Additional Information
Sleeping with mouth open
The AirFit F20 is the ideal choice if you tend to breathe through your mouth while sleeping. Its full face design covers both the nose and mouth simultaneously, keeping therapy pressure effective without leaks even when the mouth is open.
Allergies or nasal congestion
If you frequently experience nasal congestion due to allergies or a cold, a full face mask ensures your CPAP therapy continues uninterrupted, as you can still breathe through your mouth.
Sleep apnea patients requiring high pressure
Full face masks are generally more stable at higher pressure settings (above 12–15 cmH₂O). The AirFit F20 with InfinitySeal technology maintains a consistent seal even at high pressures.
Sleep position — back sleeping
The AirFit F20 is designed for back sleepers. If you sleep on your side, consider a nasal or nasal pillow mask, which is lighter and less prone to shifting.
FAQ
How do I determine the right mask size?
ResMed provides a sizing guide that can be downloaded — place the guide on your face following the instructions to determine whether you need a Small, Medium, or Large. In general, Medium fits most users. Contact us if you are unsure about the right size.
How often should mask components be replaced?
ResMed's recommended replacement schedule:
- Cushion: wash daily, replace every 6 months
- Frame: wash every 2 days, replace every 3 months
- Headgear: wash weekly, replace every 8 months
Regular replacement ensures an optimal seal and maintains hygiene.
How do I properly clean the AirFit F20?
Disassemble all components (cushion, frame, headgear, elbow). Wash with warm water and mild soap, rinse thoroughly, then air-dry in a shaded area away from direct sunlight. Do not use alcohol or bleach-based products, as they can damage the silicone.
Is the AirFit F20 compatible with the AirMini?
Yes, a dedicated AirFit F20 for AirMini adapter is available, allowing this mask to be used with the AirMini device. The adapter is sold separately — contact us for more information.
