Best Side Sleeping CPAP Masks

This post was originally posted on July 26, 2022 and updated on August 28, 2023.

Over the last few years, CPAP manufacturers have released many new types of masks. Choice is good for users but making the proper mask decision directly impacts compliance. The more comfortable and effective the mask, the higher use rate amongst CPAP patients. CPAP masks come in various models and styles so that each individual sleep apnea patient can decide which type works best for them as one mask which works well for one might be completely wrong for another. One major consideration in choosing a mask is whether or not the wearers are “mouth breathers.”

Why Do CPAP Users Often Have The Problem Of Mouth Breathing?

The device providing continuous airway pressure works optimally when we breathe through the nose.  Nasal breathing also reduces  evaporation and does not usually result in a dry mouth. The CPAP user often struggles to breathe through the nose, and starts mouth breathing as an alternative way to inhale more air.  The continuous mouth breathing hampers our natural airway anatomy and causes an elongated face and also results in dry mouth. The more this happens, the more difficult it is to breathe through the nose.

Generally, when recommending masks for those who breath through their mouth while sleeping (including people who have stuffy noses from colds), a full face mask is typically recommended. A full face mask offers several advantages to mouth breathers including:

  • Useful for CPAP users with pressure above 17cm H2
  • Decreased nasal passage strain especially during cold season
  • A good choice for people who sleep on their side
  • Excellent for those whose jaw drops during sleep

Mouth breathers also enjoy the benefit of less irritation to their nasal cavities, because a full face CPAP mask sends the air into both the mouth and nose. Also, CPAP users with a deviated septum or other nasal issues will benefit significantly by employing a full face mask.

If you’re using a nasal or nasal pillow mask and predominantly breathe through your mouth during sleep, it may feel as though CPAP therapy isn’t working as expected.1 When most of your breathing is done by mouth and you’re wearing a nasal mask, a reduced amount of therapeutic, pressurized air is entering your breathing passages. In fact, it flows air flows in through your nose and much is released by out through the mouth. This, in effect, is preventing you for optimizing your therapy and not providing you with its full benefit. Switching to a full face mask might provide an immediate improvement to your CPAP therapy.

Why Do Mouth Breathers Need Specific Masks?

Full-face masks are recommended for mouth breathers because the warm humid air from the humidified CPAP machine helps to keep the mouth from drying. Dry mouth can prove to be a serious issue because it can result in tooth and gum problems, and increase plaque.

Types of Full Face CPAP Masks for Mouth Breathers

The CPAP Shop carries an extensive line of full face CPAP masks for mouth breathers from top manufactures. Some of the best and most recommended choices include:
