Which Type of CPAP Mask Should I Choose?
There are three main types of CPAP masks:
There are three main types of CPAP mask — full face, nasal, and nasal pillow — and the right choice depends primarily on how you breathe at night and how you sleep. This page gives you a quick overview. If you want the full breakdown, including hose connection types, sizing, and advice on facial hair or claustrophobia, see our complete CPAP mask selection guide.
The Three Main Types of CPAP Mask
1. Nasal Pillow Masks
The most minimal option. Small silicone tips sit just inside the nostrils — there's almost no contact with the rest of the face. Great for active sleepers, side sleepers, and anyone who feels claustrophobic in larger masks.
Best for: Nose breathers, side sleepers, people with facial hair, lower to moderate pressure settings.
Not suited to: Mouth breathers, high-pressure settings, frequent nasal congestion.
2. Nasal Masks
A cushion that covers or sits just below the nose, delivering airflow through the nasal passages only. More stable than nasal pillows at higher pressures, lighter than a full face mask. Modern under-the-nose designs eliminate nose bridge pressure entirely.
Best for: Nose breathers, moderate to higher pressure settings, back and side sleepers.
Not suited to: Mouth breathers (without a chin strap).
3. Full Face Masks
Covers both nose and mouth, so mouth breathing during sleep isn't a problem. The go-to choice for mouth breathers, people with frequent congestion, and those on higher pressure settings. Modern designs are far less bulky than older full face masks.
Best for: Mouth breathers, high-pressure settings, nasal congestion, anyone whose nasal mask leaks overnight.
Not suited to: Users who are strongly claustrophobic (without an adjustment period).

The Single Most Important Factor: Mouth vs. Nose Breathing
Everything else being equal, how you breathe during sleep determines your mask type more than anything else. If your mouth falls open at night — even occasionally — a nasal or pillow mask will let pressurised air escape, leaving you with a dry mouth and reduced therapy effectiveness. A full face mask solves this directly. Alternatively, a CPAP chin strap can help keep the mouth closed if you prefer a nasal style.
Not sure which you are? Waking up with a dry mouth or sore throat is a reliable sign your mouth is opening during sleep.

Frequently Asked Questions
Can I switch mask types once I've started CPAP therapy?
Yes — and many users do. You might start on a full face mask and move to a nasal mask once you're comfortable, or discover your mouth stays closed naturally after a few months of therapy. There's no obligation to stay on the same mask type.
Will my health fund cover a CPAP mask in Australia?
Many Australian private health funds include CPAP equipment — including masks — under extras cover for sleep apnea treatment. The rebate level varies significantly between funds and policies, so check your specific cover. Keep your receipts, as most funds require a claim to be submitted after purchase.
Do CPAP masks fit all CPAP machines?
Most masks use a standard 22mm cuff connector and are compatible with the vast majority of CPAP, APAP, and BiPAP machines. The main exception is the ResMed AirMini travel CPAP, which requires specific ResMed mask adapters due to its compact design.
