There is no single replacement calendar for every CPAP part. Follow the instructions for your exact equipment, inspect it regularly and replace worn or damaged parts as directed. An insurance allowance tells you what may be covered; it does not automatically mean an intact part must be replaced that often.
What to check before replacing a part
| Part | What to check |
|---|---|
| Cushion or nasal pillows | Tears, deterioration, loss of shape or persistent leaks after correct fitting and cleaning. Follow material-specific instructions |
| Headgear and frame | Stretching, damage or inability to maintain the intended fit without overtightening |
| Tubing | Holes, tears, cracks or damaged connectors |
| Disposable filter | The exact machine's replacement interval; inspect sooner for dirt, blockage or damage. Do not wash disposable filters |
| Water chamber | Leaks, cracks, pitting or a damaged seal; follow the chamber's cleaning instructions |
| Machine | Manufacturer service-life guidance, faults and advice from your provider; do not replace it just to obtain a supply bundle |
For example, ResMed's AirSense 11 instructions say to replace the air filter at least every six months, and sooner if it is damaged or blocked by dirt or dust. That is different from insurance schedules that may allow filters more frequently. Check the AirSense 11 user guide and the manual supplied with your exact equipment.
Silicone and memory foam need different care
Do not use one cleaning routine for every cushion. Follow the mask manual for cleaning washable silicone parts. AirTouch F20 memory foam must not get wet: ResMed allows a dry cloth or an alcohol-free wipe when needed and recommends a new foam cushion each month. See the AirTouch F20 care instructions.
For tubing, headgear and chambers, follow their own washing and drying instructions. Use the water type specified for your chamber. Good care supports continued use, but it does not repair damaged parts or override a manufacturer replacement instruction.
What insurance replacement schedules mean
Medicare's PAP policy lists usual maximum quantities such as one full-face cushion per month, two disposable filters per month and one headgear every six months. Coverage also depends on medical need and the applicable refill requirements. These quantities are coverage limits, not a universal maintenance schedule or a promise of reimbursement. See the CMS PAP coverage policy and confirm your own plan's rules.
How to stay on top of replacements
- Keep a list of your machine model, mask model, cushion size and compatible parts.
- Set reminders to inspect and care for parts according to their manuals.
- Keep a useful spare if it helps you avoid being without a needed part.
- Ask your provider about persistent leaks, irritation or changes in therapy before assuming a new part is the only answer.
Keeping a spare without replacing the whole setup
Already own an AirSense or AirCurve 10 or 11? Our CPAP supply bundles bring together SlimLine or heated tubing, a matching water chamber and six filters. Choose the bundle for your machine generation and the tubing you prefer.
A spare cushion or tube can be useful when a worn part needs replacing. Start with your exact mask model, cushion size and machine generation, then choose only the parts you need from our CPAP replacement supplies.
If you are also buying a new mask, eligible product pages offer one extra matching cushion as a bundle. For a P10 FitPack with extra pillows, you choose the spare size separately because the mask already includes Small, Medium and Large. Selected new machines also offer a spare tube, chamber and filters.
The bundles are optional, one-time purchases. They do not start automatic deliveries or set a replacement schedule. Follow the care and replacement instructions for your specific equipment; silicone and memory-foam cushions need different care.
The bottom line
Use the equipment instructions, its condition and your provider's advice to decide when a part needs replacing. Shop replacement supplies by the exact model and size.
