If you’re looking for something similar to cover your face in crowded public places, then a simple cotton mask is a popular option. This adjustable cotton face mask has straps that loop around your ears to keep it in place. Simple cotton masks lack the N95 and N99 anti-pollution capabilities of other masks, but they do provide coverage for your mouth and nose in public spaces. Because it is made from cotton, this mask is also washable. It’s recommended that you wash it one or two times a week, depending on how much you’re wearing it.
