ResMed AirFit™ F20 Replacement Cushion

📦 What's Included

  • 1 × ResMed AirFit™ F20 Cushion (size as selected)

Genuine full face CPAP cushion with InfinitySeal™ technology — for the AirFit F20, F20 For Her and AirTouch F20 frames

ResMed AirFit F20 replacement silicone cushion for full face CPAP mask

The ResMed AirFit™ F20 Cushion is designed to provide a comfortable and dependable seal for your full face CPAP mask. Its flexible silicone construction adapts to facial contours, supporting a secure seal throughout the night while keeping therapy pressure where it belongs.

The cushion is the part of your mask that does the sealing, and it's also the part that wears out first. Silicone softens and stretches with nightly use, facial oils and washing, and once it loses its shape the seal starts to break — usually showing up as air hissing past your cheeks, water in your eyes, a mask you keep tightening, or leak figures creeping up on your machine. Replacing the cushion restores the fit without replacing the whole mask.

Fits: ResMed AirFit F20, AirFit F20 For Her and AirTouch F20 frames — the F20 family shares the same frame, so silicone and memory foam cushions are interchangeable. Not compatible with F30i, F40, N20 or other mask families. Please confirm your frame model before ordering.
InfinitySeal™ Cushion Design
Delivers a secure, adaptable fit that accommodates facial movement while keeping the mask stable throughout the night.
Restores the Original Seal
A fresh cushion is the single most effective fix for a mask that has started leaking — far cheaper and quicker than replacing the whole system.
Soft Medical-Grade Silicone
Flexible silicone adapts naturally to facial contours for comfort without over-tightening the headgear.
Fits the Whole F20 Family
Works with the AirFit F20, F20 For Her and AirTouch F20 frames, so you can switch between silicone and memory foam on the same mask.

F20 Family Compatible — Fits the AirFit F20, AirFit F20 For Her and AirTouch F20 frames.
✓
Soft, Flexible Silicone — Medical-grade silicone enhances comfort while adapting naturally to facial contours.
✓
Lightweight & Durable — Light on the face without compromising on seal quality or longevity.
✓
Tool-Free Fitting — Snaps on and off the frame in seconds for quick cleaning and routine swaps.
✓
Fully Washable — Unlike the AirTouch memory foam cushion, this silicone cushion can be washed in warm soapy water.
✓
Three Sizes Available — Small, Medium and Large, so you can match your original fit or re-size as needed.
✓
No Magnets in the Cushion — The cushion itself contains no magnetic components; magnetic clips sit in the F20 headgear.*

Cheaper Than a New Mask — Keeps your existing frame and headgear in service and extends the life of your mask system.

*The cushion contains no magnets. The AirFit F20 and AirTouch F20 headgear use magnetic clips, so if you have a contraindication to magnet exposure, see the magnet safety notice below — it applies to the mask system, not to this cushion.

📏 Choosing the Right Size

All three sizes fit the same F20 frame, so changing size never means buying a new mask — only a new cushion.

Small Medium Large
  • Replacing a worn cushion? Order the size printed on the one you're taking off
  • Silicone and memory foam F20 cushions share the same sizing, so an AirTouch size carries straight across
  • New to the F20? Use the printable fitting template in the documents section — it's the metric (mm) version, correct for UK use
  • Print the template at 100% scale, with page scaling switched off, or the size will be wrong
  • Measure with a relaxed jaw and a neutral expression, not a clenched one
  • If you sit between two sizes, the smaller cushion usually seals better — a cushion that's too large needs over-tightening to hold

Compatibility

  • ResMed AirFit™ F20 Full Face Mask
  • ResMed AirFit™ F20 For Her Full Face Mask
  • ResMed AirTouch™ F20 frame — the F20 family shares one frame platform
  • ResMed AirFit™ F30i / AirFit™ F30
  • ResMed AirFit™ F40
  • ResMed AirFit™ N20 / AirTouch™ N20 (nasal)
  • ResMed AirFit™ N30i / P30i / P10
  • Philips, BMC, Fisher & Paykel and other non-ResMed mask systems

Cushions are not interchangeable between ResMed mask families — each is moulded to a specific frame. Check the model printed on your frame before ordering.

🔧 Complete the Refresh

The cushion wears fastest, but it isn't the only part on a schedule. If your mask has started leaking and a new cushion hasn't fully fixed it, stretched headgear is usually the culprit.

