Masks:For all Full Face masks: Masks that cover nose and mouth and reach to middle of lower lip, except:
Chin Full Face Masks:
Regular full face masks reach to the middle of lower lip but Chin Full Face masks reach below the chin, (reach below lower jaw / fit over the chin).
Gel Liner for Chin Full Face Masks are under "Chin Full Face Gel Liner"
Note:
Masks that do not have a forehead arm like Quattro FX and AirFit F10, as these masks have a common complaint that they often leak. Masks need to be connected at upper and lower boundaries and not at mid and lower boundaries, as a result they are notorious for leakage and the gel liner might still not seal completely, but it will still be fully protective from facial trauma.
Sizes:
Small and Large
Small Gel Liner covers Small and Medium Full Face Masks.
Large Gel Liner covers Large and X Large Full Face Masks.
