ResMed AirFit F40 Replacement Cushion — Overview
The ResMed AirFit F40 Replacement Cushion is the genuine soft silicone cushion for the AirFit F40 full face mask — the same cushion supplied with a new mask, sold separately for routine replacement. The F40's cushion uses an under-the-nose design that seals below the nostrils rather than across the nasal bridge, with a soft, flexible silicone that adapts to facial contours to reduce pressure points and deliver a comfortable, secure seal.
Replacing the cushion every 3 months restores the AirFit F40's original seal quality. Daily use causes the silicone to soften and degrade — skin oils, heat, and repeated compression break down the sealing surface over time, leading to increased leaks and reduced comfort. A genuine replacement cushion takes minutes to swap and immediately refreshes therapy performance.

When to Replace Your F40 Cushion
- It has been 3 months since the last cushion replacement
- You notice increased leaks that weren't present when the mask was newer
- The silicone feels harder or less flexible than when new
- Visible discolouration, cracking, or surface breakdown is present
- Your machine's reported leak rate has increased over recent sessions
🧼 Daily care extends cushion life: Wash the silicone cushion daily with mild soap and warm water — rinse thoroughly and air dry away from direct sunlight. Avoid alcohol wipes or harsh detergents on silicone, which accelerate surface degradation. Store the mask cushion-side up or hanging to prevent compression of the sealing surface when not in use.

Common Questions
Is this cushion compatible with any other ResMed full face mask?
No — the AirFit F40 cushion is exclusively designed for the AirFit F40 mask and is not interchangeable with cushions from the F20, F30, or F30i. Each ResMed full face mask uses its own specific cushion system. If you own a different mask, contact our team via WhatsApp on +971 56 593 5931 to confirm the correct replacement cushion.
How often should I replace the F40 cushion?
Every 3 months with daily proper cleaning. Daily washing with mild soap and warm water helps maintain hygiene and extend cushion life. If you notice increased leaks, hardening of the silicone, or visible wear before the 3-month mark, replace sooner — a fresh cushion immediately restores seal performance.
Which size should I order?
Order the same size as your current AirFit F40 cushion. The size is printed on the cushion itself or can be found in your original mask packaging. If you're unsure, Medium fits most patients. Contact our team via WhatsApp on +971 56 593 5931 with your mask details and we can confirm the correct size.
