This replacement AirPillow Seal (Nasal Pillow) is designed for use with all F&P Brevida CPAP and BiPAP Masks. Brevida's innovative AirPillow inflates to form a gentle, effective seal on the nostrils; and features side supports on the outside of the nose for added comfort and stability. Fisher & Paykel Brevida Pillow Cushion Replacement SIZING: Two Fisher & Paykel Brevida AirPillow Nasal Pillow sizes are available -- ExtraSmall-Small and Medium-Large -- to fit a wide range of users.

If you would like to change the size of your mask, you can just purchase a different nasal pillow size and fit it to your existing mask frame To determine the size of your seal, check the VisiBlue area on the front of the frame for the embossed letters XS-S or M-L.
