How Often Should You Replace Your CPAP Supplies?
Most people use their CPAP supplies far too long. Here's the exact replacement schedule — and how insurance typically covers all of it.
Replacing your CPAP supplies on schedule isn't just about hygiene — it's essential for therapy to work. Worn mask cushions lose their seal. Tubing develops micro-tears. Filters clog with dust and bacteria. When your equipment degrades, your therapy degrades with it: you lose pressure, you lose comfort, and your airway doesn't stay open the way it should.
The good news: most major insurance plans cover CPAP replacement supplies on a set schedule, and millions of CPAP users never claim what they're entitled to. The result is worn-out equipment that could be replaced for free — every 90 days, every 6 months, even an entirely new machine every five years.
Below is the standard replacement schedule recognized by most private insurers, what's covered at each interval, and why each item matters.

The CPAP Replacement Schedule
This is the standard schedule recognized by most major insurance plans. Items in each category are typically covered at little or no out-of-pocket cost when you're eligible and in compliance with therapy.
* Coverage varies by plan. We verify in real time and bill insurance directly.

If you have a major insurance plan, there's a strong chance everything on this schedule is covered. Most CPAP users never claim what they're entitled to. We verify insurance and handle all the billing paperwork. You pay only what your plan requires — often nothing at all.

Your CPAP or BiLevel machine is typically covered by insurance every five years, and most patients never take advantage of it. If your machine is five or more years old, today’s models are dramatically better — auto-titrating pressure, whisper-quiet operation, integrated heated humidification, and app-based tracking — and you may be eligible for an upgrade at little or no cost through your insurance.
Covered Every 5 Years
- CPAP machine — fixed or auto-adjusting (APAP); the core of your therapy
- BiLevel / BiPAP machine — for patients who need different inhale and exhale pressures
AirSense 11 AutoSet
Best for most users. Latest tech.
AirSense 10 AutoSet
Best value. Proven reliability.
AirCurve 11 VAuto
For higher pressure needs.
If your machine is five years old or older, you may already be eligible for a covered replacement today.
Six Month Replacements
Every six months, your headgear, humidifier water chamber, and non-disposable filters are eligible for replacement. These are the structural components that degrade slowly — you may not notice the wear until you compare them to a fresh set and realize how much has changed.
Headgear stretches with daily use, losing the elasticity that holds your mask in proper position. A loose headgear means over-tightening to compensate, which causes facial marks, discomfort, and a cycle that makes you less likely to use your CPAP. Water chambers develop mineral deposits and micro-scratches that harbor bacteria. Non-disposable filters lose their filtering effectiveness, increasing your machine's workload and reducing air quality.
Covered Every 6 Months
- Headgear — the straps and frame that hold your mask in position; stretches with wear and body oils
- Water chambers — mineral buildup and micro-scratches reduce effectiveness and harbor bacteria over time
- Non-disposable filters — washable foam or ultra-fine filters that lose filtration capacity with repeated use
Many patients skip their six-month replacements because the items "look fine." But headgear stretch is gradual — once the elastic has lost its tension, you can't get it back. Replace on schedule and you'll notice the difference immediately: a tighter seal, less leakage, and more comfortable nights.
Three Month Replacements
Your mask, tubing, and mask cushions are the highest-contact parts of your CPAP system — and they degrade faster than anything else. Every three months, you're eligible for a complete mask replacement (frame and cushion), new tubing, and a fresh set of disposable filters.
Tubing becomes brittle and develops micro-tears that leak pressure. The silicone in mask cushions loses its pliability and stops conforming to your face the way it did when new. Even when you can't see the wear, the seal degrades — and a leaking mask means wasted pressure, disrupted therapy, and poor sleep.
Covered Every 3 Months
- Standard and heated tubing — 6-foot corrugated tube; becomes rigid and develops micro-tears with regular flexing
- Masks without headgear — every 3 months
- Full face cushions — every month
- Nasal cushions and nasal pillows — every 2 weeks
- Disposable filters — 2 per month (some plans allow monthly replacement as a separate benefit)
Could your new mask cost you nothing?
Most plans cover a full mask replacement every 90 days. Verify your eligibility in 60 seconds.
Routine Maintenance Between Replacements
Regular cleaning keeps bacteria at bay, maintains your seal, and extends the life of your supplies. Here's a simple routine.
Daily
- • Wipe mask cushion with damp cloth
- • Empty & air-dry humidifier chamber
- • Refill with distilled water at night
Weekly
- • Wash cushion & headgear with mild soap
- • Flush tubing with warm soapy water
- • Clean water chamber with vinegar rinse
- • Wipe down machine exterior
Monthly
- • Replace disposable filters if discolored
- • Inspect tubing for cracks or yellowing
- • Check cushion for tears or hardening
Warm water and mild dish soap is all you need. For UV sanitization without chemicals, the Lumin CPAP Cleaner is a popular option.
