CPAP Replacement Schedule

1. Overview

CPAP equipment works best when it is clean, well maintained and replaced at the right time. Over time, parts such as masks, silicone cushions, headgear, tubing, filters and humidifier water chambers can wear out, lose shape, collect residue or become less effective.

A regular replacement schedule can help you maintain a better seal, reduce air leaks, improve comfort and keep your therapy equipment in better condition.

3. Visual Product Guide

The parts below are the most common CPAP items that require regular replacement. This visual guide helps you quickly understand which part is which and where to find replacements.

4. CPAP Mask

Recommended replacement: every 6–12 months.

Signs of an Aging CPAP Mask

• Air leakage
• Loose or unstable fit
• General discomfort
• Frayed fabric
• Visible rips or tears in the cushion area
• Loss of cushion shape

Getting the Most Out of Your CPAP Mask

Wash your CPAP mask regularly with warm water and gentle soap or baby shampoo. Avoid harsh chemicals, alcohol-based cleaners or strong detergents unless approved by the manufacturer.

5. CPAP Mask Silicone Cushion

Recommended replacement: every 3–6 months.

Signs of an Aging Mask Silicone Cushion

• Air leakage
• Visible rips or tears
• Loss of cushion shape
• Poor seal even after cleaning or adjustment
• Need to over-tighten the mask to stop leaks

Getting the Most Out of Your Silicone Cushion

Wipe your CPAP mask silicone cushion after each use. Oils from the skin can accelerate material degradation and reduce the quality of the seal.

CPAP mask wipes can help with quick daily cleaning, especially when used as part of a regular cleaning routine.

6. CPAP Mask Headgear

Recommended replacement: every 6–9 months.

Signs of Aging CPAP Headgear

• Loose fit
• Over-stretched straps
• General discomfort
• Need to over-tighten the mask
• Frayed fabric
• Visible rips or tears

Getting the Most Out of Your Headgear

CPAP mask headgear naturally stretches over time. Adjust it so the mask feels secure but not too tight. Over-tightening can be uncomfortable and may also cause the headgear and mask parts to wear faster.

Wash headgear gently and only as recommended by the manufacturer.

7. CPAP Hoses and Tubing

Recommended replacement: every 6–12 months.

Signs of Aging CPAP Hoses and Tubing

• Air leakage
• Loose hose connections
• Visible rips or tears
• Mineral build-up
• Unfamiliar odours
• Signs of mould growth

Getting the Most Out of Your CPAP Tubing

Tubing can wear out around the edges or connection points, and even small tears can cause air leaks. Wash tubing gently and allow it to dry fully before reconnecting it to your machine.

8. CPAP Air Filter

Recommended replacement: every 3–6 months.

Signs of an Aging CPAP Air Filter

• Visible dust or dirt
• Low airflow
• Unfamiliar odours
• Filter discolouration

Getting the Most Out of Your CPAP Air Filter

CPAP filters usually last from around 90 to 180 days depending on the environment, machine model and usage. Once the filter has reached its recommended use period or appears dirty, replace it.

9. CPAP Humidifier Water Chamber

Recommended replacement: every 6–12 months.

Signs of an Aging Humidifier Water Chamber

• Heavy mineral build-up
• Discolouration of plastic
• Unfamiliar odours
• Signs of mould growth
• Difficulty cleaning the chamber properly

Getting the Most Out of Your Water Chamber

Use distilled water where possible to reduce mineral build-up. Empty and dry the water chamber daily and clean it according to the manufacturer’s instructions.

10. Cleaning Tips for Longer Product Life

Good cleaning habits can help extend the usable life of CPAP parts and improve comfort during therapy.

• Wipe the mask silicone cushion after each use.
• Wash the mask regularly with warm water and gentle soap.
• Allow tubing and humidifier parts to dry completely before use.
• Use distilled water in the humidifier chamber where possible.
• Replace disposable filters instead of washing them.
• Inspect mask parts regularly for tears, stretching or loss of shape.
