How do you sleep?

What This Tool Does

This quiz evaluates five factors that determine which CPAP mask type will fit your face, match your breathing pattern, and stay sealed through the night. It considers your sleep position, whether you breathe through your mouth, your prescribed pressure range, whether you have facial hair, and your comfort preference for face coverage. Based on your answers, the quiz scores four mask categories and recommends a primary type with specific product suggestions.

The Four CPAP Mask Types

Nasal Pillow

Nasal pillow masks use two small silicone inserts that sit at the entrance of each nostril. They are the lightest and least obtrusive mask type, with nothing touching the bridge of the nose or forehead. Nasal pillows work well for side and stomach sleepers because there is almost no material to press into the pillow. They also tend to seal better with facial hair because the contact area is small and isolated to the nostrils. The main limitation is pressure tolerance: at higher pressures (above 14 cmH2O), the direct airflow into the nostrils can feel uncomfortable, and leak becomes harder to control.

Nasal Cradle

Nasal cradle masks rest under the nose with a curved cushion that seals around the base of the nostrils without inserting anything into them. They are a relatively new category, pioneered by masks like the ResMed AirFit N30. Cradle masks share many advantages of nasal pillows (low profile, minimal contact, good for side sleepers) while distributing pressure more evenly across the cushion surface. Some users who find nasal pillows irritating after several hours prefer the cradle design because it avoids direct nostril contact.

Full Face

Full face masks cover both the nose and mouth with a single cushion or a dual-wall seal. They are the only mask type that fully accommodates mouth breathing: if your lips part during sleep, a full face mask keeps the pressurized air contained. Full face masks also handle higher pressures well because the larger cushion surface area distributes the force. The trade-off is bulk. Full face masks have more headgear, more contact surface, and a larger profile that can shift when pressed against a pillow. They are typically the best choice for back sleepers who breathe through their mouth or use pressures above 14 cmH2O.

Hybrid

Hybrid masks combine a nasal interface (usually a cradle or pillow design) with a mouth cover. They aim to provide the mouth-leak protection of a full face mask with a less bulky frame. The ResMed AirFit F30i is a common example: it uses a nasal cradle cushion with a lower face shell and routes the tube over the top of the head. Hybrid masks can be a good compromise for users who occasionally breathe through their mouth but find traditional full face masks too heavy or claustrophobic.

How the Quiz Works

The quiz uses a weighted scoring system across five questions. Each answer adds or subtracts points from each of the four mask type categories. After all five questions, the category with the highest score becomes the primary recommendation. If a second category also scores above zero, it appears as an alternative option. In a tie, the quiz favors the less invasive mask type (nasal pillow over cradle, cradle over hybrid, hybrid over full face).

The heaviest-weighted factors are mouth breathing and coverage comfort. If you breathe through your mouth, nasal-only options receive a significant penalty because they cannot contain the air escaping through parted lips. If you are uncomfortable with face coverage, full face masks receive a large penalty. Sleep position and pressure range provide secondary weighting, and facial hair acts as a tiebreaker that favors nasal pillows (which seal at the nostril rather than against skin).

Choosing the Right Mask Size

Once you know your mask type, the next step is getting the right size. Most mask manufacturers provide printable sizing guides that you hold against your face. ResMed, Fisher & Paykel, and Philips all have sizing templates available on their websites. As a general rule: a mask that is too large will leak at the bridge of the nose or around the chin, while a mask that is too small will require over-tightening to seal, leaving pressure marks. If you are between sizes, the smaller size typically seals better because the silicone can stretch slightly to conform to your face. Your DME (durable medical equipment) supplier should fit you in person before your first prescription, but for replacement masks purchased online, the sizing templates are your best reference.

Frequently Asked Questions

How often should I replace my CPAP mask?

Most manufacturers recommend replacing the mask cushion every 1 to 3 months and the full frame every 3 to 6 months. Medicare covers replacements on a set schedule: nasal cushions every 2 weeks, full face cushions monthly, and frames every 3 months. In practice, replace the cushion when you notice increased leak or visible wear, and replace the frame when headgear stretches out or buckles crack.

Can I switch mask types without changing my machine settings?

Yes. All modern CPAP machines work with any mask type. Some machines (including all ResMed AirSense models) have a mask type setting that adjusts leak compensation algorithms. If you switch from a nasal mask to a full face mask, update the mask type in your machine settings so the leak calculation stays accurate. The setting does not change your therapy pressure.

What should I do if my mask leaks even though it feels comfortable?

First, check whether you are over-tightening the headgear. A common mistake is cranking straps down to stop a leak, which actually distorts the cushion shape and makes leaks worse. Loosen the headgear until the mask barely stays on your face, then slowly tighten until the seal forms. If leak persists, the cushion may need replacement, or the mask size may be wrong. Most manufacturers offer sizing templates you can print at home.

Do I need a full face mask if I breathe through my mouth?

A full face mask or a hybrid mask is the most reliable option for mouth breathers because it covers both the nose and mouth, preventing air from escaping through parted lips. An alternative is using a nasal or nasal pillow mask with a chin strap, which holds the jaw closed. Some users find chin straps uncomfortable or ineffective, so trying a full face mask first is usually the simpler path.

Which mask type works best for side sleepers?

Nasal pillow and nasal cradle masks are generally the best choices for side sleepers. Their low profile means less material presses into the pillow, reducing leak and pressure marks. Full face masks can work for side sleepers, but bulkier frames tend to shift when pressed against a pillow. If you prefer a full face mask, look for a model with a top-of-head tube connection, which reduces tube drag when turning.
