The ResMed AirTouch F20 Cushion is a memory foam CPAP mask cushion designed for use with the AirFit F20 full-face mask frame. It is a consumable component that requires regular replacement to maintain a reliable seal throughout the night. Several common errors in fitting, cleaning and replacement timing reduce its effectiveness and shorten its usable life.
The AirTouch F20 cushion is made from UltraSoft memory foam rather than silicone. This material conforms to facial contours at therapy pressure, which can improve comfort at the interface. The foam structure is fundamentally different from silicone cushions and must be handled accordingly.
Because the material is foam, it absorbs moisture and oils from the skin. This directly affects how long the cushion remains hygienic and functional. Understanding this distinction prevents the most common care errors.
The AirTouch F20 cushion fits only the AirFit F20 frame. It is not compatible with the AirFit F30, AirTouch N20 or other ResMed full-face frames. Confirm the frame model before ordering. The cushion and frame are sold separately in many configurations, so check what is included with any purchase.
Using the wrong cushion size is one of the most frequent causes of mask leak. ResMed provides a sizing gauge to guide selection. Measure as directed in the manufacturer instructions. A cushion that appears to fit but is the wrong size will not seal reliably, particularly as therapy pressure increases throughout the night.

Pulling the headgear too tight to compensate for poor seal is a common error. With a memory foam cushion, over-tightening compresses the foam unevenly, accelerates material fatigue and can cause facial discomfort. A properly fitted AirTouch F20 cushion should seal at a moderate headgear tension. If a firm seal requires excessive tightening, the cushion size or condition is likely the cause, not the headgear adjustment.
The cushion clips to the AirFit F20 frame via a magnetic connection. Incomplete seating of the cushion at any point around the frame perimeter will create a leak path. Run a finger around the full perimeter of the cushion after attaching it to confirm even contact. Do not force the connection. If the cushion does not seat smoothly, check for debris or damage on the frame clips.
Oils from moisturisers, sunscreen and similar products degrade memory foam faster and compromise the seal at the interface. Fit the mask to a clean, dry face. Avoid applying skin products to the contact area before sleep onset. This is particularly important with foam cushions, as they are more susceptible to oil absorption than silicone alternatives.
The AirTouch F20 cushion must not be submerged in water or cleaned with alcohol-based wipes, CPAP cleaning machines using ozone or UV, or any abrasive material. Memory foam breaks down rapidly when exposed to these methods. The manufacturer specifies wiping the cushion with a soft damp cloth using mild soap, then allowing it to air dry away from direct sunlight. Follow the manufacturer instructions. This guidance does not replace them.
Fitting a damp cushion traps moisture against the skin throughout the night and accelerates foam deterioration. After cleaning, allow the cushion to dry fully before reassembly. Do not use a hairdryer or place the cushion in direct sunlight to speed drying, as heat degrades the foam material.
Silicone cushions tolerate more aggressive cleaning than memory foam. Users who have previously used silicone interface components sometimes apply the same cleaning routine to the AirTouch F20 cushion in error. The two materials require different protocols. Check the cleaning instructions specific to the AirTouch F20 cushion rather than applying a general CPAP cleaning routine.
ResMed recommends replacing the AirTouch F20 cushion approximately every four weeks with nightly use. Memory foam loses its ability to conform and seal as it ages, compresses and absorbs contaminants. A cushion used beyond this interval may appear intact but will not perform to specification. Mask leak data in your CPAP device or app can indicate when seal quality has declined, but visual inspection alone is not a reliable guide.
The AirTouch F20 cushion is a consumable. It is not designed for indefinite reuse. Factor replacement cost into the ongoing cost of therapy. Budget for a new cushion approximately monthly. Purchasing in advance avoids gaps in supply that may compromise nightly compliance.
ResMed produces several cushion types across the AirFit and AirTouch range. Part numbers are distinct for each size and model. Ordering the wrong cushion because of an assumed compatibility is a straightforward error to avoid: check the part number against the frame in use before ordering, and ask before ordering if there is any uncertainty.
The ResMed AirTouch F20 Cushion performs reliably when fitted, cleaned and replaced correctly. Most problems trace back to three areas: incorrect size selection, cleaning methods suited to silicone rather than foam, and delayed replacement beyond the four-week interval. Confirm compatibility with the AirFit F20 frame, follow the manufacturer cleaning instructions precisely and treat the cushion as the consumable it is. When in doubt about sizing or compatibility, ask before ordering.
