Nanofiber is a substance that has a diameter of 1nm to 100nm and a length of 100 times the diameter. *nm = 1/1,000,000,000m 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. Nanofiber is known to be used in medical purposes for removing poisonous and hazardous chemical substances such as highly protective face mask but it is also widely used in IT fields such as rechargeable batteries and supercapacitors. Nanofiber is used in the iron and steel industry, combustion furnace, and related industrial exhaust filters. Also used in in medical materials, cosmetic materials, high-performance filter, highly protective facemask, clothing material, soundproofing, heat-insulating material also it is used for air filters in heavy trucks. Recommended replacement interval is 1 year or 10,000 km. HKS recommends more frequent replacement in areas with high traffic and air pollution. |
