The Silicone seal is compatible with both the Quattro Air Full Face Mask and the F10 Full face Mask range
The dual-wall Spring Air™ cushion provides a secure seal. It’s light, flexible and designed to gently inflate against your face, to maintain a seal, even as you move during the night. When you’re asleep, the circular diffused venting directs air away from you and your partner so both of you can enjoy a peaceful night’s sleep.
