What is Nanofiber?

A definition of nanofiber is a substance that has a diameter of 1nm to 100nm and a length of 100 times the diameter.

Nanofiber filters out most of fine particles and microbes due to very small space between individual fibers. A large surface area provides improved absorption. A very small diameter of individual fibers significantly improved airflow by eliminating the vortex generated from fibers in the back.
