Sure, but for the short periods of time I could potentially have my mask off for, I'm not sure how much of a difference it would make— I am generally not wearing my mask for longer than an hour or two.

Just a note, the article you linked doesn't seem to mention how long is too long to wear a mask if you want to prevent mask mouth, etc.. Maybe I missed it.
