Resmed full face mask f 20

I recently started useing a new facemask from Resmed, the F-20. It is very comfortable for a full face mask. However blisters formed on the bridge of my nose. This was not caused by unusual pressure since the fit is excellent and mask basicly sits on your face without leaks. The material that touches your face is memory foam. I have continued to clean the mask each night and I did not feel any irritation but the skin blistered. Has anyone had this experience?

I had the one you have with the memory foam Tried it for 3-4 days then returned it for the other F20 model I like the one without the memory foam much better. Good luck

I am not sure what is causing the blustering it could be either chemical or from rubbing of the mask against the skin
