Product Details

PureSom Adjustable Breathe-O-Prene CPAP Ruby Chin Strap

The PureSom Ruby Adjustable Chin Strap is made of stretchable, breathable neoprene that holds the mouth closed during CPAP therapy to prevent air leaks out of the mouth. Chin straps prevent mouth opening which is the most common cause of dry mouth and high mask leak for nasal and nasal pillow CPAP mask users. This moisture wicking chin strap is adjustable at the crown of the head and at the base of the neck for a  customizable fit that is comfortable and effective.

Chin Strap Dimensions:

  • Standard = 22 to 24 inches
  • Extra Large = 26 to 28 inches

Fitting Instructions

  1. Open up the chinstrap, so it is flat, and make sure the thin strap points towards the top of the head. The wider strap will be on the bottom.
  2. Pull the chin cup over the chin.
  3. Close the top strap with the Velcro, adjust as needed.
  4. Close the wide back strap (this is sitting on the back of your neck), adjust the Velcro as needed.
  5. Your ears will sit in the ear cutouts.

The design of this chinstrap may inadvertently push your jaw back as you tighten the Velcro on the back of the neck. This may exacerbate your sleep apnea by increasing the number of obstructive breathing events. If this occurs, we recommend trying a dual-band chin strap such as the Knightsbridge Chin Strap.


How do I clean my PureSom Adjustable RubyChin Strap?
Hand wash your chin strap in warm water with a mild detergent or baby shampoo daily to remove any sweat and/or oils that may have accumulated overnight. While there are expensive neoprene cleaning materials available, they are usually not needed.

Do I need to use a chin strap with my CPAP therapy?
Chin straps are not a crucial component of CPAP therapy and are only necessary for those having trouble keeping their mouths closed when using a nasal or nasal pillow mask. Dry mouth/throat or dry nasal passages, despite the use of a humidifier, are common indications of mouth breathing during sleep. In these instances, we recommend wearing a chin strap under the CPAP mask to help keep the mouth closed for effective therapy.

Subject: Scratchy
The velcro part at bottom of neck is scratchy. Tighten more to get an overlap which helps the irritation but then it’s too tight. The chin part comes just below the lips. Works but is uncomfortable.

If this is the best, hard to believe. Comes with no directions and not obvious how to put on. Rubbing hair off my head since large area contacts your hair right in front where you do not want to loose it. Leaves lots of marks; contrary to what others say.

How do I determine which size to get?

Here are the sizing gauge numbers from chin to crown of your head. I would suggest upsizing for this does wrong small.
Small = 23" - 25"
Medium = 25" to 27"
Large = 27" to 29"
