The utility model relates to a filter testboard which comprises a fan, an air chamber, an air duct, an air inlet box and a dust generating device which are sequentially arranged, the air duct is composed of an upstream pipeline, a test pipeline, a downstream pipeline and a tail end pipeline which are sequentially connected from the air inlet box to the air chamber, and a first filter is arranged in the tail end pipeline. A downstream static pressure ring is arranged outside the downstream pipeline, a downstream sampling pipe is arranged in the downstream pipeline, a tested filter is installed at the tail end of the testing pipeline, a second filter is installed at the end, close to the dust generating device, of the air inlet box, a dust generating pipeline extending into the air inlet box is arranged on the dust generating device, an upstream static pressure ring is arranged outside the upstream pipeline, and a downstream sampling pipe is arranged in the upstream pipeline. And an upstream sampling pipe is ar
