You didn’t specify the student’s level. So, I think it depends on the type of contaminants the student will encounter.
If you allow your students to take their lab coats home on a daily basis, then I don’t see a problem with re-usable masks because any contaminants would presumably be “harmless”. On the other hand, upper classmen or grad students who are not allowed to take their lab coats home should be wearing disposable masks.

Are reusable masks okay in lab or only disposable ones because of chemical contaminants?
