If you have been prescribed a continuous positive airway pressure (CPAP) machine to treat your sleep apnea, you might be curious about how long the machine will last.
Below, we’ll cover the typical lifespan of CPAP machines, signs it might be time to replace your CPAP equipment, how to maintain your CPAP, and what types of replacements insurance is likely to cover.
Average CPAP Machine Lifespan
Most continuous positive airway pressure (CPAP) machines last approximately 5 years. The lifespan of a CPAP machine can vary depending on the make and model, how often it’s used, the pressures delivered, and whether it’s properly maintained. Some models may only last 3 or 4 years, while others have often been known to last longer than 10 or even 20 years.
How long a CPAP device lasts depends largely on its materials and design. Cleaning and replacing components as needed can help extend its longevity. Though heavy use may shorten the lifespan, it’s still important to use the device nightly as prescribed by your doctor.
Most CPAP machines age gradually, but some models experience a sharper drop in functionality around the 3- to 5-year mark. More rarely, a CPAP device may be recalled by the manufacturer due to a safety or performance issue.

Signs Your CPAP Machine Needs to Be Replaced
Keep your eyes peeled for any of the following as indications that it’s time to buy a new CPAP machine:
Your Machine Is Noisy
All CPAP machines make a consistent whirring sound that’s usually easy to ignore. If you notice your machine making new sounds, especially while inhaling, it may be a sign it needs to be replaced. Before a full machine replacement, it’s a good idea to get a new mask and/or tubing in case either of those components is worn out and not the machine itself.
Your Machine Is Losing Pressure
A worn-out machine may not be able to deliver air pressure at the correct rate. If you have used your CPAP machine for a while, you’ll likely notice the difference if the airflow changes. First, check to make sure your mask is fitting correctly, and then look into replacing your CPAP machine.
The Machine Will Not Turn On
Your CPAP machine not turning on or staying on is a sure sign that something is broken. You may also notice that the digital display isn’t visible or working correctly. Reach out to the durable medical equipment provider to check if it’s necessary to replace the power supply. If not, you’ll need a new machine.
You See Damage
Cracks and other damage may indicate that you need a new machine, but it’s also possible to replace individual parts. Humidifier water chambers usually need to be replaced every 6 months, and some manufacturers are able to replace power cords.
The Humidity Level Changes
If the air from your CPAP feels dryer than usual or if the water level in your humidifier’s water chamber isn’t going down as quickly as it normally does, it may be time to replace your humidifier. Before buying a new one, first check that the heating element is working and that the heat settings are correct.
Your Symptoms Return
If any of your sleep apnea symptoms return, it’s a good indication that your machine is not working properly. You or your sleep partner may notice snoring, or you may simply begin to feel less rested. Check with your doctor to see if your machine is calibrated correctly or if it’s time to invest in a new machine.
Your Machine Is Overheating
Overheating is usually because of a malfunction and not normal, even for an aging machine. If your machine feels overly hot to the touch, and especially if it’s smoking, you should unplug it immediately. Reach out to the durable medical equipment provider to see about getting a replacement, and consider reporting the issue to the U.S. Food and Drug Administration (FDA).
You Get a Warning From Your Machine
Some CPAP machines display warnings when they detect that a major component is wearing out or the device has reached the end of its expected service life. Messages such as “motor life exceeded,” “service required,” or repeated hardware-related errors may indicate that the machine needs professional evaluation or replacement.
Check the manufacturer’s guidance for the specific message, especially if it returns after restarting the device or basic troubleshooting.
How to Make Your CPAP Machine Last Longer
Regularly cleaning your CPAP machine, replacing parts as needed, and familiarizing yourself with the warranty terms can help reduce the chances of premature damage.
Clean on a Schedule
Cleaning your CPAP machine’s components helps keep out allergens and bacteria, and prevents unnecessary strain on the device from dust and dirt.
