Worth the extra money if you hate the Silicone Mask
I was very surprised at the difference between the AirTouch (this mask) and the AirFit (the silicone version) for the F20. For me, the F10 Silicone mask has always worked pretty good, but required a significant amount of "strap-tension" to seal correctly. I decided to try the F20 (silicone model) in the same size (M) I was using in the F10 for a comparison, hoping for less "strap-tension" and morning facial impressions. The F20 (silicone) fit great and sealed better than the F10...But , the mask became less comfortable under higher pressure...seem like the edges of the mask became "sharp?" feeling, scratchy feeling. compared to the F10. SO...I decided to try the F20 AirTouch mask (same sizing as the silicone mask, M, for me) before switching back to the F10. I will not be switching back to the F10... This memory foam cushion is the most comfortable mask yet! It seals great with a lot less "strap-tension" compared to the Silicone Masks. Also, I do not get the "mask seal area-impressions" on my face anymore (keep in mind, you will still have strap impressions). Based on the results...it is worth the extra money for me and hope you find this helpful...good luck.
