CPAP Supplies
CPAP supplies, also called CPAP replacement parts or sleep apnea supplies, are the wear-and-replace parts and equipment that keep your therapy working night after night: mask cushions and nasal pillows, headgear and clips, mask frames, filters, tubing and heated tubing, and humidifier water chambers. We carry replacements for the major CPAP brands, so you can swap a worn part fast and stay on a regular replacement schedule. Looking for add-ons like travel cases, comfort items, or power instead? Those live in CPAP accessories.
Shop CPAP supplies by part type
- Cushions and pillows: the part that seals against your face and wears out the fastest. Replace it when the seal softens or starts to leak.
- Headgear and headgear clips: the straps that hold your mask in place. Replace them when they lose tension.
- Mask frames: the body of the mask that connects your cushion, elbow, and headgear.
- Filters: keep dust and particles out of your machine. Disposable filters are replaced more often than reusable ones.
- Hoses and tubing: standard and heated tubing options for major machines.
- Humidifier and water chamber: replacement chambers and humidifier parts.
- Distilled water: for your humidifier reservoir.
- Cleaning supplies: wipes, brushes, and sanitizing products to keep your parts hygienic.
Not sure what is leaking or feeling off? Start here
- Mask leaking or fitting differently: start with a replacement cushion or nasal pillow, then check headgear stretch and the frame connection.
- Airflow feels weak or the machine sounds louder: check filters first, then inspect your tubing for wear or small leaks.
- Dry or harsh air, or rainout in the hose: look at heated tubing and your humidifier chamber, and confirm your machine supports them.
- Packing for a trip: bring compact filters and tubing for your travel machine, plus the accessories that make travel easier.
CPAP replacement schedule
How often you replace a part depends on the item and how it wears, and your insurer may follow a set resupply schedule. As a general guide, cushions and nasal pillows wear fastest and are replaced most often, disposable filters go on a regular cycle (more often than reusable filters), tubing is replaced periodically, and headgear and frames are replaced when they lose tension or stop sealing. Water chambers are replaced periodically too. Swapping worn parts on time helps your mask seal and keeps your setup hygienic. For a fuller breakdown, see how often to change your CPAP supplies. Because these parts wear on a set cycle, you can Subscribe & Save to have replacements arrive automatically and never run out.
Find supplies for your machine or mask
If you know your equipment, the fastest path is to match the part to your exact model. Browse parts for your device in CPAP machines or match your mask in CPAP masks. We carry supplies for the major brands, including ResMed, Philips Respironics, and Fisher and Paykel. Parts rarely cross between different mask styles, so confirm the listing names your model before you buy.
Prescription, insurance, and FSA or HSA
In the United States, a CPAP machine and a complete mask system generally require a prescription, while many replacement parts such as cushions, headgear, and filters are sold without one. CPAP supplies are commonly FSA and HSA eligible as medical expenses, so you can often use pre-tax funds; keep your itemized receipt for your records. If you have questions about what your plan covers through insurance or Medicare, check with your provider.