Check your user manual for instructions on how to clean your CPAP machine. Different components may need to be cleaned on a daily or weekly basis. Most manufacturers recommend using warm water and mild soap to clean CPAP masks, tubing, and humidifier water chambers.
Avoid using ultraviolet light and ozone cleaners, as the FDA has issued a warning about their safety and efficacy. These cleaners will void the manufacturer’s warranty of the device.
Replace Parts Regularly
To keep the machine working properly, replace the filter, mask components, tubing, headgear, and the humidifier water chamber on a regular basis according to the manufacturer’s instructions.
| Item | Replace Every |
| Nasal pillows | 2 weeks |
| Nasal or full-face mask cushion | 1 month |
| Mask frame | 3 months |
| House and tubing | 3 months |
| Headgear | 6 months |
| Chin strap | 6 months |
| CPAP machine filters | 2 to 4 weeks month (disposable), 6 months (reusable) |
| Humidifier water chamber | 6 months |
| Heated humidifier | 5 years |
| CPAP machine | 5 years |
Know Your Warranty
Most CPAP warranties cover material and workmanship defects during the first 2 years after purchase in the United States. Read the warranty terms and follow the cleaning, usage, and maintenance instructions to remain eligible for coverage. If an issue comes up, submit a claim as soon as possible.
Insurance Coverage for Replacement CPAP Machines
Most insurance — including private insurance, Medicare, and Medicaid — will cover the replacement of a CPAP machine. It’s a good idea to check your specific plan for any requirements or timelines, but insurance will generally cover replacement if a machine is lost, damaged beyond repair, or has reached the end of its useful life.
How Often Does Medicare Cover a New CPAP Machine?
Medicare generally considers a CPAP machine to have a 5-year reasonable useful lifetime. After 5 years, Medicare may cover a replacement if you still use and benefit from CPAP therapy. Different requirements apply depending on why the machine is being replaced and whether Medicare originally covered it.
- If Medicare covered your CPAP and it's lost, stolen, or irreparably damaged before 5 years: Medicare may cover a replacement without requiring a new medical evaluation, sleep study, or trial period, as long as the loss or damage resulted from a specific incident.
- If Medicare covered your CPAP and it's at least 5 years old: You don't need another sleep study or another CPAP trial period. However, your treating practitioner must evaluate you in person and document that you continue to use and benefit from PAP therapy.
- If you received your CPAP before enrolling in Medicare: Medicare may cover the device, a replacement, or related supplies if your previous sleep study meets Medicare's eligibility criteria and you have an in-person evaluation after enrolling in Medicare that documents your OSA diagnosis and continued CPAP use. A new sleep study may be needed if your previous testing doesn't meet Medicare's requirements.
Medicare may require repeat sleep testing in certain other situations, such as requalifying after an unsuccessful initial CPAP trial or evaluating therapy after a major weight change or return of symptoms. Coverage requirements under Medicare Advantage, Medicaid, and private insurance plans may differ.
Can You Use an FSA or HSA to Replace Your CPAP Machine?
Flexible spending accounts (FSA) and health savings accounts (HSA) are designed to help cover medical expenses and should be eligible for use toward replacing a CPAP machine. Before allocating funds to replace a CPAP device, confirm eligibility with your FSA or HSA plan provider.
Frequently Asked Questions
Can you use an old CPAP machine as a backup?
If your old CPAP machine has been well maintained and is still in good working condition, then it may be acceptable to use as a backup. You should not use a machine with broken parts or a device that is not properly calibrated, as these do not provide effective treatment for sleep apnea.
Do CPAP machines get less effective over time?
CPAP machines are designed to work well until they are ready for replacement. There may be a slight dip in performance over time, but when they become noticeably less effective, you should replace faulty parts or get a new machine.
What can you do with your used CPAP machine?
Certain charitable organizations and medical equipment companies accept donations of used CPAP machines, providing they meet certain criteria. You may also be able to sell to an authorized reseller or dispose of a used CPAP machine at local recycling facilities.
