Select the CPAP supplies you use and enter the last date you changed each one to see when each item is next due for replacement, based on common Medicare-aligned intervals.
About the CPAP supply replacement calendar
The CPAP supply replacement calendar helps you see, for the supplies you actually use, when each one is next due for replacement. Pick from common CPAP supplies such as the mask cushion or nasal pillows, the full-face cushion, the mask frame, headgear, a chinstrap, tubing, disposable and reusable filters, the humidifier water chamber, and the full mask. Enter the last date you changed each one, and the tool returns a copyable schedule: the common replacement interval, the next due date, and whether each item is due now, due soon, or on track.
This is an educational estimate based on common Medicare-aligned CPAP supply replacement intervals, not medical, insurance, or durable medical equipment ordering advice. Replacement intervals vary by plan, supplier, and clinician, so confirm your own schedule with your plan, your supplier, or your clinician. The tool runs entirely in your browser. It stores no prescriptions, insurer IDs, doctor names, medical records, equipment order data, or contact details, and the dates you enter are used only to compute local replacement dates and are never sent anywhere.
How to use
- Select the CPAP supplies you use from the supply list. Pick as many as apply.
- For each selected supply, enter the last date you changed or replaced it.
- Read the schedule: each row shows the common replacement interval, the next due date, and a due-now, due-soon, or on-track status.
- Use Copy schedule to copy the full list, then verify the dates with your plan, supplier, or clinician.
- Re-check the schedule whenever you change a supply so the next due date stays current.
Worked examples
Tubing: replace about every 3 months
Standard or heated tubing is commonly replaced about every three months. If you changed it three or more months ago, the schedule flags it as due now.
Nasal cushion: replace about every 2 weeks
Nasal or nasal-pillow cushions are commonly replaced about every two weeks, so they come due far more often than the mask frame or humidifier chamber.
Humidifier chamber: replace about every 6 months
The humidifier water chamber and the reusable filter are commonly replaced about every six months, so they usually show as on track between changes.
Frequently asked questions
- How often should CPAP supplies be replaced?
- Common Medicare-aligned intervals are roughly: nasal or nasal-pillow cushions about every two weeks, full-face cushions about monthly, mask frame, tubing, and full mask about every three months, and headgear, chinstrap, reusable filter, and humidifier chamber about every six months. Disposable filters are commonly changed about every two weeks. Your own schedule can differ by plan, supplier, and clinician.
- Where do these intervals come from?
- They reflect the common Medicare-aligned CPAP supply replacement schedule. This tool links to the Medicare CPAP and durable medical equipment coverage pages as the source and shows the date the intervals were last reviewed. Always confirm your own intervals with your plan, supplier, or clinician.
- Is this medical or insurance advice?
- No. This is a free educational estimate of common supply replacement timing. It is not medical, insurance, or durable medical equipment ordering advice, it does not handle prescriptions or insurer routing, and it does not place orders. Confirm your schedule and coverage with your plan, supplier, or clinician.
- What does due now, due soon, or on track mean?
- Due now means the next due date is on or before today based on the common interval. Due soon means the next due date is within the next two weeks. On track means the next due date is more than two weeks out. The status is only a reminder; your supplier or plan may use different timing.
- Does it store anything I enter?
- No. The calculator runs entirely in your browser. The supplies you pick and the last-changed dates you enter are used only to compute local next-due dates. Nothing is stored or sent to a server, and no prescriptions, insurer IDs, doctor names, medical records, or contact details are collected.
- Does it cover every CPAP supply?
- It covers the most common supplies on the standard replacement schedule. Some setups have additional or specialty parts with their own intervals. Use the closest match and confirm anything unusual with your supplier or clinician.
