Overnight mask leaks can lead to dry eyes or fragmented sleep. The Anti–Leak Strap AirFit F20/F30 adds gentle support to help steady your seal so therapy feels consistent from lights out to wake up.

Designed for AirFit masks only, it secures at the mask elbow for a more secure fit without covering the exhalation ports—so you can breathe normally and vent as intended. If you’re pairing with a new mask, consider the AirFit F20 Full Face Mask for a compatible setup.

• Helps reduce leaks: Added support at the elbow steadies the seal.
• Normal venting: Strap won’t block exhalation ports or CO₂ venting.
• Soft and lightweight: Comfort without added warmth or bulk.
• Made for fit: Works with AirFit F20 and AirFit F30 only.
• Quick to attach: Simple to add, easy to fine‑tune.
• Color options: Choose gray or baby blue.
