If your CPAP therapy is feeling less effective lately — maybe your mask is leaking, or your machine sounds louder — your equipment might be trying to tell you something:🕒 It’s time to replace your CPAP parts.
Regular replacement keeps your therapy clean, effective, and comfortable — and it can make a huge difference in your sleep quality.
Let’s break down how often to replace each CPAP part, why it matters, and where to get genuine ResMed parts in South Africa.
🛏️ 1. CPAP Mask Cushions — Every 3 to 6 Months
Your mask cushion is the soft silicone part that seals against your face. Over time, oils from your skin cause it to lose elasticity and grip, leading to leaks and discomfort.
🧼 Even with daily cleaning, small cracks and residue build up — making your therapy less effective.
Replace every:
3 months (if used daily)
6 months (for light use)
✅ Tip: ResMed AirFit series cushions (F20, N20, P10, F40) are available separately, so you don’t need to buy a whole new mask.

🌬️ 2. CPAP Filters — Every 1 to 2 Months
Think of your CPAP filter as your machine’s lungs. It traps dust, pollen, and fine particles from the air.
When it clogs, your machine works harder and your air quality drops.That’s bad news for your therapy and your health.
Replace every:
1 month (in dusty or pet-filled environments)
2 months (in clean indoor air)
✅ Tip: Use hypoallergenic filters if you’re sensitive to dust or pollen.

💧 3. Humidifier Tub (Water Chamber) — Every 6 Months
Your humidifier keeps your airway moist, but over time mineral deposits and bacteria build up — especially if you use tap water.
Even after cleaning, small cracks can form, making it impossible to maintain hygiene.
Replace every:
6 months (or sooner if cloudy or cracked)
✅ Tip: Always use distilled water to extend lifespan.
🌡️ 4. CPAP Tubing — Every 6 to 12 Months
Your tubing delivers the pressurised air — but it also collects moisture and bacteria over time.
If you notice a musty smell or visible condensation, it’s time for a new one.
Replace every:
6 months (standard tubing)
12 months (heated ClimateLineAir tubing)
✅ Tip: Hang tubing daily to air dry after each use.
💤 5. Headgear and Straps — Every 6 to 12 Months
Elastic stretches with use and washing.When your straps start slipping or you need to overtighten to prevent leaks — it’s time to replace them.
Worn-out headgear can compromise your seal and reduce comfort.
Replace every:
6 months for daily users
⚙️ 6. CPAP Machine Filter Cover and Accessories — As Needed
These aren’t replaced as often, but inspect them regularly. Cracks, discoloration, or loose fittings can all affect performance.
✅ Always choose genuine ResMed parts — third-party components can alter pressure accuracy and void your warranty.
🧼 BONUS: Daily Cleaning Tips to Extend Lifespan
Wash mask cushion daily with mild soap and water (no alcohol or harsh detergents)
Rinse tubing weekly
Empty humidifier daily and refill with fresh distilled water
Wipe down machine exterior with a dry cloth
Store everything away from direct sunlight
