A search of specific surface areas of some cotton fibers is in the low double digits m2 for a gram of cotton fiber. Activated charcoal is 3000 m2 per gram. Seems like a nonissue.

Just a curiosity question. We have a research group raising concerns that face coverings could inhibit one's ability to smell, a sense they believe they really need to have in a laboratory setting. I've seen publications disputing concerns around carbon dioxide entrapment and heard plenty of practical comments about being able to smell cologne through the coverings, but I haven't seen anything published on this topic. It sounds like a weak argument to me, but I don't want to simply discount this concern without a good faith effort to find out if there's any real evidence that this is a valid concern. Any thoughts/comments that you would care to share?
