ResMed AirTouch F20 Replacement Cushion

ResMed replacement items work the best

I've tried several foam face masks and they all leak for wear out quickly. The ResMed mask is the only one the really works well. It is a lot more expensive, but well worth the extra price.

Bought it by confussion

I tought mask was N20. Try to return it. Haven't find how.

Good mask seal
