InfinitySeal™ Cushion – Engineered to Seal Where Others Fail

At the core of the AirFit F20 is ResMed’s InfinitySeal™ silicone cushion, designed using extensive facial-scan data.

Key advantages:

• Adapts to a wide range of face shapes

• Maintains a stable seal even at high pressures (up to 30 cmH₂O)

• Performs reliably during movement and position changes

• Reduces leaks without excessive headgear tension

This is one of the main reasons the F20 is trusted by clinicians worldwide.

👀 Open Field of Vision – Comfort Without Compromise

Unlike bulky full face masks, the AirFit F20 features a low-profile frame that:

• keeps your field of vision clear

• allows you to read or watch TV before sleep

• reduces feelings of claustrophobia

Comfort doesn’t mean restriction — and the F20 proves it.

QuietAir™ Elbow – Quieter Nights for You and Your Partner

The integrated QuietAir™ diffuser elbow gently disperses exhaled air, significantly reducing noise and airflow disturbance.

This results in:

• quieter operation

• less air blowing toward your partner

• improved sleep quality for both users
