CPAP Mask Lifespan - When to Replace Parts? 2025

CPAP Mask Part Lifespan - When Should You Replace Them?

CPAP mask parts don't last forever. Silicone degrades from skin oils, heat and repeated washing. A worn cushion creates leaks that directly undermine your therapy. Knowing when to replace parts is essential for maintaining effective treatment.

VivaRespire stocks CPAP replacement parts for the main ResMed masks. Order online with fast European delivery.

Recommended Lifespan by Part

Part Indicative lifespan Replacement frequency
Cushion / seal (silicone) 3 to 6 months Every quarter recommended
Mask frame 6 to 12 months 1 to 2 times per year

Foam filter (washable) 6 months Annual replacement or as needed

The Silicone Cushion: The Most Critical Part

The cushion degrades fastest because it contacts your skin directly. Natural oils soften the silicone progressively until it loses its seal.

Signs your cushion needs replacing

  • Persistent leaks despite correct tightening and a clean face
  • Sticky or tacky silicone even after washing
  • Discolouration: yellowing or browning of white silicone
  • Visible deformation: cracks, bubbles or permanent creases
  • Persistent odour that does not disappear after cleaning
  • Red marks or irritation on the face upon waking

How Leaks Affect Your Therapy

  • Lower effective pressure: air escapes before reaching your airway at the correct pressure.
  • Automatic pressure increase: APAP devices compensate for leaks by raising pressure, which can be uncomfortable.
  • Higher residual AHI: more residual apnea events, poorer sleep quality.
  • Sleep disruption: leak noise wakes the patient and partner.
  • Eye dryness: leaks directed towards the eyes cause irritation.
Practical rule: If your myAir score drops for no apparent reason, first check your cushion. A replacement costing €39-49 is often all that's needed to restore optimal therapy.

Headgear: Often Overlooked

Headgear straps stretch gradually with use. Slack headgear no longer holds the mask firmly in place, promoting leaks - especially when changing position during the night.

CPAP Filters

  • White disposable filter (AirSense 10 and 11): replace every 2-4 weeks. Available: AirSense 10 filters and AirSense 11 filters.
  • Grey foam filter (washable): rinse with water every 2 weeks, replace every 6 months.
