The utility model belongs to the field of detection equipment, and discloses a device for testing the particle filtering effect of a plant. The device comprises a sample chamber for placing a plant to be tested, wherein the sample chamber adopts a transparent structure and is communicated with the outside through an air inlet pipe and an air outlet pipe respectively; a detector is arranged on the air outlet pipe; a second detector and a particle generator are arranged on the air inlet pipe, and the second detector is positioned between the particle generator and the sample chamber. A plant to be tested is placed in the closed sample chamber, then a fan circulates air, and the particle absorption effect of the plant can be achieved through measuring the content of particles of the air entering the sample chamber and going out of the sample chamber; the particle generator can provide a continuous and stable particle contamination source for the sample chamber to ensure the accuracy of the measurement results.
