CPAP Masks for Mouth Breathers

CPAP Masks for Mouth Breathers

If you breathe through your mouth on CPAP, air escapes past a nasal mask and you wake up with a dry mouth or big leaks that cut your therapy short. The fix is a mask that accounts for the open mouth: a full face mask that seals over both the nose and mouth, or a nasal setup paired with a chin strap. We carry the full face and hybrid masks that work best for mouth breathers, from ResMed, Philips Respironics, and Fisher & Paykel. A prescription is required, and every mask is FSA and HSA eligible.

Best masks for mouth breathers

  • Full face masks: seal over the nose and mouth so mouth breathing does not break the seal. Popular picks include the ResMed AirFit F20, AirFit F40, AirTouch F20, and Mirage Quattro, the Philips DreamWear Full Face and Amara View, and the Fisher & Paykel Simplus.
  • Oral-nasal hybrid: the ResMed AirFit X30i is a full face mask with a top-of-head tube and a compact cushion, a lighter option that still covers the mouth.

Prefer to keep your nasal or pillow mask? A CPAP chin strap holds your jaw closed so you can breathe through your nose, and mouth tape is a gentler nighttime option. Read our roundup of the best CPAP chin straps to compare them, or see our full CPAP masks range to compare every style.

FAQs

What kind of CPAP mask should a mouth breather use?

Most mouth breathers do best with a full face mask, which seals over both the nose and mouth so air does not escape when your mouth falls open. An oral-nasal hybrid like the ResMed AirFit X30i is a lighter full face option. If you would rather keep a nasal or nasal pillow mask, pair it with a chin strap.

Can a mouth breather use a nasal or nasal pillow mask?

Yes, with help. A nasal or nasal pillow mask only delivers air through the nose, so a mouth breather usually needs a chin strap to hold the jaw closed, or mouth tape, to keep the pressure from leaking out through the mouth. Without one of those, you may get leaks and a dry mouth.

Why do I get a dry mouth with my CPAP?

A dry mouth is often a sign that air is leaking out through your mouth while you sleep, which is common for mouth breathers on a nasal mask. Low humidifier settings can also play a role. Switching to a full face mask, adding a chin strap, or adjusting your heated humidifier can help. Our guide to CPAP dry mouth covers the options.

Do I have to use a full face mask if I breathe through my mouth?

Not always, but it is the simplest fix. A full face mask handles mouth breathing on its own. The alternative is a nasal or nasal pillow mask plus a chin strap or mouth tape to keep your mouth closed. Comfort and fit decide which route works best for you.

Will a chin strap stop my mouth from opening?

A chin strap gently holds your jaw closed so you can breathe through your nose with a nasal or nasal pillow mask. It works well for many people, though some still prefer the reliability of a full face mask. Both are valid ways to manage mouth breathing on CPAP.

Do I need a prescription to buy a CPAP mask?

Yes. CPAP masks are prescription devices in the United States. You can upload your prescription at checkout or have your provider send it to us, and our team can help if you are not sure which mask fits your machine and your needs.

Are these masks FSA or HSA eligible?

Yes. CPAP masks, including full face masks for mouth breathers, are FSA and HSA eligible, so you can pay with pre-tax funds. Keep your receipt for reimbursement.
