“Upgrade from a Zest. As with any mask change, takes a bit to get used to.
Fit Pack allowed to find the most comfortable fit for my nose.
Very comfortable, minimal leaks. Quiet.
Diffuser doesn't blow all over partner.”
“this fit pack was great .I decided to try the medium mask as i use a large one normally and it worked okay. I now have a spare if anything happens to my normal mask.
I would suggest your customers try one”
