Snugz Mask Fit Information

Snugz is a “one-size-fits-most” liner for CPAP masks. We currently offer two Snugz products:

Snugz Full-Face Mask Liners will fit all sizes of all nose-and-mouth masks except for the ResMed Mirage Quattro, the extra-large Fisher and Paykel Forma, and the large Respironics ComfortGel. They are also not recommended for under-the-nose masks such as the Respironics Amara View or DreamWear and the ResMed F30, or total face masks such as the Respironics FitLife.

Snugz Nasal Mask Liners will fit all sizes of all nasal masks (around the nose only) except for the ResMed Mirage Activa. These nasal CPAP mask covers are also not intended for nasal pillows or nasal prongs (under the nose).

Warnings / Cautions: If at any time you are concerned that Snugz is interfering with therapy or causing increased irritation/discomfort, stop using Snugz and ask your sleep professional.

I used CPAP for many years and have continually battled with leaky masks. These are the greatest! What a difference. Comfort at last!
