The process of manufacturing a quality face mask has several factors. First, the materials used in the manufacture should be as efficient as possible. For example, an N95 mask should filter out 95 percent of very small particles. A good quality mask should be made from nonwoven material with multiple layers. A Florida Atlantic University professor studied the efficiency of different types of materials and found that many of them could offer an adequate level of protection. Then, it should be comfortable for the wearer to wear.
