CPAP Supply Replacement Guide: Keep Your Therapy Clean, Comfortable & Effective
CPAP Supply Replacement Guide: Keep Your Therapy Clean, Comfortable & Effective
Continuous Positive Airway Pressure (CPAP) therapy is one of the most effective treatments for sleep apnoea.
Your machine delivers a steady stream of air to keep your airway open, preventing snoring and interruptions in breathing.
But the machine alone isn’t enough—masks, cushions, filters, and tubing all need regular care and timely replacement to keep therapy comfortable and effective.
This guide outlines how often to replace each CPAP component and how to spot wear and tear,
Why a Replacement Schedule Matters
Worn or dirty CPAP supplies can lead to:
- Air leaks that reduce therapy pressure
- Skin irritation or discomfort
- Bacteria and mould growth
- Shortened equipment lifespan
Replacing parts on schedule keeps your therapy hygienic, quiet, and consistently effective.
Recommended Replacement Timeline
1. CPAP Masks – Replace Every 3 Months
The mask delivers pressurised air to your airways and must maintain a perfect seal.
Signs it’s time to replace:
- Persistent air leaks even after refitting
- Discomfort or loss of cushion flexibility
- Discolouration or cracks
💡 Tip: Full face, nasal, and nasal pillow masks all follow the same three-month replacement cycle.
2. Mask Cushions & Pillows
- Silicone cushions (e.g. ResMed AirFit™): replace every 3 months
- Memory foam cushions (e.g. ResMed AirTouch™): replace monthly
Because these soft materials break down over time, they can lose shape and fail to seal.
When to replace:
- Cracks or visible wear
- Hardening or stickiness
- Persistent leaks
3. Mask Headgear & Chin Straps – Replace Every 6 Months
Headgear keeps the mask secure, and chin straps help mouth breathers maintain a seal.
Elastic stretches over time, loosening the fit.
When to replace:
- Straps feel loose even when tightened
- You need frequent mid-night adjustments
4. CPAP Machine Filters – Replace Every 2 Weeks
Filters trap dust and allergens, protecting both you and your machine.
When to replace:
- Visible dirt or discolouration
- Reduced airflow or unusual machine noise
Regular filter changes improve air quality and extend the life of your CPAP motor.
5. CPAP Tubing – Replace Every 3 Months
The tubing carries pressurised air from machine to mask.
Over time it can develop tiny cracks, tears, or internal residue.
When to replace:
- Opaque or yellowed tubing
- Visible tears or stiffness
- Unexplained leaks or “gurgling”
6. CPAP Water Chamber – Replace Every 6 Months
Your humidifier chamber heats and moistens therapy air for comfort.
Repeated heating and cooling eventually cause mineral build-up, cracks, or leaks.
When to replace:
- Cloudiness or discolouration
- Cracks or leaking seams
7. CPAP Machine – Replace Every 3–7 Years
Your machine is the heart of therapy.
While many devices run longer, performance naturally declines with age.
When to replace:
- Frequent error codes or power failures
- Out of warranty and costly to repair
- No longer meeting therapy needs
