CPAP machine is so important for your health, The CPAP Shop does not sell used or refurbished CPAP equipment and recommends that you only purchase from a supplier that guarantees the same quality of products. You want to be sure the products you purchase come directly from the manufacturer.
