Hi lucky - that is a good question! Although I can suggest almost any type/kind of mask, I usually find this is a decision that needs to be made on a personal level. Some folks I know prefer the N-95 mask because of the extra room around the external nares (nostrils), of the nose. Still others prefer the standard surgical mask for themselves. And then, there is everything in between.
What do you find works well for yourself?
