Premium CPAP Replacement Cushion for a Secure, Comfortable Fit

A ResLab silicone replacement cushion designed for compatibility with the ResMed AirFit™ F20 and AirFit™ F20 For Her full face CPAP masks. Made from medical-grade silicone, it adapts to a wide range of facial shapes to create a secure seal and help reduce air leaks, so your machine can deliver consistent therapy throughout the night.
The cushion is the only part of your mask that touches your face all night, and it's 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 down — air hissing past your cheeks, water running into your eyes, a mask you keep tightening, or leak figures creeping up on your machine.
Replacing the cushion restores the seal and the comfort for a fraction of the cost of a new mask. Your frame, headgear and strap settings all stay as they are — only the sealing part is renewed.

The cushion is identical in all four — only the quantity and the cost per cushion change. Start with a single if there's any doubt about your size, then move up once you know what fits.
Choose this if you're new to the F20 or not certain of your size. Confirm the fit on one before committing to a pack.
Choose this if you know your size and want a spare on hand without stocking up — two replacement cycles covered.
Choose this if you're settled on your size and want a few cycles covered without buying a year ahead.
Choose this if you're a long-term F20 user, certain of your size and staying with silicone — the lowest cost per cushion and over a year of cover.
See all F20 cushions — silicone and memory foam, singles and multipacks.
All three sizes fit the same F20 frame, so changing size later never means buying a new mask — only a new cushion. That's exactly why a single is the right first purchase.
Both fit the same F20 frame, so you can switch freely. They suit different people, and they are cared for completely differently.
Cushions are not interchangeable between ResMed mask families — each is moulded to a specific frame. Check the model printed on your frame before ordering, and if you're unsure, ask us first.
A fresh cushion seals with far less tension than the worn one you're taking off, so your current strap settings will be too tight. Over-tightening a new cushion is the fastest way to wear it out early.
The cushion wears fastest, but it isn't the only part with a schedule. If your mask is more than six months old, the cushion may not be the only thing causing the leak.
Regular cleaning extends the life of your cushion and helps maintain hygiene for safe, effective therapy. Silicone is fully washable — unlike memory foam, which must only be wiped.
Replacing your CPAP cushion is one of the simplest ways to improve your therapy experience, and it's the part that wears fastest. This ResLab cushion combines premium medical-grade silicone with a design built for comfort, seal integrity and ease of use — and because your frame and headgear stay as they are, your fit doesn't need relearning. Whether you're replacing a worn cushion or keeping a spare on hand, it delivers the reliable seal your therapy depends on. Once you've confirmed your size, the 2, 3 and 5 packs bring the cost per cushion down considerably.
This is a ResLab replacement cushion and is not manufactured by or affiliated with ResMed. It is a component of a medical device used for the treatment of obstructive sleep apnoea under the direction of a qualified healthcare professional, and is designed for compatibility with the ResMed AirFit™ F20 and AirFit™ F20 For Her full face masks. The mask frame and headgear are not included and are sold separately.
Magnets and implanted medical devices. This cushion contains no magnets. However, the AirFit F20 headgear uses magnetic clips, so the assembled mask is not magnet-free. Magnets can interfere with implanted devices and metallic implants. Consult your doctor and your device manufacturer before using a mask with magnetic clips if you or anyone sharing your bed has:
If any of these apply, speak to your clinician about ResMed's non-magnetic (NM) headgear options before use, and keep magnetic components at least 150 mm from any implanted device.
Confirm the cushion matches your exact frame model and size before use — an incorrect fit reduces seal quality and therapy effectiveness. Do not share a cushion between users; cushions are single-user items. Inspect the cushion regularly for cracking, stiffening or discolouration and replace it if the seal is compromised. Never block or modify the mask vent, which sits in the elbow and is how exhaled air leaves the mask; a blocked vent allows carbon dioxide to build up inside the mask.
Please refer to the official AirFit F20 user guide supplied with your mask for complete information on contraindications, warnings, precautions and instructions for use, and consult your healthcare provider to confirm this product is appropriate for your therapy needs. If you notice persistent leaks, discomfort, skin irritation or any change in mask performance after fitting, discontinue use and consult your CPAP provider or healthcare professional.
