Any CPAP mask headgear can be used with this universal size chin strap to help stop leaks that could result in dry mouth and noses.
For nasal mask wearers who find their jaw or mouth opening while they sleep, chin straps are helpful. For the therapy to be effective, the mouth must remain closed when wearing a nasal mask.
Guidelines for Cleaning
For the chinstrap to keep its comfort and shape, we advise washing it with light soap and letting it air dry entirely. It might be necessary to make minor changes to your chinstrap after multiple washings. Your chinstrap should not be machine washed, dried, or ironed.
