The ResMed AirFit F20 is a full-face CPAP mask designed for patients who breathe through their mouth during therapy, or who require a secure, stable seal across varying pressure levels. This guide covers everything a prospective buyer needs to know, from construction and compatibility to replacement schedules and available sizes.

What the AirFit F20 Is and How It Works

Design and Construction

The AirFit F20 features an InfinitySeal cushion that covers both the nose and mouth, creating a reliable seal with minimal contact pressure. The integrated frame is lightweight and designed for consistent performance across a full night of therapy. All components are latex-free, making the mask suitable for patients with latex sensitivities.

Fit System and Sizing

The mask is available in three cushion sizes: small, medium and large. An additional extra-small cushion is sold separately for patients with smaller facial profiles. The magnetic clip system on the headgear makes nightly fitting straightforward, allowing the mask to be removed and replaced without readjusting the straps each time.

Airflow and Comfort Features

The AirFit F20 incorporates a diffused vent design that disperses exhaled air quietly, reducing disturbance for bed partners. The cushion adapts to facial contours under pressure, which contributes to a consistent seal during movement. The elbow connector rotates 360 degrees, allowing tubing to be routed in whichever direction suits the sleeper's position.

Compatibility and System Integration

Compatible CPAP, APAP and BiPAP Devices

The AirFit F20 is compatible with the majority of ResMed AirSense 10 and AirSense 11 devices, including CPAP, APAP and bilevel (BiPAP) configurations. It is also suitable for use with third-party machines that accept a standard 22 mm tubing connection. Clinicians frequently recommend the AirFit F20 for patients transitioning from nasal masks who require a more secure airway seal.

Humidifier Compatibility

The mask is compatible with heated humidifier systems, including the ResMed HumidAir integrated humidifier. When used with a heated tube such as the ResMed ClimateLineAir, condensation in the tubing is significantly reduced, supporting comfortable nightly therapy. The humidifier and tubing are sold separately and are not included with the mask.

What Is Not Compatible

The AirFit F20 headgear and cushion components are not directly interchangeable with those designed for the AirFit F30 or AirFit N20 ranges. Buyers should confirm the correct part reference before ordering replacement components. Using incompatible accessories may compromise the seal and affect therapy performance.

What Is Included and What Is Sold Separately

Standard Package Contents

A standard AirFit F20 starter kit typically includes the following components, all brand new:

• Full-face cushion: one InfinitySeal cushion in the selected size, designed for direct contact with the face.
• Mask frame: the integrated plastic frame that holds the cushion and connects to the headgear.
• Headgear: the fabric strap system with magnetic clips, suitable for most adult head sizes.
• Elbow connector: a rotating connector that joins the mask frame to the tubing.

Items Sold Separately

The following items are not included with the standard mask kit and must be purchased separately:

• CPAP tubing: standard or heated tubing is not included and must be sourced to match the patient's device.
• Humidifier: a compatible humidifier such as the ResMed HumidAir is sold separately.
• Replacement cushions: spare or alternative-size cushions are available individually as replacement parts.
• Chin strap: not required for most users, but sold separately for those who need additional jaw support.

Replacement Schedule and Ongoing Maintenance

Recommended Replacement Intervals

Regular replacement of consumable components maintains hygiene and ensures a consistent seal. The schedule below reflects general guidance; individual clinicians may recommend different intervals based on therapy requirements.

• Cushion: replace every one to three months, or sooner if the seal becomes inconsistent or the silicone shows visible wear.
• Headgear: replace every six months, or when elasticity is reduced and the fit can no longer be adjusted adequately.
• Frame: replace every twelve months, or when cracks, discolouration or structural changes are observed.
• Elbow connector: replace every twelve months alongside the frame, or if airflow feels restricted.

Daily Cleaning Guidance

The cushion and frame should be cleaned daily using mild soap and warm water, then rinsed thoroughly and air-dried away from direct sunlight. The headgear should be hand-washed weekly. Disposable wipes designed for CPAP accessories can be used for convenience between washes, though they are not a substitute for a thorough daily clean. Replacement components are available as individual items from CPAP Supply UK.

Key Features at a Glance

• InfinitySeal cushion: a silicone cushion designed to conform to facial contours for a reliable, comfortable seal under varying pressure levels.
• Magnetic headgear clips: integrated magnets allow the headgear to be removed and reattached quickly without re-threading straps each night.
• Quiet vent design: a diffused exhalation port disperses exhaled air to minimise noise and airflow directed at a bed partner.
• Latex-free materials: all components are free from latex, making the mask suitable for patients with latex sensitivities.
• 360-degree rotating elbow: the elbow connector rotates fully, allowing tubing to be positioned for any sleeping posture.
• Three cushion sizes: small, medium and large are available as standard, with an extra-small cushion sold separately.

Summary: Choosing the AirFit F20

The ResMed AirFit F20 is a well-established full-face mask designed for reliable nightly CPAP, APAP and bilevel therapy. Its InfinitySeal cushion, magnetic headgear clips and quiet vent design make it a practical choice for mouth-breathers and patients who require a secure airway seal. Sizing options accommodate a wide range of facial profiles, and the modular design means individual components can be replaced as needed without purchasing a complete new kit. Patients are advised to consult their clinician to confirm that a full-face mask is appropriate for their prescribed therapy before purchasing. Replacement cushions, headgear and frames are all available separately from CPAP Supply UK.
