📏 Choosing the Right Size

The AirFit F40 cushion is available in Small Wide, Medium, and Large to accommodate a range of facial shapes. Choosing the correct size supports a better seal, fewer leaks, and more comfortable therapy — we recommend checking against the official ResMed sizing guide before ordering if you're unsure which size you currently use.

Small Wide Medium Large

🧼 Cleaning Instructions

Regular cleaning extends the life of your cushion and helps maintain hygiene for safe, effective therapy.

  • Remove the cushion from the mask frame before cleaning.
  • Wash daily using warm water and a mild, non-abrasive detergent.
  • Rinse thoroughly to remove all soap residue.
  • Allow to air dry away from direct sunlight before reattaching.
  • Do not use alcohol-based cleaners, bleach, or abrasive cloths, as these may damage the silicone.
  • Replace the cushion regularly, or sooner if it appears worn, discoloured, or begins to leak.

Why Choose the ResMed AirFit F40 Replacement Cushion?

A worn cushion is one of the most common causes of mask leaks and disrupted therapy — and one of the easiest to fix. As a genuine ResMed component, this AdaptiSeal™ cushion is built to the exact specification of your AirFit F40 mask, so fit, seal, and comfort are exactly as intended. Its magnet-free, no-hard-parts construction makes it a straightforward, reliable way to keep your therapy consistent night after night, whether you're replacing a worn cushion or keeping a spare on hand.

⚠ Important Safety Notice

This cushion is a component of a medical device intended for the treatment of obstructive sleep apnoea and must only be used as part of a complete, compatible ResMed AirFit F40 mask system prescribed or recommended by a qualified healthcare professional.

Always confirm cushion size and mask compatibility before use, and inspect the cushion regularly for signs of wear, damage, or discolouration. A damaged or poorly fitted cushion can reduce seal quality and therapy effectiveness.

If you experience skin irritation, persistent leaks, or any adverse reaction while using this product, discontinue use and consult your CPAP provider or healthcare professional.

Frequently Asked Questions

Q: How often should I replace my ResMed AirFit F40 cushion?
A: For the best seal and comfort, ResMed recommends replacing the AirFit F40 cushion approximately every 1–3 months, depending on usage, cleaning routine, and signs of wear.

A: No. The AirFit F40 cushion is designed specifically for the ResMed AirFit F40 Full Face CPAP Mask and is not compatible with other AirFit or AirTouch mask models.

Q: Why is my AirFit F40 cushion leaking?
A: Air leaks are often caused by a worn cushion, incorrect sizing, or an improperly adjusted headgear. Replacing the cushion and ensuring the correct fit can help restore an effective seal.
