Who Is This Mask Best For?
The AirFit F20 is engineered to handle high pressures and mouth breathing while maintaining a secure seal.
Mouth Breathers
Full face coverage ensures therapy pressure is maintained even if your jaw drops during sleep.
Active Sleepers
The InfinitySeal™ cushion adapts to movement, maintaining seal integrity even when turning from side to side.
High-Pressure Users
The robust seal and frame stability can handle higher pressure settings without leaking or shifting.
Users with Claustrophobia Concerns
The open under-eye design removes the forehead bar, reducing the bulk feeling common in older full face masks.
Bedtime Readers
Without a forehead support, your line of sight is clear to read a book or watch TV before falling asleep.
Ideal for Varied Facial Shapes
ResMed studies show the F20 fits 99% of patients, making it the "go-to" choice for users who have struggled to find a mask that seals correctly on their unique facial contours.
Cleaning & Maintenance
Regular maintenance prevents bacterial buildup and ensures the silicone cushion maintains its sealing properties.
Daily Cleaning
Disassemble the mask cushion from the frame and wash to remove facial oils.
- Soak cushion in warm water with mild liquid detergent
- Gently agitate
- Rinse thoroughly with water
- Allow to air dry away from direct sunlight
Weekly Deep Clean
Wash the headgear, frame, and elbow to ensure hygiene.
- Hand wash components in warm soapy water
