    The FlexiFit HC431 Full Face CPAP Mask with Headgear by Fisher & Paykel offers several features unique to the FlexFit family. The cushion seals under the chin to offer a stable seal while the Glider Strap maintains stability during movement.

    Product Features

    The FlexiFit HC431 Full Face CPAP Mask with Headgear, part of the FlexiFit family of CPAP masks by Fisher & Paykel, includes an under chin design with Glider™ Strap to make it easy to fit and use. This is a full face mask and covers both the nose and mouth.

    Features

    • FlexiFit™ Technology
    • Unique Glider™ Strap
    • Under-Chin Design
    • Advanced Air Diffuser
    • Crown Strap on the headgear
    • Easy Release Headgear Strap

    FlexiFit Technology & Glider Strap

    Fisher & Paykels FlexiFit cushion technology allows the HC431 to contour to the surface of the face to provide a good seal. With movement during sleep, the Glider Strap allows the head to shift without disturbing the seal. The headgear strap maintain equal pressure as the head moves side to side.

    Under-Chin Design

    The Under-Chin Design offers stability by basing the seal on the jaw. If there is jaw movement during sleep, the mask seal remains.

    Efficient Air Diffuser

    The air diffuser vents the exhaled air. The design of the diffuser helps to avoid air blowing directly on a bed partner. Further, the directional tiny holes help to make the exhaled air quiet to increase sleeping comfort.

    Headgear Design Features

    The headgear of the HC431 includes a crown strap which offers greater stability and works in conjunction with the under-chin cushion design. A unique design feature of the headgear is an easy release strap allowing the mask to be removed in a single step.

    The headgear of the HC431 is latex free, as are all other headgear by Fisher & Paykel.

    Important Tips

    Sizing Guide: Per the manufacturer the HC431 uses the same sizing guide as the HC432. When opening the sizing guide on this product page, only HC432 is listed on the guide. It is the sizing guide intended for both the HC431 * Hc432.

    HC432 and HC431 Compatibility

    432 silicone cushion and foam cushion insert will not fit the 431 frame.

    431 silicone cushions made after April 2006 will fit the 432 frame.

    431 silicone cushions made before April 2006 will not fit the 432 frame.

    If you are switching from the HC431 to the Flexifit™ HC432 mask, the sizes run a little smaller on the HC432.

    The manufacturer has stamped the part number (431 or 432) identifying the mask on the upright bar for the forehead support. The manufacturer did not include the alpha characters "HC" in front of the numeric characters.

    Where do I find the size?

    The mask frame does not have an identifiable size because it offers a universal fit to each of the HC431 full face cushions.

    To find the size of the cushion, turn the mask to look at the flat bottom of full face cushion. Large embossed letters spell out the words "S M A L L," "M E D I U M," or "L A R G E." The words are found near the rim connecting the mask frame to the full face cushion.

    Do you have a guide to help me choose the right mask?
    Yes, we created a Help Me Choose guide to help you select the right mask or machine according to your preferences. The guide asks you a series of questions regarding your preferences and your facial features. Based on your answers we provide you with a comparison chart of the masks that meet your criteria. Get started here:

    Help Me Choose - Mask
    How often should I replace my mask?
    Medicare allows for mask cushion replacement every three (3) months, and a complete mask system replacement every six (6) months. CPAP manufacturers and vendors suggest these replacement schedules as well.

    In our experience, most mask cushions begin to deteriorate after about six months of use. The cushion eventually becomes too soft to hold a seal. The headgear straps lose elasticity and must be tightened more and more to get the same quality seal.

    We strongly suggest replacing cushions and pillows as soon as they start to soften. Air leaks may reduce the effectiveness of CPAP therapy and headgear that is too tight may cause facial sores at pressure points. In most cases, replacement headgear is available if it is stretched out or the Velcro worn out.

    To see what parts of your mask are replaceable refer to our Replacement Part Finder. Just search for your mask to see all of the replaceable parts.
    Why do I wake up with dry eyes?
    Air leaking from the mask at the bridge of the nose and over the eyes during sleep will cause the eyes to dry out. The most common reason for air leaking at the nose bridge is that the mask is too big or too long for the nose.

    We would suggest you resize your mask to be sure you have the best fit. A mask that has an adjustment at the bridge may also be helpful in getting a good fit. Nasal pillow or nose cushion devices which do not rest on the nose are also an option.

    It is not advisable to tighten the headgear to eliminate the air leak. Pressure from a mask that is too tight will cause bruises and even open sores if applied long enough.
    How do I care for my mask?
    Masks should be washed daily with warm water and gentle soap or baby shampoo. Let the mask air dry. Never use antibacterial soap as it will break down the silicone of the mask cushion. Avoid soaps that include lotion which can coat the mask and cause it to lose its seal. A safe cleaner is the Control III Disinfectant CPAP Cleaning Solution. Remember, going to bed with a clean face will improve your seal and protect the lifespan of your mask. Citrus Mask Wipes
    The best time to clean your mask is in the morning after use. This removes the oils left behind from your skin which can reduce the lifespan of your mask. We recommend using Mask Wipes to make daily morning cleaning easy. The mask wipes are made from materials that will not break down your mask.
    Citrus Mask Wipes
    What does a mask prescription need to say?
    A mask prescription must contain all of the following information:
    • One of the following words or phrases: "CPAP Mask", "CPAP Supplies", "CPAP Humidifier", "CPAP", "Continuous Positive Airway Pressure", "APAP", "AutoPAP", "AutoSet", "Auto CPAP", "Auto Adjusting CPAP", "Self Adjusting CPAP", "BiPAP", "BiLevel", "VPAP", "BiPAP Auto", "BiPAP ST", "Synchrony ST", "VPAP ST"
    • Your physician's contact information
    • Your physician's signature
    • The patient's full name
    Are prescriptions required for mask, machine and/or humidifier purchases?
    Yes. Federal law requires we have a valid prescription on file before we ship your mask, machine and/or humidifier.

    We provide many easy ways to get your prescription:
    • We can request your prescription for you! When you checkout, just let us know you would like us to request your prescription, or you can log into your account to have us request your prescription.
    • Fax your prescription to our toll free fax number: 866.353.2727, or our international fax number: 713.541.7370
    • Email your prescription to cpap@cpap.com
    • Upload your prescription in your account, under the Prescriptions Section
    For more information on prescriptions, please see our Prescription Section of the Learning Center.
    Why might I need a full face mask?
    If your mouth drops open during sleep, a full face may be selected to allow for the CPAP airflow to be delivered through both the nose and mouth.

    Some CPAP users move to using a full face mask after finding that using a nasal mask along with a chinstrap does not meet their sleep therapy needs. Some CPAP users use a full face mask when suffering from seasonal allergies.
    Are the FlexiFit HC431 and HC432 cushion sizes interchangeable on the mask frame?
    All FlexiFit HC431 and HC432 cushions and mask frames are interchangeable. The silicone cushions are interchangeable, but the foams will not work with the 431.
