Hi @gizmo1500 -- Welcome to Connect. I'm not allergic to the silicone but I have had issues with several masks and one of the masks I was looking to get was the Sleepweaver Anew (full face mask) which is not made of silicone. I finally found a cloth cover for my mask and that has helped tremendously - no more red CPAP nose and cheeks which I think was coming from the flapping and leaks from being too tight on my face.

Sleepweaver also has a nasal version of the mask which may work for you. It would be interesting to hear what your doctor says about the allergy. Do you use a humidifier with a heated hose? Here's a link to the non silicone masks: https://circadiance.com/sleepweaver/
