I'm wondering how many people wash their new hose and mask before using them for the first time or do they just use them out of the box?

It seems no matter how tight I sinch this nasal mask if I lay on my side just right the air leaks out. I've tried two different masks and the same thing happens. The one I'm using now I believe is called the Respironics profile lite gel mask. I've tightened it so much that today I have a big bump in...

I'll let it go for $50. pm me for further info.

Brand new in unopened manufacturer box.

$100 + $12 shipping.

This is my post in case anyone wants to pm me.