🧼 Care & Maintenance

This silicone cushion is fully washable — unlike the AirTouch F20 memory foam cushion, which must never be submerged.

  • Detach the cushion from the frame daily and wash it in warm water with a mild, unscented soap.
  • Rub the sealing membrane gently between your fingers to lift facial oils, which are what make silicone go slack.
  • Rinse thoroughly — soap residue left on the cushion causes skin irritation and shortens its life.
  • Do not use alcohol, antibacterial gels, bleach, scented soaps, moisturising hand washes or dishwasher cycles.
  • Air dry away from direct sunlight; UV degrades silicone and hardens the sealing edge.
  • Wash your face before bed and skip night-time moisturiser — facial oils are the main cause of early cushion failure.
  • Inspect weekly for cracking, stiffening, discolouration or a sealing edge that has lost its spring.
  • Replace every 1–3 months, or sooner if the seal is compromised.

Why Choose the Genuine AirFit F20 Cushion?

Using a genuine ResMed replacement cushion helps preserve the seal quality and therapy performance your F20 mask was designed for. Off-brand or worn-out cushions can compromise your seal, leading to air leaks and reduced therapy effectiveness. Replacing your cushion on a regular schedule is one of the simplest ways to keep your CPAP therapy comfortable, hygienic and consistent night after night.

  • Air is escaping past your cheeks or blowing into your eyes
  • You're tightening the headgear more than you used to, just to hold a seal
  • Leak figures on your machine have crept up over recent weeks
  • The sealing edge feels slack, sticky, stiff or has gone cloudy
  • You're waking with red marks that weren't there a few months ago
  • It's simply been 1–3 months since the last change
  • You want a spare in the drawer so a split cushion never costs you a night of therapy

Frequently Asked Questions

Is the AirFit F20 Cushion compatible with the AirFit F20 For Her mask?
Yes. This cushion is compatible with both the standard AirFit F20 and the AirFit F20 For Her full face mask systems, since both use the same frame and cushion size range.
Will it fit my AirTouch F20?
Yes — the F20 family shares one frame platform, so this silicone cushion fits the AirTouch F20 frame and the AirTouch memory foam cushion fits the AirFit F20 frame. Many users keep one of each and switch depending on how their skin is doing.
How often should I replace my AirFit F20 cushion?
ResMed recommends replacing the cushion every 1–3 months depending on daily use and cleaning habits, or sooner if you notice cracking, discolouration or reduced seal quality.
How do I know which cushion size to order?
Check the size marking on your current cushion (Small, Medium or Large). If you're unsure, print the metric fitting template from the documents section at 100% scale, or speak with your CPAP equipment provider.
How can I tell the cushion is worn rather than the wrong size?
A worn cushion used to seal and no longer does — the leak has appeared gradually and you've been tightening the straps to compensate. A wrong-size cushion never sealed properly from the first night, no matter how it was adjusted. If it worked before and doesn't now, it's wear.
Can I use this cushion with other ResMed mask models?
No. This cushion is moulded for the F20 frame platform and is not interchangeable with other ResMed mask families such as the F30i, F40 or N20.
Can I wash it, or is it wipe-only like the AirTouch?
This silicone cushion is fully washable in warm soapy water. Only the AirTouch F20 memory foam cushion is wipe-only — washing that one destroys the foam, so it's worth knowing which you have.

⚠ Magnet Safety Notice — Applies to the Mask System

This cushion contains no magnets. However, the AirFit F20 and AirTouch F20 headgear use magnetic clips, which may interfere with certain implanted medical devices or metallic implants — including pacemakers, neurostimulators, metallic haemostatic clips in the head and metallic splinters in the eye. This is not a complete list.

ResMed produces a non-magnetic (NM) version of the F20 for users with contraindications to magnet exposure. If you have any implanted medical device, read the magnet contraindications document below and consult your healthcare provider before using the mask system.

⚠ Important Safety Notice

This cushion is a component of a medical device used for the treatment of obstructive sleep apnoea and related respiratory conditions under the direction of a qualified healthcare professional. Confirm this cushion matches your exact frame model and size before use — an incorrect fit can reduce seal quality and therapy effectiveness.

Inspect the cushion regularly for cracking, stiffening or discolouration and replace it if the seal is compromised. Never block or modify the mask vent. Please consult your clinician or CPAP supplier if you are unsure which cushion or size is right for your prescribed therapy.
