Switching quattro mask cushion

Guys, does anyone know if the Quattro full face mask frame can fit different cushion sizes. I was set up with the Quattro medium at first, and found that I had problems with mask leaks. At that time my machine was set wide open from 4 to 20. t has since settled in at 18. I used a Ultra Mirage nasal mask, but even with chinstraps and taping mouth leaks are a problem. I'm considering giving the Quattro another try now that I am a little more experienced with CPAP. I read that some people had good luck with a smaller Quattro cushion, and wondered if I could just buy a small, to fit in my current mask frame to try.

As far as I know the quattro frame is specific to the cushion size. I have never been able to interchange them.

I have both the medium and large Quattro. The mask itself is quite different in sizing.

They are pretty adaptable and resistant to leaking on tougher machines - ResMed ASV and similar. You can pull it down pretty tight. But it will need new cushions often, and new headgear (straps) occassionaly to resist leaks at higher pressure.

Great mask, good choice for best quality therapy until you can adapt to a nasal or pillow mask. I use all 3, but go back to the FF mask when I am struggling for any reason. Hot in summer and humid weather though.

Good luck!
