The present invention relates to a nanofiber filter formed on both sides of a base with improved heat resistance and, more specifically, a manufacturing of a heat resistant nanofiber filter formed on both sides of the base with use of electrospinning to resolve a lower heat stability of an existing nanofiber filter. In the present invention, a nanofiber filter formed on both sides of a base is manufactured by steps of stacking a first heat-resistant nanofiber on one side of the base and continuing to electrically spin a second heat-resistant polymer nanofiber toward the other side of the base without the first heat resistant nanofiber. In the present invention, the manufactured filter has an efficiency and heat resistance and is cost-effective by installing a nanofiber whose diameter is larger in a direction of receiving air and by installing a nanofiber whose diameter is smaller in a direction of discharging air when air filter process is made. |
