My go to facemask solution is wearing two masks. I wear a KN95 which people can buy on line. Then if I want to be extra careful I add a homemade woven cotton mask over the top. This keeps me from touching the kn95 mask. Also the kn95 mask has structure so the cotton mask can't block my nose and mouth. I also think my cotton mask keeps my kn95 mask cleaner since it's basically made of paper. I can wash my cotton mask in the kitchen sink. But I don't think it's comfortable to wear just the cotton mask. I breathe it in and it sticks on my nose and mouth so I can't breathe.
