Using CPAP
CPAP Supply Replacement Schedule: Masks, Cushions, Filters and Tubing
CPAP parts wear out, and worn parts are a common cause of leaks, noise and poor sleep. Insurers cover replacements on a schedule. Here is the typical timetable and the signs that something needs replacing sooner.
Why replace parts at all
Silicone cushions and nasal pillows soften and lose their seal. Headgear stretches. Tubing develops small cracks and can harbour buildup. Filters fill with dust. Replacing parts on schedule keeps leak low, keeps air clean and saves you from overtightening a tired mask.
Typical schedule
The schedule below reflects the replacement allowances commonly used by Medicare and many other insurers. Your plan and your manufacturer may differ.
- Nasal pillows or nasal cushions: up to twice a month
- Full face mask cushion: once a month
- Nasal or full face mask frame: every 3 months
- Tubing (standard or heated): every 3 months
- Disposable filters: up to twice a month
- Reusable filters: every 6 months
- Headgear and chin strap: every 6 months
- Humidifier water chamber: every 6 months
- CPAP machine: typically eligible for replacement after 5 years
Signs a part needs replacing early
- The cushion leaks even after cleaning and refitting.
- Visible tears, cracks or discolouration in the cushion, tubing or chamber.
- Headgear no longer holds its shape, and you have to tighten it more than before.
- Filters look grey or dirty.
- The chamber has cloudy marks that will not clean off.
- A new noise or whistle from the mask or hose.
Making parts last between replacements
Daily and weekly cleaning with mild soap and water extends the life of cushions and tubing, while harsh cleaners, alcohol and very hot water shorten it. Let parts dry fully out of direct sunlight, avoid stretching headgear when you take the mask off (many masks have quick-release clips for this), and store the mask somewhere it will not be crushed. Even with good care, silicone and fabric wear out, so treat the schedule as a guide rather than a challenge.
Working with insurance and your DME
Insurers cover supplies when you are using your machine and have a current prescription. Many DMEs offer automatic reorder reminders. Being covered for a replacement does not mean you must order it, but do not skip replacements to save money if the parts are failing, since leaks can undermine your treatment.
Frequently asked questions
How often should I replace my CPAP mask?
Commonly, the mask frame every 3 months and the cushion or pillows every 2 to 4 weeks depending on type. Check your insurer's schedule and replace sooner if worn.
How long does a CPAP machine last?
Many insurers, including Medicare, consider a machine eligible for replacement after about 5 years. Many machines keep working longer, but older ones may lack newer features.
Can I reuse disposable filters?
They are designed to be thrown away, not washed. Replace them when dirty or on schedule.
