Abstract: In order to seek the measures and techniques to reduce indoor air pollutants,a series of couaterful tests were carried out, using four plants such as Sansevieria trifasciata, Chlorophytum capense,Clivia miniata, Ficus elastica as testing materials. The results show that all theses plants can absorb interior poisonous and harmful air. The difference of absorption effect is clear. The effect of Sansevieria trifasciata is the best, compared with antitheses ,which can absorb 64.6% the total of formal dehyde,61.4% of dimethylbenzene，64.8% of TVOC within seven days. The effect of Ficus elastica is the worst.
