Not so fast.
The f&p simplus and the Resmed Quattro air share the same geometry. An air inflated cushion with 2 bottom anchors and a single piece top anchor on the forehead. I don't think you would find any appreciable difference between these two.
The F10 on the other hand has dual top anchors and they are on the cheekbones. So it's a different geometry and I believe it's more forgiving to people who are side sleepers due to its dual anchors. And in my opinion, I could wear it much looser than the Quattro air. Also, 4 anchors give it a bit more stability. One night while I was using the F10, one of its bottom anchors was dislodged but it still didn't go into large leak territory.
I recommend that you try the F10 if you really want to try another FFM.
Another thing: if you are running an open range of 4-20, you may want to tighten the range a bit. And if your 95% pressure is less than 15cm then, you may ultimately want to gravitate towards the nasal pillows mask - the Resmed P10. Now that is a cult. And......Resistance is futile!
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.
