    Common CPAP Supplies Questions

    CPAP parts, also known as CPAP supplies, are parts of the CPAP machine and mask that need to be replaced regularly in order to maintain optimal air quality. CPAP parts, like any machine parts, need to be replaced every so often due to use, wear, and tear. Unlike parts for your car, which are often available locally, the widest selection of parts and supplies is available online.

    Here's a list of the most common supplies that you'll need when you own a CPAP device:

    Disposable Filters

    Disposable filters are designed to filter the air (much like the air filter in your car or house) and keep mold, dust, and other irritants out of the therapy air you breathe. Disposable filters come in different styles and sizes (depending on the kind of machine you have) and are relatively inexpensive.

    Reusable Filters

    Reusable filters are made of foam and are washable, and reusable to a point. Eventually, the foam will begin to break down, and the reusable filter will need to be replaced. Many machines use both disposable and reusable filters, and you typically can't replace disposable filters with reusable filters. Reusable filters are also fairly inexpensive.

    Bacteria Filters

    Bacteria filters are optional and can be attached at the end of the hose near where it connects to the mask (it can also connect between the machine and the hose in some machines). It's designed to catch even the smallest bacteria, allergens, and pollutants that other filters miss. A bacteria filter is disposable and is fairly inexpensive. They can be purchased one at a time or in packs of five or more. Bacteria filters should be replaced every 30 days, or sooner if it starts to look discolored.

    CPAP Hoses and Tubing

    CPAP hoses and tubing are the connection from the machine to the CPAP mask and are usually made of stiff plastic. Hoses are typically 19mm wide with 22mm ends, and most are 6 feet long. So-called "slim" hoses are gaining in popularity and are typically 15mm wide, 4mm smaller than standard hoses. Some hoses can be heated to add comfort (as this can eliminate the formation of condensation inside the hose which can cause water to hit the nose or face). Most are fairly inexpensive.

    CPAP Machine Parts

    CPAP machine parts include things like power supplies, electrical cords, replacement covers for damaged shell parts, and can widely vary in price.

    CPAP Humidifier Parts

    The most common of these items are replacement humidifier chambers. The humidifier chamber is the container that holds distilled water for humidification of CPAP air. Some manufacturers make dishwasher-safe humidifier chambers, available as an optional upgrade, and many of our customers order these items. Replacement humidifier chambers can cost $50 or less.

    • Filters: Disposable filters are typically made of paper and should be replaced once every 4 weeks. Reusable filters should be washed regularly and replaced every 6 months (or sooner if the filter starts to deteriorate). Bacteria filters are optional for most CPAP configurations and are designed to keep out any bacteria or other irritants that other filters miss, and should be replaced after 30 days (or sooner if discolored)
    • CPAP Hoses and Tubing: Hoses should be washed regularly, and replaced every 6-12 months.
    • CPAP Machine Parts: CPAP machine parts should be replaced when broken
    • CPAP Humidifier Parts: CPAP humidifier parts (like chambers) should be replaced every 6-12 months, or sooner if discolored or displaying signs of deposit buildup.

    If you aren't following a good replacement schedule for the parts on your machine, the quality of the air you breathe will go down. This means you could have greater exposure to infections, mold, colds, and other harmful bacteria. Following a good replacement schedule will help keep you healthy, and it may also mean your machine lasts longer too. Ordering replacement parts can be done almost automatically, and they'll be delivered right to your door. It's low-cost and convenient.

    Some parts, like disposable filters, don't need to be disinfected. Other parts, like hoses and masks, should be disinfected using scent-free mild soap and water. It's never recommended to use household cleaners, bleach, or other harsh cleaners to disinfect parts and supplies. Harsh chemicals can leave a residue that pollutes the air you breathe, causing it to become toxic.
