After trying around 25 different N95 masks, this is the one I like best. It is comfortable, seals well on different face shapes and sizes, and is very easy to breathe through, partly because of the large surface area when unfolded. I also like that it folds flat, so it is easy to carry in a shirt pocket or purse. It is not exactly stylish, but appearance is not the reason I wear a mask One important detail is that it comes in regular and small sizes, so choosing the right one matters. The regular size fits all of the adults in my family except my petite daughter, who needs the small size.
