    Product Overview

    The PAPcap Plus is a comfortable solution to "mouth breathing" that incorporates both a chinstrap and 4 point headgear. Rid yourself of ineffective chinstraps that just add additional bulk to your face. The PAPcap Plus replaces your current headgear while providing a comfortable chinstrap that secures the jaw and helps keep the lips closed.

    Manufactured by Pur-Sleep.

    Product Features

    The PAPcap Plus combines a revolutionary chinstrap and an attachable four point headgear that works with most nasal and full face CPAP masks.


    A 100% cotton cap conforms around your head and uses Velcro to secure a pair of backstraps behind the head with the cap flap tucked under. Excess hair can be pulled through the space beneath the flap and backstraps. The bottom of he cap can be rolled up, inside the cap, to improve fitting around the ears and eyes.


    Install the chinstrap under your jaw using the large Velcro pad on both sides of the cap. The cotton cap and soft flannel chinstrap provide comfortable padding around your face while helping to stabilize your jaw. Adjust the chinstrap using the Velcro attachments on the cap. A relatively small amount of tension works best. The chinstrap is designed to provide vertical support, from the top of your head; whereas, most chinstrap pull diagonally from the back of your head, which puts stress on the jaw and can impede CPAP therapy.

    Headgear Attachments

    The PAPcap Plus comes with two sets of RipStrip Velcro loops that replace your standard headgear. Attach the RipStrip loops to each of the four points on the mask and affix the top loops onto the cap and the bottom loops onto the chinstrap. Use the metal hook extensions to secure the chinstrap and prevent the mask from slipping.


    The cap comes in two sizes, Small/Medium and Large/Extra Large. The Small/Medium cap fits most users and the Large/Extra Large is deeper and provides an additional half inch in length.

    The PAPcap Plus also comes with a Velcro tube retainer that helps secure over-the-head tubing for mask attachments like the Inlet Tube with Swivel Assembly.

    Frequently Asked Questions (FAQs)

    I breathe through my mouth, what are my options?
    People who have a deviated septum, small nostrils, or who suffer from seasonal allergies or chronic sinus issues, may breathe through the mouth rather than the nose. If you are a person who breathes through your mouth you may be able to wear most masks with a few adaptations. Add a Chinstrap if using nasal pillows, nasal prongs or a nasal mask.
    Sullivan 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. 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:

    Hybrid Masks
    Oral Masks
    Full Face Masks

    Why is my mouth dry in the morning?
    Dry mouth is a sign that you are opening your mouth while you sleep. If you use a nasal mask, breathing through your mouth bypasses any humidification you may be using so increasing the heat will not be effective. Breathing through your mouth while using a nasal mask reduces the benefit of CPAP therapy.

    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
    Heated Tubing
    What is the purpose of a chinstrap?
    Nasal delivery devices are the preferred mode of delivering CPAP air. They are smaller, lighter and usually more comfortable, with many styles and sizes to choose from.

    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
    What styles of chinstraps are there?
    A basic chinstrap cups the chin and has narrow straps that connect at the top of the head, usually with Velcro. It works best for those who sleep on their side and who do not open their mouth very much. The straps may fall forward or backward on the head if not held in place by the mask headgear. An example of this type of chinstrap is the Sullivan Chinstrap.Sullivan 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.Sullivan 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 Deluxe Chinstrap. Deluxe Chinstrap
    Why is air leaking from my mouth?
    Air leaks from the mouth whenever the mouth is opened during CPAP therapy. This occurs for many reasons, but a very common one is due to nasal irritation from the CPAP airflow.

    The correlation between the lack of humidification and mouth leaks is a topic being heavily researched. Studies are now being conducted on the hypothesis that a large 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 that covers the nose and mouth is indicated.
