Not just those, it also includes surgical grade masks that are cone shaped but not N95. Wife had boxes of those from her cancer operations and that's what we've been using but only a few left, then we go to the flat surgical masks you see everywhere. We've bought cloth masks but, for several reasons, are using surgical masks until we can no longer get them.
