How Often Should You Replace Your CPAP Mask, Cushion & Headgear?
Your CPAP equipment works hard every night. Replacing it on schedule is the simplest way to maintain comfort, prevent leaks, and keep your therapy performing at its best.
Updated June 20267 min readEquipment Maintenance
The simple version: Cushions every 1–3 months, headgear every 6 months, the elbow every 6–12 months, and the mask frame every 12 months. Replacing components on this schedule — rather than waiting until they fail — is the single easiest way to protect your therapy quality night after night.
Your CPAP equipment works hard every night to help you breathe comfortably and get the restful sleep you need. However, even the best CPAP masks and accessories wear out over time. Replacing components at the right intervals helps maintain a proper seal, improves comfort, and ensures your therapy remains effective.
If you're using a ResMed AirFit F20 full face mask or similar CPAP equipment, here is exactly what you need to know about replacement schedules — and the warning signs that tell you it's time sooner.
Why It Matters
Why Regular Replacement Matters
Over time, CPAP components gradually lose the properties that made them effective when new. Worn-out equipment doesn't just become less comfortable — it actively undermines the effectiveness of your therapy.
⏳ What Happens Over Time
Components become less effective at sealing
Materials stretch or wear down with use
Parts become more difficult to clean properly
Overall comfort declines gradually
⚠ The Consequences
CPAP mask leaks during the night
Reduced therapy effectiveness
Skin irritation from poor-fitting parts
Increased noise and poor sleep quality
Replacement Schedule
Component-by-Component Replacement Guide
Each part of your CPAP mask wears at a different rate. Here is exactly how often to replace each one — and the specific signs to watch for between scheduled replacements.
💧
CPAP Mask Cushion
Every 1–3 Months
Your cushion is the part that makes direct contact with your face and experiences the most wear of any component. Many users choose either the AirFit F20 silicone cushion or the softer AirTouch F20 cushion, depending on their comfort preferences.
Signs It's Time to Replace
Visible wear or tears in the silicone
Increased air leaks during the night
Loss of flexibility or shape
Discomfort around the nose or mouth
Difficulty maintaining a consistent seal
Discolouration despite regular cleaning
🎯
CPAP Headgear
Every 6 Months
The F20 mask headgear gradually stretches with nightly use. Even with careful adjustment, elastic straps eventually lose the tension needed to keep your mask properly positioned and sealed throughout the night.
Signs It's Time to Replace
Loose fit despite tightening adjustments
Reduced stability during sleep
Increased mask movement overnight
Visible loss of elasticity in the straps
🛡️
CPAP Mask Frame
Every 12 Months
The mask frame is more durable than cushions and headgear but should still be inspected regularly. The ResMed AirFit F20 frame is designed for long-lasting performance when properly maintained, but it isn't built to last indefinitely.
Replace Sooner If You Notice
Visible cracks or structural damage
Loose connections to the cushion or elbow
Reduced overall mask stability
🔧
CPAP Elbow Connector
Every 6–12 Months
The elbow connector is an important part of the mask system that joins the tubing to the mask itself, and it can wear over time through repeated connection and removal during cleaning and daily use.
Signs You Need an Elbow Replacement
Noisy airflow around the connection point
Loose connections to tubing or mask
Visible cracking or damage
Reduced overall mask performance
⚠ Signs Your CPAP Equipment Needs Replacing — Regardless of Schedule
›Frequent mask leaks during the night
›Waking up tired despite consistent CPAP use
›Increased noise from the mask or connections
›Discomfort or pressure marks on your face
›Worn straps or flattened, aged cushions
›Difficulty achieving or maintaining a proper seal

Good daily habits can meaningfully extend the working life of each component — helping you get the most value from every replacement part.

Clean your mask daily with mild soap and warm water
✓
Wash headgear regularly according to manufacturer guidelines
✓
Replace worn cushions promptly rather than pushing past their lifespan
✓
Store equipment away from direct sunlight when not in use
✓
Inspect all components weekly for early signs of wear and tear
✓
Use genuine replacement parts designed for your specific mask model
💡
Good maintenance maximises comfort and effectiveness
Daily care doesn't replace the need for scheduled component replacement — but it does help each part perform at its best for the full length of its intended lifespan, and can help you catch early warning signs before they affect your sleep.

Most Replaced
Cushion
ResMed AirFit / AirTouch F20 Cushions
Genuine silicone and memory foam replacement cushions for the F20 frame. Available in small, medium, and large. Replace every 1–3 months for a reliable seal.
Most CPAP cushions should be replaced every one to three months, depending on wear and frequency of use. Daily cleaning helps extend this lifespan slightly, but the silicone or foam will still degrade over time — even if it looks visually intact. If you notice increased leaks, discomfort, or a cushion that feels less flexible than when new, replace it regardless of how long you have had it.
The F20 mask headgear typically lasts around six months before losing meaningful elasticity. Elastic straps stretch gradually with nightly use, and once they lose their tension, no amount of tightening will fully restore a stable, secure fit. If your mask feels loose or shifts position during the night despite adjustment, it's a strong sign your headgear needs replacing.
Worn CPAP parts can cause a range of problems — air leaks that reduce the pressure actually reaching your airway, discomfort and skin irritation from degraded materials, reduced overall therapy effectiveness, and poor sleep quality as a result. In many cases, these issues develop gradually, so users don't always notice the decline until they replace the worn part and feel the difference immediately.
Yes. Genuine replacement parts are engineered specifically to maintain the fit, comfort, and seal performance of your CPAP therapy system. Generic or third-party parts may not match the precise geometry of the original components, which can compromise the seal in ways that aren't always obvious — even though the part appears to fit. Using genuine parts helps ensure your therapy continues working exactly as your clinician intended.
A combination of both approaches works best. Use the recommended schedule as a baseline — cushion every 1–3 months, headgear every 6 months, and so on — but don't wait for the calendar if you notice clear signs of wear, such as leaks, discomfort, or visible damage. Equipment that is used more frequently or cleaned less consistently may need replacing sooner than the standard schedule suggests.
