A CPAP machine is the most widely used treatment for obstructive sleep apnea, and for many people it changes everything: deeper sleep, fewer morning headaches, more energy and a lower strain on the heart. The pricing, however, is confusing. You will see machines advertised for a few hundred dollars, insurance statements showing monthly rental charges, and a constant stream of replacement supplies. This guide explains what a CPAP machine really costs in 2026, how Medicare and private insurance pay for it, and the rules you must follow to keep your coverage.
- A CPAP or auto-CPAP machine typically costs about $500 to $1,000 or more at retail, before masks and supplies.
- Medicare Part B covers CPAP as durable medical equipment after a sleep study confirms obstructive sleep apnea, starting with a 3-month trial.
- To keep coverage, you generally need to use CPAP at least 4 hours a night on 70% of nights during a 30-day period in the trial.
- Medicare rents the machine for 13 months (you pay 20% after the deductible), then you own it.
How much does a CPAP machine cost?
| Item | Typical retail cost | How often it is replaced |
|---|---|---|
| CPAP or auto-CPAP (APAP) machine | About $500 to $1,000+ | About every 5 years |
| Mask (nasal, pillows or full face) | Often $50 to $200 | About every 3 months (frame), cushions more often |
| Tubing | Often $15 to $40 | About every 3 months |
| Disposable filters | A few dollars each | Monthly or more often |
| Humidifier water chamber | Often $20 to $60 | About every 6 months |
| Headgear | Often $20 to $50 | About every 6 months |
Replacement intervals reflect the schedules Medicare generally follows, summarized by the National Council on Aging. Prices are typical retail ranges and vary by brand.
Over five years, supplies can add up to more than the machine itself if you pay out of pocket, which is why understanding coverage matters.
CPAP vs. auto-CPAP vs. BiPAP
- CPAP delivers one fixed air pressure all night, set by your doctor.
- Auto-CPAP (APAP) adjusts pressure breath by breath within a range. Many doctors now prescribe it by default because it adapts to sleep position, alcohol, weight changes and congestion.
- BiPAP uses a higher pressure for breathing in and a lower one for breathing out. It costs more and is usually reserved for people who cannot tolerate CPAP or have other breathing conditions.
How Medicare covers CPAP
Medicare Part B covers CPAP machines and supplies as durable medical equipment (DME) when you have been diagnosed with obstructive sleep apnea through a sleep study. If you are not yet diagnosed, our guide to sleep apnea signs and treatment explains the symptoms that should prompt testing.
Step 1: The 3-month trial
Medicare first covers CPAP for a 12-week trial. During this period your machine records how many hours you use it each night, and many devices send that data wirelessly to your supplier.
Step 2: Prove that it is working
Between roughly day 31 and day 91 of the trial, you need an in-person or telehealth visit with your treating provider. They document that CPAP is helping your symptoms and that you meet the adherence standard: at least 4 hours per night on 70% of nights during a consecutive 30-day period. If you do not meet it, Medicare can stop paying, and you may need to repeat the trial or testing.
Step 3: 13 months of rental, then you own it
Medicare pays the supplier a monthly rental for 13 months. You pay 20% of the Medicare-approved amount after meeting the Part B deductible ($283 in 2026). After 13 continuous months of rental, the machine is yours. Medicare generally covers a replacement machine after its useful lifetime, typically five years.
Step 4: Supplies on a schedule
Masks, cushions, tubing, filters and water chambers are covered at set intervals, with 20% coinsurance. Your supplier must be enrolled in Medicare. Choosing one that accepts assignment keeps your share limited to the 20% coinsurance.
A Medigap policy can cover that 20%. Medicare Advantage plans must cover CPAP too, but they may require prior authorization and in-network suppliers, and their cost-sharing differs.
Private insurance coverage
Most private insurers follow a similar model: a diagnostic sleep study, a rental or rent-to-own period and adherence requirements. Some plans apply CPAP costs to your deductible, meaning you may pay the full rental until you meet it. Ask your insurer three questions: Is prior authorization required? Is the machine rented or purchased? What is the replacement schedule for supplies?
Ways to save on CPAP if you pay out of pocket
- Get the prescription in hand. In the U.S., CPAP machines require a prescription, even from online retailers.
- Compare retail prices online. Cash prices from online suppliers can be lower than billed insurance rates, especially if you have a high deductible.
- Use HSA or FSA funds. CPAP machines and supplies are eligible medical expenses.
- Ask about refurbished machines from reputable suppliers that offer a warranty.
- Replace only what is worn. Follow your provider’s advice, but a clean, intact mask frame may last longer than the maximum allowed interval.
- Check manufacturer and nonprofit programs for people with limited income.
Tips to make CPAP easier to use
Insurance coverage depends on using the machine, and so do the health benefits. Common complaints have fixes:
- Mask discomfort or leaks: try a different style or size. Nasal pillows suit many people who feel claustrophobic.
- Dry mouth or nose: use heated humidification or a heated tube, or switch to a full face mask if you breathe through your mouth.
- Pressure feels too strong: ask about the ramp feature or auto-CPAP.
- Can’t fall asleep with it: practice wearing the mask while reading or watching TV before bed.
- Noise: modern machines are quiet; a leaking mask is the usual culprit.
If you cannot tolerate CPAP despite these adjustments, talk to your sleep doctor. Alternatives include oral appliances and, for some people, an implanted nerve stimulator.
Why sticking with CPAP is worth it
Untreated sleep apnea is linked to high blood pressure, heart disease, stroke, type 2 diabetes, daytime sleepiness and car crashes. Using CPAP consistently reduces breathing interruptions immediately, and many people feel more alert within days or weeks. Poor sleep also affects mood; if anxiety or low mood are part of the picture, our guide to online therapy costs covers affordable support options. And because Medicare coverage rules differ by device, our comparison of OTC vs. prescription hearing aids is a helpful example of equipment that Medicare does not cover.
Cleaning and caring for your CPAP
- Wipe the mask cushion daily with a damp cloth or mask wipe.
- Wash the mask, tubing and water chamber weekly in warm, soapy water and let them air dry.
- Use distilled water in the humidifier to reduce mineral buildup.
- Check filters regularly and replace them when discolored.
The FDA has warned against CPAP cleaning devices that use ozone or ultraviolet light, which are not cleared for that purpose. Soap and water work well.
Talk to a doctor if you snore loudly, someone has seen you stop breathing during sleep, or you wake up gasping, have morning headaches or are very sleepy during the day. If you already use CPAP, contact your sleep provider if symptoms return, you gain or lose significant weight, the mask causes sores, or you cannot reach the nightly usage goal. Seek urgent care for chest pain, severe shortness of breath or falling asleep while driving.
