The invention relates to the field of air purification, and aims to provide an environment-friendly method for evaluating the effect of a formaldehyde purifying agent. According to the method, the formaldehyde removal effect of the air purification product is tested by adopting the environment-friendly E0-grade medium-density fiberboard, compared with an existing detection method, the method has the advantages of being convenient to operate, short in test period, wide in test range, low in cost and the like, a precise and expensive instrument is not needed, a formaldehyde solution does not need to be manually injected, harm to the body health of a tester is small, and the method is suitable for popularization and application. The environment is not polluted; the method not only can test the formaldehyde removal rate of the air purification product, but also can test the attenuation rate of the product, so that the durability of the purification effect is judged, the actual application effect of the air purifi
