Is that a problem? Yes... like I said and shown in my experiment that you can repeat yourself, most masks are like toys, not air sealed or fitted properly and a lot of air gets through the sides, doesn't matter if you breathe in or out, gaps are still there (you will notice cold air entering on the side of the mask when you breathe in, especially if you worn the mask for a while and it gets a little soggy). Of course, don't get me wrong.. they do work to a degree if fitted properly with the right grade of filtet, but the problem that people are putting too much faith in these things, especially the ones you buy from the combinis..
