Getting a CPAP prescription can feel like a relief — finally, an explanation for the exhaustion — right up until the first few nights of actually wearing the thing. A mask that leaks, fogs your glasses, or makes you feel like you’re drowning is one of the most common reasons people give up on sleep apnea therapy early, even though the therapy itself works.
It’s usually the mask, not the treatment
According to Mayo Clinic’s guide to common CPAP problems, mask discomfort, air leaks, and a feeling of claustrophobia are among the most frequent complaints — and nearly all of them are fixable with the right mask type, size, or fit adjustment rather than by abandoning therapy altogether. Sticking with an ill-fitting mask out of a sense that “this is just what CPAP feels like” is one of the most avoidable reasons people fall short of consistent use.
The three main mask categories
Per the Sleep Foundation’s overview of CPAP mask types, most masks fall into three groups:
- Nasal masks cover the nose only. They tend to feel less bulky and are a common starting point, but they can be uncomfortable during allergy season or a head cold, when nasal breathing becomes difficult.
- Full-face masks cover both the nose and mouth. They’re often recommended for people who breathe through their mouth at night, have nasal congestion, or need higher pressure settings — but the extra coverage can trigger claustrophobic feelings for some people, especially early on.
- Nasal pillow masks use small cushions that rest at the nostril openings. They’re the least bulky option and work well for side sleepers or people who feel smothered by more coverage, though they can feel less secure at higher pressures.
Sleep position matters too — the Sleep Foundation’s guide to choosing a mask by sleep position notes that side sleepers in particular often do better with a low-profile nasal pillow or a mask with a swivel-style tube connection that reduces tugging when they roll over.
Practical fit tips
- Sizing is not one-and-done. DME (durable medical equipment) suppliers typically carry multiple cushion sizes for the same mask model — a mask that leaks around the bridge of the nose or under the eyes is very often a sizing issue, not a defective product.
- Give a new mask a real trial, but don’t force it past discomfort. Some adjustment period is normal in the first one to two weeks; ongoing pain, red pressure marks, or genuine panic each night is a sign to go back and try a different style, not to push through.
- Allergies and congestion change what works. If your usual nasal mask suddenly feels impossible during a cold or allergy flare, a full-face mask (even temporarily) or a heated humidifier setting can help.
- Ask about a mask-fitting appointment. Most CPAP suppliers will do in-person or video fittings and are used to swapping mask styles within an initial trial window — most insurance plans build in an exchange period for exactly this reason.
Why sticking with it is worth the troubleshooting
Many insurance plans require a minimum number of hours of nightly use over a set trial period (often around 90 days) before they’ll continue covering the device — which makes the first few weeks the highest-stakes window for finding a mask that actually works for your face shape and sleep position, rather than settling for one that technically fits.

If you’re having ongoing trouble tolerating therapy, or you’re unsure whether your current settings are right for you, talk to your prescribing provider or DME supplier about your options.
