airfit N30i vs F30i

Hi,
I currently use the f20 facemask. I really don't like it. I tried the airfit N30i but I can't do the nose thing. I am wondering if the airfit F30i would work better because I do sleep with my mouth open. My question is will the frame for the N30i work for the F30i? So all I would have to order is the mask and the head gear? Or do I need to order the entire F30i kit?
I use the ResMed Airsense 10

Thank You!
Jane

Near as I can find...not compatible...when looking at just the frames the F30i has the little magnetic clip thingies for the headgear for the F30i.
I don't see the clips on the N30i frame.

And I found one website with the products for sale that specifically said the N30i frame was NOT compatible with the F30i.

Please note - not compatible with AirFit F30i

THANK YOU!
