Mask sizes
My first post .... I hope somebody can help. I have just purchased a Resmed AirFit F20 full mask in large size. I have now found that I am more comfortable in the F20 medium size cup. There appears to be no problem attaching the medium size cup to the large size harness and cup mount. It clicks in OK and appears to fit. Does anybody know if mixing a medium size cup with a large size harness and cup mount affects the functionality of the mask? Are F20 cup sizes interchangeable? Many thanks.

Welcome to Apnea Board, HairPower.
I was issued originally a medium F20 AirFit, when I discovered I needed a small. Been on Small ever since. Yes I believe they're fully interchangeable.

As Walla Walla and Dave have said, it doesn't matter. The headgear is designed to hold Sm, Med, and Lg size cushions for both the AirFit F20 and the AirTouch F20 making it a pretty good design in my opinion.

You can swap the s,m,l sizes. The headgear doesn't matter as long as it will tighten.

Thanks for the heads up gentlemen. Makes it a pretty versatile mask.
