The present invention aims to resolve low thermal stability, which is a flaw of an existing nanofiber filter. To this end, a double-sided nanofiber filter having enhanced thermal resistance is manufactured by electrospinning thermal resistant fiber on both sides of a base material. The double-sided nanofiber filter is manufactured by the steps of: stacking inorganic nanofibers on the base material; manufacturing double-sided nanofiber by continuously electrospinning thermal resistant polymer nanofibers on a side of the base material, on which the inorganic nanofibers are not stacked; and arranging thick nanofibers in the direction of air introduction and thin nanofibers in the direction of air discharge during an air filter process. Therefore, a functional filter, which has filter efficiency, price competitiveness, high efficiency, and thermal resistance is manufactured. |
