Comfortable Chinstrap for Secure Mouth during CPAP Therapy

The PURESOM Ruby Adjustable Chin Strap is made up of a comfortable neoprene material that will hold your mouth and chin in place during CPAP therapy, reducing airflow leaks out of the mouth. The sleep apnea chin strap is adjustable at two different spots so that the user can have a customizable fit that is both comfortable and effective.

Two different sizes
The PURESOM Ruby Adjustable Chin Strap is available in standard and extra-large, giving the user multiple options for different head sizes and types. 

  • Standard = 22 - 24 inches
  • Extra large = 26 to 28 inches

Velcro Adjustments
Velcro makes adjusting the sleep apnea chin strap hassle-free while also reducing pressure on the face, resulting in a more comfortable night's sleep during CPAP therapy. This allows the sleep apnea chin strap to have a customizable fit that will reduce or completely eliminate airflow leaks out of the mouth during the night.

Fitting Instruction

  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 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. If this occurs, we recommend trying a dual-band chin strap such as the Knightsbridge chin strap.

Key Features

  • Three-point design - Ensures that you have correctly aligned your PureSom chin strap while supporting the chin with the least amount of discomfort possible
  • Two different sizes - Available in standard and extra large to provide versatility
  • Two different adjustment points - At the crown of the head and base of the neck for a custom fit every time

Reviewers Tip:
I was having trouble with keeping my mouth closed during CPAP therapy, having a lot of mouth leaks at night resulting in waking up with a dry throat. This chin strap was great because it is adjustable, allowing me to tighten or loosen it at my discretion very easily in order to make sure that my chin was secure while not sacrificing comfort. There are two different adjustment points, one on top of the head, and one at the bottom of the chin near the neck, which allowed me to adjust in both spots so that I could find the perfect fit.


What are some of the possible side effects of breathing out of the mouth during CPAP therapy?
Breathing out of the mouth can cause discomfort after using your CPAP machine, most notably a dry mouth or dry nasal area, as the airflow will leak out of the mouth during the night. Chin straps are designed to secure the mouth in place, while not interfering with your CPAP mask.

Do I need a chin strap to use my CPAP mask?
No, chin straps are not required during CPAP therapy, and they might not be for everybody. We recommend a chin strap if you are having a problem keeping your mouth closed during the night and therefore experiencing leaks. You might not know whether or not your mouth is open during the night, but if you are experiencing a dry mouth or a dry nose in the morning even if you're using a heated humidifier and heated tubing, it is possible that your mouth tends to open during the night and a chin strap might work for you.

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.

I had problems with my old chinstrap but once I switched to the Carefusion chinstraps I realized that my old one (Best in Rest chinstrap) was just bad and the one I'm using now should be the standard for all chinstraps.

With my old chinstrap, it used to fall off every night. In the morning, I would notice it's not on my face anymore and I would have to find where it is on my bed. My old chinstrap didn't work at all but I was so used to it that I thought that was normal. When I changed to the Carefusion chinstrap I was so surprised that it was still on my face every morning. It does its job very well and I have never experienced it fall off during the night.

The Carefusion chinstrap is also made very sturdy unlike my old chinstrap. I can tell the material is also very nice because it is soft but it is a very strong material.

There are only two main problems I have with this chinstrap. First, it's that after I wash my hair (I have long hair), it becomes more difficult for the chinstrap to stay on my face. I air dry my hair so maybe this has to do with it. Also I don't think this is a problem with only this chinstrap; other ones would also have the same problem. Second, two visible lines show up on my face in the morning from the chinstrap. This shows how tightly the chinstrap rests on my face throughout the night. It really does its job but I sometimes feel self conscious about the lines. They usually stay for about a few hours before they fade away.

Overall I am very satisfied with my chinstrap. I think this is probably one of the best you can get on the market for this price. I would highly recommend this to anyone looking for a chinstrap.

Very comfortable to wear. Over time, the velcro will weaken, but the material is soft and doesn't leave pressure marks on the face.

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.

Great product, best adjustable chin strap I have ever purchased

I bought this chin strap after talking with a Respshop representative. It does the job, and 2 good things to note are that it doesn't leave pressure marks on your face, and the velcro doesn't get tangled in your hair.
