Whats the difference

[spirit390]

I use an umff with the standard medium cushion and found(on another sight) these medium shallow cushion on sale. What makes them shallow? Thanks in advance

The skirt walls are not as wide from front to back; i.e. the mask frame sits closer to your face. It reduces the contained volume of the mask. Other than more efficient purging during exhale, I don't know what the advantage is. But some people must prefer them or they wouldn't sell.

They were quite a bit cheaper and since I do not have insurance and have to pay for all my supplies out of pocket I will give it a shot. Thanks

Ah! Apparently they DON'T sell very well!

Never tried one, but I'm guessing people with large noses may not be able to use a shallow cushion.

Link - not true at all (you haven't seen my nose have you), though where the 'bigness' is might matter. I use a small shallow and the difference is as much in the bridge width and depth (according to a Cpap.com phone conversation) as anything.
