• . The electrostatic fiber filter used in the existing fine dust mask has a problem that static electricity formed on the surface of the fiber is lost over time.
• In addition, when moisture or water comes in contact, the static electricity function disappears, and the filter efficiency drops sharply and cannot be reused.
• In particular, even if it is soaked in ethanol for more than 3 hours, the nanofibers do not melt or warp, so it can be used for more than a month if ethanol is sterilized and washed.
• It was also confirmed that even if the filter was bent 4000 times, the performance of the KF80 mask (600 nm particles, 80% filtration efficiency) was maintained.
