The present invention relates to a see-through sanitary mask, in particular, a first mesh (1), a nanofiber filter (2) formed by electrospinning on one surface of the first mesh (1), and the nanofiber filter ( 2) is disposed opposite to the first mesh (1) so that the second mesh (3) is integrally coupled to the first mesh (1) and the nanofiber filter (2); 10), wherein the mask body 10 has water repellency and a water repellent agent is treated on the mask body 10 to increase the strength of the nanofibers of the nanofiber filter 2, and the nanofiber filter ( 2) is nylon, polyacrylonitrile, polyvinyl fluoride, polyvinyl alcohol, polyethersulfone, polyimide, and at least one synthetic resin selected from the group consisting of polyaramid by electrospinning to nano made of fibers. Such a see-through sanitary mask has a collection efficiency of 85.0% or more by the ASHRAE 52.1 (weight method) test method, a breathability of 500 cfm or more by the ASTM D737-96 method, and a light blocking rate of 60.0% or more by the KS K 0819 method. |
