Compare silicone and memory foam CPAP mask cushions comfort, cleaning, replacement cost and which material suits your face and routine best.
Choosing a CPAP mask is not just about finding the right shape. The material that sits against your face can also affect how the mask feels, how you care for it and how often you need to replace its cushion. ResMed’s AirFit range uses silicone cushions, while the AirTouch F20 uses a soft memory foam cushion. Both are designed for CPAP therapy, but they feel and require different care. This guide compares the two materials using manufacturer information and the available product details.

Silicone vs Memory Foam: What Is the Difference?
AirFit F20 · Flexible seal
Flexible seals that sit against the face. Used across many CPAP mask styles. Designed to create a seal while accommodating normal movement during sleep. Require regular cleaning to remove facial oils and residue.
AirTouch F20 · UltraSoft foam
Designed to mould to the contours of the face. ResMed describes the material as soft and breathable, and says it may help reduce pressure and red marks on the skin. Individual comfort and fit will vary. Wipe-care only do not soak or wash.
The main difference is not that one material works for everyone and the other does not. It is how each cushion feels against your skin, how it fits your face and how you prefer to maintain it.

💡 Modular F20 frame system. ResMed confirms that the AirFit F20 and AirTouch F20 share a modular design, allowing their cushions to be interchanged with the compatible F20 frame. Always check the exact model and instructions before changing parts.
The four dimensions that matter most when comparing the two materials: comfort against the face, daily cleaning requirements, replacement cadence, and the flexibility to switch between materials on the same F20 frame system.
Five Areas of Comparison
1
Comfort and the Feel Against Your Skin
Silicone: flexible, familiar Memory foam: conforms to contours Individual experience varies
The AirFit F20’s silicone cushion is flexible and designed to accommodate different facial profiles. Some users may prefer the familiar feel of silicone, while others may prefer a softer material against the face. The AirTouch F20’s memory foam cushion is designed to adapt to facial contours. ResMed says the foam can reduce friction and contact pressure, which may help reduce visible marks for some users. That does not mean it will eliminate marks or leaks for everyone. If you often notice pressure or marks around the area where your cushion rests, the foam option may be worth discussing with your equipment provider. Fit, mask size, strap tension and sleeping position can also affect comfort.
2
Cleaning and Daily Care
Silicone: wash regularly Foam: wipe only never soak or wash
Cleaning is one of the practical differences between these cushions. Silicone cushions need regular cleaning to remove facial oils, dirt and residue. Follow the instructions supplied with your mask and use suitable cleaning products. The AirTouch memory foam cushion has different care requirements. ResMed advises that it should not be immersed in water. If cleaning is needed, wipe it with a suitable CPAP wipe or equivalent and allow it to dry as directed. The frame, elbow and headgear have their own cleaning instructions, so do not treat the whole mask as if it were made from foam. Do not soak or wash the memory foam cushion in the same way you might clean a silicone cushion. Check the user guide for your exact mask model.
3
Cushion Replacement and Ongoing Cost
AirTouch foam: generally monthly Silicone: replace when worn or damaged Factor replacement cushion cost into total
A mask’s purchase price is only part of its cost. You should also consider how often its cushion needs replacing and how much replacement parts cost. ResMed recommends regular replacement of AirTouch foam cushions, generally on a monthly schedule. The silicone cushion also needs to be inspected and replaced when worn, damaged or no longer providing a suitable fit. Replacement timing can depend on the mask, usage and supplier guidance. Before choosing, compare the cost of the complete mask and its replacement cushions not just the initial price.
4
Fit and Air Leaks
No material guarantees a leak-free fit Correct size and positioning essential for both Don’t overtighten headgear to fix leaks
Neither silicone nor memory foam guarantees a leak-free fit. The seal depends on choosing the correct size, positioning the mask properly and adjusting the headgear without overtightening it. The AirFit F20 uses ResMed’s InfinitySeal silicone cushion. The AirTouch F20 uses a memory foam cushion designed to conform to facial contours. Both are full-face masks covering the nose and mouth, but the way the cushion contacts your face differs. If your mask leaks, check its position and size and inspect the cushion for wear. Tightening the straps too much can make the mask uncomfortable and may not solve the problem. If leaks continue, ask your CPAP provider for help with fitting.
5
Can You Switch Between AirFit and AirTouch?
✓ F20 frame is modular ✓ Cushions interchangeable with the same F20 frame Check components and instructions before switching
For the F20 range, ResMed designed the masks so the compatible silicone and memory foam cushions can be used with the same F20 frame. This means some users may be able to try the other cushion material without changing the entire mask system. Check that you have the correct F20 components and follow the manufacturer’s fitting instructions. Compatibility should not be assumed across different mask families or models.
The F20 frame is shared between both masks, meaning users can switch between the silicone and memory foam cushion without replacing the entire mask system. Always confirm you have the correct F20 components and follow the manufacturer’s fitting instructions before swapping cushions.
Which Should You Consider?
AirFit F20 may suit you if…
- You prefer a silicone cushion
- You are comfortable with regular cushion cleaning
- You want to compare the silicone option with the available memory foam cushion

AirTouch F20 may be worth considering if…
- You want to try a softer memory foam cushion

- You would prefer the foam cushion’s specific wipe-care routine
- You are prepared to follow its replacement and maintenance guidance
These are points to consider, not guarantees. Mask comfort is personal, and a suitable fit is essential whichever material you choose.

Frequently Asked Questions
Is silicone or memory foam better for CPAP masks?
Neither material is best for everyone. Silicone is flexible and requires regular cleaning. Memory foam is designed to mould to facial contours and has different care and replacement requirements. Your fit and comfort matter more than the material name alone.
Is the ResMed AirTouch F20 made from memory foam?
Yes. The AirTouch F20 uses ResMed’s UltraSoft memory foam cushion. It is a full-face mask covering the nose and mouth.
Is the ResMed AirFit F20 made from silicone?
Yes. The AirFit F20 uses a silicone InfinitySeal cushion.
Can I use an AirTouch F20 cushion on an AirFit F20 frame?
ResMed states that the F20 system is modular and that the AirFit F20 and AirTouch F20 cushions are interchangeable with the compatible F20 frame. Check your specific components and user guide before switching.
How do I clean an AirTouch memory foam cushion?
Do not soak or immerse the foam cushion in water. ResMed advises wiping it with a suitable CPAP wipe or equivalent when needed and allowing it to dry as directed. Follow the instructions for your particular mask.
How often should I replace an AirTouch F20 cushion?
ResMed recommends regular replacement of the AirTouch F20 foam cushion, generally monthly. Check the manufacturer’s guidance and inspect the cushion for wear or damage.
Will memory foam stop my mask from leaking?
No cushion material can guarantee that. Leaks can result from incorrect sizing, positioning, strap adjustment, movement or worn parts. If leaks persist, seek help with fitting rather than relying on tighter straps alone.
Final Thoughts
The choice between silicone and memory foam comes down to comfort, fit and the care routine you can maintain. The ResMed AirFit F20 uses a silicone cushion, while the AirTouch F20 uses a memory foam cushion designed to adapt to facial contours. Their compatible F20 frame system also gives users the option of switching between cushion types when the components and instructions allow it.
Before choosing, check the mask size, cushion replacement guidance and total cost of ownership. If you are unsure which mask is suitable for your therapy, speak to your CPAP provider or healthcare professional.
