Beschreibung
Zusammenfassung:	The present invention relates to a filter for an air cleaner comprising a nonwoven fabric substrate capable of indicating service life. The filter can be manufactured by a method comprising the steps of: coating and drying a surface using an indicating aqueous solution containing anthocyanin; adjusting the pH of the surface; and surface treating the surface to include porphyrin and metal phthalocyanine complexes on the surface. The filter of the present invention comprises a nonwoven fabric substrate capable of indicating the service life and accurately determining the service life and replacement timing of the filter for the air cleaner without deteriorating the performance of the filter for the air cleaner. 본 발명은 안토시아닌을 포함하는 지시 수용액을 사용하여 표면을 코팅 및 건조하는 단계; 표면의 pH를 조절하는 단계; 및 표면에 포르피린: 및 금속 프탈로시아닌 착체를 포함하도록 표면처리하는 단계;를 포함하는 제조방법에 의하여 제조되는 수명 안내가 가능한 부직포 기재를 포함하여, 공기청정기용 필터의 성능을 저하시키지 않으면서도 공기청정기용 필터의 수명 및 교체 시기를 정확하게 판정할 수 있는 수명 안내가 가능한 부직포 기재를 포함하는 공기청정기용 필터에 관한 것이다.
