The invention discloses a gas turbine air inlet system filtering efficiency online test system, comprising a wind speed measuring instrument used for measuring an air flow field in a gas turbine air inlet system, an upstream isodynamic sampling device and a downstream isodynamic sampling device respectively obtaining upstream samples and downstream samples, a cleaning and blowing device used for carrying out back-blowing cleaning, a reference filter unit used as a reference comparison test for filtering the sample of the upstream isodynamic sampling device to obtain a reference comparison sample, and a counting efficiency testing device used for carrying out particle counting on the upstream sampling, the downstream sampling and the reference comparison sampling respectively and calculating the filtering efficiency of the filter unit to be tested. The air inlet system filtering efficiency of the gas turbine in the actual operation environment can be effectively tested, the real-time health state of the gas tu
