If you have or develop chronic sinus problems, a full face mask or an oral face mask are the ones to try. Oral masks work best for mouth breathers with blocked nasal passages. You must use a heated humidifier with the oral mask. CPAP.com sells the Oracle HC452 Oral CPAP mask.
If you are a mouth breather who does not want to or cannot wear a chinstrap, please see our recommended masks for Mouth Breathers.
First, be sure the mask is not leaking. If the mask is six to nine months old and leaking, try replacing it. If it is new and leaking, the fit could be incorrect. We can help you find a mask with a great fit.
If your mask is new and NOT leaking, try a Chinstrap to keep your jaw up and mouth from dropping open during sleep. If a chinstrap doesn't solve the problem, try masks recommended for Mouth Breathers.
If you use a full face mask and have a dry mouth, try adding a Heated Humidifier to add moisture.
Here are some items we recommend that may help with dry mouth:
Heated Humidifiers
Full Face Masks
Chinstraps
Heated Tubing
The correlation between a lack of humidification and mouth leaks is a topic that has been heavily researched. The hypothesis is that a significant amount of mouth leakage is caused by the following cycle:
- CPAP therapy is used with ineffective or no humidification,
- The nasal membranes are unable to adequately condition the increased airflow and after a few minutes the airway and nasal passages become dry.
- To remedy the dryness and obtain moisture, the body uses the mouth to breathe.
- CPAP air follows the path of least resistance and leaks out of the open mouth.
- The air leaking through the mouth causes more dryness.
- Patient wakes up feeling tired with significant dryness in mouth and dry, swollen nasal passages.
The answer to this cycle is humidification. If the mouth continues to open during sleep, a Chinstrap may be needed to hold the jaw up so that the mouth can close. If mouth breathing continues, a full face mask, hybrid mask, or oral mask is suggested. See our recommended masks for Mouth Breathers.
When using a nasal device with a CPAP, it is imperative that the mouth remain closed for the pressure to be maintained and the therapy to be effective. Most people will automatically keep their mouth closed while on CPAP, but some are unable to do so, at least in the beginning of the therapy.
Use of a Chinstrap is the first response to opening the mouth during sleep. It is worn in addition to the CPAP mask to hold the jaw up and help keep the mouth closed.
Even with the use of a chinstrap, some people are still able to breathe through their teeth and lips. If so, a Full Face Mask is an option worth considering.
Here are some recommended chinstraps:
Ruby-Style Adjustable Chinstrap with Extension Strap
Deluxe-Style Chinstrap
Premium Chinstrap
Halo Chinstrap

For greater strength, a wider chinstrap is available. The width of the strap is sufficient to cup the chin, and narrow straps are available to attach across the forehead to keep the chinstrap from falling back, as well as across the back of the head to keep it from falling forward. This style of chinstrap is more stable, but it may cover the ears. An example of this type of chinstrap is the Premium Chinstrap.

Another style of chinstrap is a series of straps that cup the chin at a lower angle for greater support, and include the stabilizing straps in the design. An example of this type of chinstrap is the CPAP.com Deluxe Chinstrap.


A full face mask or hybrid mask can be used without a chinstrap because the seal covers both the nose and mouth. A full face mask will allow you to breathe through your mouth or through your nose.
If you suffer from chronic sinus issues, a full face mask or an oral face mask are good options. Oral masks work best for mouth breathers with blocked nasal passages. You must use a heated humidifier with the oral mask. CPAP.com sells the Oracle HC452 Oral CPAP mask.
If you are a mouth breather who cannot or who does not want to wear a chinstrap, please see our recommended masks for Mouth Breathers.
Here are some suggested items that may help with mouth breathing:

If you use a full face mask and have a dry mouth, try adding a heated humidifier to add moisture.
The strap is comfortable but the velco is starting to pill
More compact than previous chin straps, so more comfortable and works fine.

I was using the sullivan chin strap, and it was pretty good. It was time to reorder so I thought I would try this Navillus strap. It is much more comfortable. The side straps have a little bit of elastic so it's not a stiff strap. The soft chin cup is very soft and stretchy. It conforms to your chin and doesn't roll. I wear the swift fx mask, and it's perfect with that one. I recommend this strap. ***** five stars! more...
Strap narrower than depicted in picture. Velcro so sticky it began to unravel and stick to opposite strap after one use. Stitching on chin cup too thick, uncomfortable. Was given refund. Going back to Sullivan Chin Strap. more...
Excellent product, solved my problem!!
