I use the bike shop filter masks most of the time because I notice a
difference when I don't - the traffic smells noticably worse and my
throat is more aggravated after my commute. That may be a purely
cosmetic difference, but it's enough to make me happy. It also means
I notice smokers less while I'm riding which is a pleasant benefit.

Of course, while I'm actually wearing the mask all I really notice is
that my breathing is obstructed.
