I've been arguing with my CPAP supply person who swears I should wear a medium. But the medium felt too small. To prove them wrong, i paid many times more than what I would pay at my supply house (for a full mask, tubing, and filters) for this mask insert only. But it was worth the purchase, because I proved them wrong - I have been wearing this mask insert at night (using the frame from my Medium mask) with my machine, and it works MUCH better than the medium I had before. I only wish Resmed would make "in between" sizes, as this one pushes the limits - very comfortable, but so large I get some air leaks. A medium - large would be perfect for me.... but they don't make one. So Large will have to do.

I have been using the Resmed AirTouch F20 mask for about 4 years and because the foam liner doesn't hold up well I thought I would try this model. Unfortunately the silicone liner is uncomfortable and doesn't fit well enough to prevent air leaks so I can't use these.

Mask works as should. The only drawback is that the sillicon seal tapers to a thin edge. This improves the chshion fit; but if the mask shifts slightly the cpap pressure begins to push under the shifted edge. This loss of pressure causes the cpap to compensate for the loss. As the quanity of air is increases, that will wake you from your sleep.

Fit my face much better than the medium which I had to strap down super tight to get a proper seal. Much more comfortable now.
