When Should I Replace My CPAP/BiPAP Supplies, Masks, and Headgear?

Using a CPAP or BiPAP machine is essential for treating sleep apnea, but replacing worn parts on time is just as important. Over time, your mask, headgear, filters, tubing, and cushions can wear out, impacting comfort, performance, and hygiene. Knowing when to replace each item keeps your therapy effective and helps prevent health issues.

Why Timely Replacement Matters

• Maintains optimal air pressure – Worn parts can cause leaks and reduce therapy effectiveness.

• Improves comfort – Fresh supplies fit better and reduce irritation.

• Promotes hygiene – Old materials can harbor bacteria, mold, and allergens.

• Prevents unexpected breakdowns – Regular replacement reduces the risk of sudden equipment failure.

Recommended Replacement Schedule

Here’s a general guide for when to replace your CPAP/BiPAP supplies. Always follow your manufacturer’s recommendations and check your insurance coverage, as many plans cover regular replacements.

• Mask Cushions/Pillows – Every 1–3 months

  • Silicone and gel cushions lose their seal over time, causing leaks.

  • Oils from your skin can break down the material.

• Full Face or Nasal Mask Frame – Every 3–6 months

  • Plastic frames can warp and lose shape.

  • Worn frames may not hold cushions securely.

• Headgear & Chin Straps – Every 6 months

  • Elastic stretches and loses tension, causing a poor fit.

  • Loose headgear can lead to leaks and discomfort.

• CPAP/BiPAP Tubing – Every 6–12 months

  • Cracks, discoloration, or mineral buildup can affect airflow.

  • Heated tubing should be checked more frequently.

• Disposable Filters – Every 2–4 weeks

  • Dust and allergens quickly clog filters, affecting air quality.

  • More frequent replacement may be needed in dusty or humid environments.

• Reusable Filters – Every 6 months (or as directed)

  • Wash regularly, but replace when they lose shape or become discolored.

• Water Chamber (Humidifier) – Every 6–12 months

  • Mineral deposits and plastic degradation can affect water purity.

Signs It’s Time to Replace Sooner

Even if you follow the schedule, you may need to replace supplies earlier if you notice:

• Persistent air leaks

• Cracks or tears in silicone or plastic

• Yellowing or discoloration

• Unpleasant odors

• Reduced therapy effectiveness

• Skin irritation or red marks that don’t go away

Tips to Extend the Life of Your Supplies

• Clean daily – Wash cushions, mask, and tubing with mild soap and warm water.

• Air dry completely – Prevents bacteria and mold growth.

• Use distilled water – Reduces mineral buildup in the humidifier.

• Avoid harsh cleaners – Strong chemicals can damage silicone and plastics.

Bottom line: Timely replacement of your CPAP/BiPAP supplies ensures effective therapy, better hygiene, and longer equipment life. If you’re unsure about your replacement schedule, check with your equipment provider or healthcare professional. Your sleep — and your health — depend on it.
