CPAP masks for open mouth breathers

ResMed AirFit F20 full face CPAP mask for mouth breathers

With a nasal mask, air escapes when your mouth falls open, and you wake with a dry mouth. A full face mask solves that. The choice is between a traditional cushion over the nose and a smaller one that sits under it.

Hybrid masks

Masks that cover the mouth and seal under the nose are sometimes called hybrid masks. On this page those are the AirFit F40, AirFit F30, DreamWear Full Face and Evora Full Face.

Dry mouth on a nasal mask

If you like your nasal mask but wake with a dry mouth, a chin strap can hold your mouth closed. If that does not work, move to a full face mask.

FAQs

What is the best CPAP mask for mouth breathers?

A full face mask. The ResMed AirFit F20 is the most widely used. If you want less on your face, the AirFit F40 and the Philips DreamWear Full Face cover the mouth and seal under the nose.

Can I use a nasal or nasal pillow mask if I breathe through my mouth?

Only if you can keep your mouth closed, for example with a chin strap. If air still escapes through your mouth, the pressure drops and therapy is less effective, so a full face mask is the better choice.

What is the best CPAP mask for a side sleeper who breathes through the mouth?

A full face mask with the tube at the top of the head, such as the Philips DreamWear Full Face or the ResMed AirFit F30i. The hose stays off the pillow when you turn.

What is a hybrid CPAP mask?

It is a mask that covers the mouth and seals under the nose instead of over it. The AirFit F40, AirFit F30, DreamWear Full Face and Evora Full Face are all this style.

Do I need a prescription to buy one of these masks?

Yes. Every complete CPAP mask is sold by prescription. Place your order, then email a copy of your prescription to info@orderyoursupplies.com and include your order number so we can match it. Replacement cushions, headgear and mask kits sold without headgear do not need a prescription.

Can I return a mask if it does not fit?

Only if it is unused. We accept returns within 30 days of delivery when the mask is still in its sealed original packaging; a mask that has been opened or worn cannot be returned. Approved returns are refunded minus a 20% restocking fee, or you can take store credit. If you are between sizes, a fit pack includes more than one cushion size.
