CPAP treats sleep apnoea, not snoring.
A CPAP machine is a medical treatment for obstructive sleep apnoea. It isn’t something to buy for snoring, and nobody should be using one without a diagnosis.
Why it shows up in snoring searches
Most people with sleep apnoea snore, so the two words travel together. But snoring on its own is not sleep apnoea. The machine keeps the airway open with gentle air pressure through a mask all night, which solves a breathing problem. For simple snoring without breathing pauses it is rarely the first choice, but one guideline does list it: Australia’s 2023 position statement on primary snoring says CPAP should be considered if the person is willing to try it or already uses it, and notes that low pressures have been shown to stop snoring in people without apnoea. It is a treatment prescribed and set up through a sleep service, not something to buy.
What the guidelines say
- The US sleep medicine society recommends PAP for adults with sleep apnoea who are sleepy in the day Guideline-backed. Fixed-pressure CPAP and auto-adjusting APAP are treated as equivalent for ongoing use.
- England’s NICE guideline offers CPAP to people with moderate or severe sleep apnoea, and to mild cases only when symptoms affect daily life. Mild sleep apnoea without daytime symptoms usually gets lifestyle advice first.
- Neither guideline covers simple snoring.
You only get to this option after a sleep study. If snoring is your only symptom, the study is what tells you whether a machine is relevant at all. Buying one first skips the question that matters.
Who decides, and what it costs
A sleep physician, after a sleep study. How you pay differs a lot by country: in England the NHS supplies CPAP; in Australia Medicare covers the sleep study and consultations but not the machine itself, which comes through state programs, private cover or your own pocket; in the US it usually runs through insurance, often with usage requirements. We haven’t verified current prices anywhere.
If you’re already on CPAP and still snore
That’s worth telling the clinic. Snoring with the mask on can mean a leak, a pressure that needs adjusting, or mouth breathing. It isn’t something to fix with a strip or a mouthpiece on top.
Original sources & their limits
- Treatment of adult OSA with positive airway pressure: AASM clinical practice guideline (2019), summary ↗
AASM one-page summary read. Full guideline: Patil et al., J Clin Sleep Med 2019;15(2):335-343. PAP is recommended for adults with OSA and sleepiness (strong); CPAP and auto-PAP are treated as interchangeable for ongoing use.
- NICE guideline NG202: obstructive sleep apnoea/hypopnoea syndrome in over-16s (2021) ↗
Read from a hosted copy of the guideline PDF (the NICE site refused our fetch). Offers CPAP for moderate or severe OSAHS; for mild OSAHS only when symptoms affect daily life; mandibular advancement splints when CPAP is not tolerated; positional modifiers for mild/moderate positional OSAHS. It does not cover simple snoring.

Retailer page, read for one fact only: Medicare does not subsidise CPAP machines nationally; support is through state programs, private extras or DVA. Commercial source; confirm with your doctor.
- Australasian Sleep Association position statement on consensus and evidence based treatment for primary snoring (Sarkis et al., Respirology, 2023) ↗
Full text read, 2026-10-26, from the open-access copy. The only recent guideline written specifically for snoring without significant sleep apnoea. Grades each option: mandibular advancement devices first line (Level B, high certainty); CPAP an option for people willing to try or already using it (Level B); positional therapy reasonable (Level C); weight loss and less alcohol recommended (Level D); mouth and throat exercises low risk, small effect (Level B, low certainty); radiofrequency palate surgery safe and effective short term (Level B); over-the-counter nasal dilators, sprays and herbal remedies not advised (Level D, low certainty). Nasal strips and mouth taping are not addressed.
