What counts as CPAP supplies
A CPAP machine is the pump and pressure unit you buy once. The supplies are the parts that touch your face, seal against your airway and wear out. The usual list:
- Mask and cushions. The mask sits over your nose, or over nose and mouth; cushions or pillows are the soft seals that meet your face. These shape your nightly comfort more than anything else on the list.
- Tubing. The flexible hose from machine to mask. Heated tubing keeps the air at a steady warmth and reduces condensation, sometimes called rainout.
- Filters. The machine draws room air through a filter daily. Clean it, and replace it when it stops coming clean.
- Headgear and straps. elastic and clips that hold the mask in place, which stretch and lose grip over time.
- Humidifier chamber. The water tub in machines with humidification, which may need periodic replacement.
Each part wears at a different rate, and what feels fine one month can leak badly the next.
Typical replacement rhythms
Suppliers and clinicians commonly point to these intervals — treat them as typical guidance rather than rules, and let your own mask fit be the judge:
- Cushions and pillow seals: replace often, as the sealing surfaces change with constant use.
- Headgear: replace every few months, or whenever straps stop holding tension.
- Masks (the frame): around a similar rhythm to headgear, depending on use.
- Tubing and humidifier chambers: roughly a half-year to yearly rhythm.
- Filters: check monthly; wash weekly where reusable, replace disposables on the supplier's guidance.
The practical check is simpler than any schedule: if your mask leaks more at night, your machine ramps up, or you wake to a dry or congested nose, order the next size or a fresh set.

Where to buy, and the fitting problem
In Australia you can buy CPAP equipment from clinics, dedicated CPAP suppliers and online retailers. The machine side is usually organised with your specialist or a provider who set your therapy up. Supplies are different in one important way: fit.
A mask is not a one-size item. Seal quality depends on your face shape, whether you breathe through your nose or mouth at night, side sleeping and facial hair. A cushion that is too small leaks at the nostril margins; one that is too large presses and marks your skin. To buy in person, being measured properly by an experienced supplier beats taking a guess from a catalogue photo. Ask whether the supplier allows a fitting, a trial period, or an exchange if the first mask does not seal.
Questions worth asking a supplier
When you compare clinics and suppliers, ask:
- Do you stock my mask type and size on the shelf, not by order?
- Can I trial or exchange the mask if it leaks in the first weeks?
- Do you offer mask-fit appointments after hours for working patients?
- Will you help me contact my fund about any contributions, and supply the paperwork they need?
- How do I reach you if the seal fails and I need advice mid-therapy?
Keeping the therapy going
Supply problems are one of the most common reasons people quietly abandon CPAP. A mask that stops sealing means poor therapy, worse sleep, and less confidence in the machine — so treat replacements as part of treatment, not a shopping errand. Our overview of what CPAP is is useful if someone new to the household wants to understand why the equipment matters.

Frequently Asked Questions
How often should I replace my CPAP mask?
There is no fixed rule, but seal cushions wear earlier than the frame. Replace cushions when leaks increase or marks appear on your face, and the whole mask every few months in typical use. Your own mask fit is the honest test, so judge on performance rather than the calendar.
Can I buy CPAP supplies without a prescription?
In Australia, masks, cushions, tubing and filters are generally available without a prescription. A machine, or any change to pressure settings, is a different matter: those decisions belong with your sleep physician, because pressure settings are a prescription.
Do medical funds cover CPAP equipment?
Some private health insurers contribute to CPAP equipment and supplies, and policies differ widely on how much. Ask your fund what your policy includes before you buy, and ask the supplier for the paperwork your fund needs.
My mask leaks at night. What should I change first?
Start with the seal, not the machine: check cushion size, whether it is worn, and how the headgear tension feels. A fresh cushion of the same size often solves it; a different size or mask style solves the rest. A fitting appointment is the fastest route to the right answer.
How do I clean CPAP supplies?
Daily: wipe the cushion, and empty and air-dry the humidifier chamber. Weekly: wash the mask, cushions and tubing in warm water with mild soap, and check the filter. Skip anything harsh or scented, and let everything dry fully before reassembly.
