    Parts Of A CPAP System

    A basic CPAP setup consists of a CPAP machine, hose and CPAP mask. The CPAP machine and CPAP mask are attached to either side of the hose. The CPAP machine blows air into the hose and through the mask to you.

    CPAP Equipment FAQs

    What is CPAP therapy?
    CPAP stands for Continuous Positive Airway Pressure. CPAP therapy is the most commonly recommended, and the most effective, treatment for obstructive sleep apnea.

    A CPAP machine provides air at a constant prescribed pressure. The air is delivered to the person through a tube and a CPAP mask. CPAP therapy provides a constant airflow which keeps the airway open so uninterrupted breathing is maintained during sleep. The air stream eliminates Sleep Apnea events and allows the person to get a restful sleep.

    The level of air pressure required to maintain your airway is determined during your sleep study. Your doctor will write a prescription for a CPAP machine set at that pressure.

    CPAP therapy is delivered through a nasal mask that seals around the nose or nasal pillows which seal at the nasal opening. Full face masks are available for a person who breathes through both the nose and mouth. Many innovative and comfortable options are available and advances in the delivery of CPAP therapy are continually occurring.

    For instance: Some machines offer a comfort feature such as FLEX or EPR technology. It provides exhalation relief, a slight drop in pressure at the time of exhalation to help make therapy more natural. APAP, BiPAP and BiLevel machines offer various levels of pressure throughout the night.

    What comes with my machine?
    Machines come with a six foot hose, power cord, at least one filter, and manuals. Most manufacturers include a carrying case which is designed specifically for their equipment. CPAP, APAP, and BiPAP machines do not come with a delivery system or mask. CPAP masks must be purchased separately.

    To see the list of what specifically comes with each machine, you can Browse for a machine. Then on the product page, click the "Specs" tab to see a full list of what comes with the machine.

    How can I find replacement parts for my CPAP machine?
    Wondering which filters work for your machine? Or trying to find the right replacement power cord? To find what parts are compatible with your machine or to find what parts of your machine are replaceable you can:
    • Use our Replacement Part Wizard to identify your machine and see all the related parts.
    • Browse for your machine and then click the "Replacement Parts" button on your machine's product page.
    What type of power does my CPAP need?
    Most CPAP and BiLevel machines today are designed to operate on both AC and DC voltage. In the United States, the AC current from a wall outlet is 110 volts. Overseas, the AC current is usually 220 or 240 volt. Most batteries produce 12 volt DC current.

    We include information about the power needs and capacities on the CPAP.com pages our products. Please see the "Power" tab on any machine product page for this information. You can also see a summary of the voltage range and whether it is DC capable on our Compare Charts.

    Here is a video explaining differences in power cords and power supplies of various CPAP machines:

    What maintenance is required on machines?
    The only care a CPAP or BiPAP machine requires is to clean or change the filters at the air intake. This keeps the internal parts from accumulating dust. Fine paper filters should be changed out every 30 days, or when they appear soiled. Foam washable filters should be rinsed with clear running water once a week, allowed to air dry, and reinserted.

    Here are some other suggested actions to care for your machine:
    • Keep the area around your machine clean by removing any dust from the area to improve the air quality delivered to your machine and to you.
    • Keep the air intake of the machine unblocked. Curtains, bedding, and papers can easily block the air intake of your machine, reducing the airflow.
    • If a humidifier is used with your therapy, do not pick up the machine with the humidifier attached. With most machines it is easy to spill water from the humidifier chamber into the machine causing damage. Manufacturer warranties are voided by water damage to the machine. To avoid this, remove the chamber from the humidifier and then remove the humidifier from the machine rather than transporting them together.
    • If a humidifier is used, empty the water from the chamber every morning. Accidents happen. If a family pet or family member moves the machine and humidifier with water in the chamber it is more likely that water could be spilled into your machine. Water damage to a machine voids the manufacturer warranty.
    What is humidification?
    Humidification adds moisture to the CPAP air, reducing irritation to the nasal passages caused by the increased airflow.

    CPAP air is an irritant - to one degree or another - to everyone. In some cases the irritation dries out the nasal passages and may cause bleeding. It may also cause swelling, excess mucous, congestion or sneezing. The irritation may create a very fertile ground for infections to begin. The irritation may be cumulative, building up over time. The only way to reduce the irritation is to add moisture.

    Humidification is therefore a critical part of CPAP Therapy.

    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

    • Sizing Guides. Many Nasal and Full Face masks have sizing guides available to help determine the size needed. Simply print the sizing guide, cut out if needed, and use a mirror or helper to look at the guide to see if it is a proper fit on the face. Please note, to ensure the guide is the proper size, it should be printed in PDF format at 100% scale, meaning "Fit to Page" may have to be disabled.

    • Return Insurance. With every mask we sell, you have the option of purchasing return insurance. Masks are FDA approved medical devices. Once a mask is used, it cannot be resold to another customer. CPAP.com was the first in the industry to offer return insurance to our customers. Return insurance provides 30 days for you to try a mask and return it for any reason for a refund of the price of the mask. If you are trying a mask for the first time, return insurance might be right for you.

    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
    How can I find replacement parts for my CPAP mask?
    Replacement parts such as: mask cushions, headgear, headgear clips, and others are available for many masks.

    To find parts which are compatible with your mask, or to find which parts of your mask are replaceable, do the following:
    • Use our Replace Part Wizard to identify your mask and see all the related parts.
    • Browse for your mask and then click the "Replacement Parts" button on your mask's product page.
    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.
    Are mask cushions interchangeable with other mask frames or can I use a different size cushion on the same frame?
    The answer to this question depends on the mask. In most cases, the mask frame will only accept cushions or pillows made for that specific mask. However, there are a few variations to this rule: ResMed's Mirage SoftGel Nasal CPAP Mask and Mirage Activa LT Nasal CPAP Mask are examples of the exception. In this case, both masks use the same mask frame; therefore, the cushions for the two masks are interchangeable. The EasyFit Masks by DeVilbiss offer different cushion types such as gel or silicone, which are interchangeable between the mask frames.

    As to whether or not you can use different size cushions for a specific mask on the same mask frame, this also depends on the mask. Some mask frames are compatible with multiple cushion or pillow sizes, while other mask frames only fit cushions of the same size. This information is provided on the product pages. Please review the page of the specific product you are interested in to learn if you will need a different size mask frame for each size of cushion or pillow.
