Why CPAP Mask Cushions Wear Out So Quickly
Your CPAP cushion forms the seal between your mask and your face.
Over time, several factors degrade it:
Facial oils break down the silicone
Even if you clean your mask daily, oils from the skin cause micro-tears and softening.Cushion loses shape and elasticity
Silicone becomes less flexible, causing leaks.
Pressure + moisture = faster breakdown
CPAP therapy involves continuous airflow, humidity, and overnight pressure.
Cleaning chemicals can damage silicone
Even mild soaps can shorten cushion lifespan.
This is why cushions collapse or start leaking after a few weeks.

Medicare and most private insurance follow these replacement guidelines:
Bottom line:
👉 Replace your cushion every month for the best comfort and performance.
Signs Your CPAP Cushion Needs Replacing
Even if it hasn’t been 30 days yet, replace it if you notice:
✔ Air leaks you didn’t have before
The most common symptom.
✔ Red marks or skin irritation
Often caused by over-tightening due to a worn cushion.
✔ Mask slipping during sleep
✔ A “fluttering” noise or pressure changes
✔ Cushion looks cloudy, stretched, torn, or sticky
✔ You’re waking up unrefreshed again
How Insurance & Medicare Cover CPAP Cushions
✔ Medicare covers 1 new cushion every 30 days.
No limit as long as the replacement is medically necessary.
✔ Most private insurers follow the same schedule.
Aetna, Humana, BCBS, UHC all mirror Medicare frequency.
✔ No prescription refill required for cushions.
Only the initial CPAP prescription is needed.
iSleepBetter.com began accepting Medicare last January 2025 and will process replacement cushion orders automatically.
