The invention relates to a nondestructive testing method and testing system for a filter component, and the nondestructive testing method comprises the following steps: injecting a tracer agent at an inlet of the filter component, measuring the concentration of the tracer agent at the inlet in real time, and obtaining the concentration distribution data of the tracer agent at the inlet; measuring the concentration of the tracer agent at the outlet of the filter assembly in real time to obtain the concentration distribution data of the tracer agent at the outlet; calculating to obtain the average residence time, residence time distribution, delay coefficient and flow channel volume of the tracer agent in the filter assembly; and judging the defects, the service life and the pollution blockage degree of the filtering assembly. The fluid performance of different filter assemblies can be qualitatively and quantitatively detected and evaluated, whether the filter assemblies have defects or not can be judged, the s
