Purpose / Context - Indoor air pollution in China has become increasingly serious, which has aroused wide concern among the public. The purpose of this paper is to study the effect of S.trifasciatavar.laurentii (variegated snake plant) on indoor environment. Methodology / Approach - An investigation in a house with two same bedrooms (experimental one and control one) was conducted during heating period in Jinan, Shandong, China. Indoor CO2 concentration, indoor air temperature and humidity, PM2.5 and PM10 concentration in two bedrooms were collected. Results –The results showed experimental room with three pots of S.trifasciatavar.laurentii was 1.6% higher in the room air relative humidity, 0.997℃ lower in temperature, 15.5% lower in PM2.5 concen-tration, 16.4% lower in PM10 concentration than the control room without plants. Also, each 1m2 leaf area of S.trifasciatavar.laurentii absorbed 2039.96mg CO2 per hour. For Chinese common housing, 15m2 bedroom needs about 4-5 pots of S.trifasciatavar.laurentii. Key Findings / Implications – The quantitative data in this study are very promising for future in-door environmental management. Originality - The possibility of reducing urban air pollution by lowering energy requirements of city buildings is also encouraging and nature's ability to cost-effectively mitigate urban pollution is impressive, and its development is urgently needed.
