Bruise on bridge of nose. Why?

My hybrid mask broke so I've been using my Airfit 20 full mask. Problem is I keep getting a bruise on my nose that hurts. I wear glasses during work hours and it's sore. Why does this happen? My mask is not too tight.

I had the F20 mask and gave up on it after about 4 days. It was starting to irritate the bridge of my nose too, and I couldn't solve the air leaks blowing into my eyes issue. I understand from others that they have solved these issues by using a mask liner of cotton t-shirt material. You can buy them, or make your own apparently. You might want to try a piece of cotton material at the bridge of your nose only to see if that helps. Here is a link to one of the commercial manufacturers of them. I think to buy them, they can be kind of expensive, so that is why people make their own... Probably old t-shirt material is softer too.

Remzzzs Mask Liners

The bruise will almost certainly be due to you mask being too tight at the top. It is quite possible, especially with the F20, that you need it that tight to stop it leaking into your eyes. If this is so, a new mask maybe in order. Perhaps an Amara View or a DreamWear full face?

I suggest looking at something like "snugz mask liners" or "Pad A Cheek" which will reduce the friction of any mask you may use.
