They also not recommended for under-the-nose masks such as the Respironics Amara View or DreamWear & the ResMed F30, or total face masks such as the Respironics FitLife.*Snugz Nasal Mask Liners will fit all nasal masks, but are not intended for nasal pillows (under the nose).*A note about mask leakage* A better seal is not necessarily a more airtight seal. Snugz provide a better seal by allowing micro-leakage through the fabric. This breathability keeps your mask feeling cooler & prevents a sweaty, slippery mask cushion that will inevitably slip & lead to loud noises that wake you up. With Snugz, those noisy disturbances will be history & your sleep quality should improve. Your CPAP machine may register some leakage & it may be possible to feel some leakage through the Snugz fabric. CPAP machines automatically adjust for this leakage & what matters most is your AHI and having fewer disturbances. While its always smart to check with your care provider, if you are sleeping better with fewer disturbances, & your AHI is low, your Snugz is doing its job.
