The study objective was to compare the interior greening volume ratios for the change in concentration of fine particle, temperature and relative humidity, and to identify the level of interior landscape volume ratio as a suitable condition to achieve the desired indoor properties. Plants were moved into a room (88m3) randomly. After moving, the volume ratio of the interior greening level was set at 0%, 1%, 2% and 3%. The concentration of fine particles was measured with a mini-volume portable air sampler (Air Metrics, USA). The temperature and relative humidity were recorded with a digital sensor (Kiwi-LTH, USA) during the experiment under different volume ratios with three replications. 1. The results of the change in concentration of the fine particles revealed a trend towards an increased volume ratio of interior greening with decreasing concentration of fine particles, compared to non-plants (0%). The concentration of fine particles at volume ratios of 0%, 1%, 2% and 3% was 55ug/$m^3$, 233ug/$m^3$, 40ug/$m^3$ and 30ug/$m^3$, respectively. 2. The change in temperature, at volume ratios of 0%, 1%, 2% and 3% was $21.2^{\circ}C$, $17.4^{\circ}C$, $16.7^{\circ}C$ and $18.9^{\circ}C$, respectively, in near interior greening, and $22.1^{\circ}C$, $18.7^{\circ}C$, $18.4^{\circ}C$ and $20.5^{\circ}C$ respectively, at a distance of 3m from the interior greening. These study results suggested that temperature was affected by volume ratio and distance from the interior greening. 3. The relative humidity, at volume ratios of 0%, 1%, 2% and 3% was 34.2%, 32.5%, 36.7%, and 46.9%, respectively, in near interior greening, and 31.2%, 26.9%, 31.4% and 38.3%, respectively, at a distance of 3m from the interior greening. With increasing volume ratio of interior landscape, there were positive and significant results between the distance difference and the relative humidity more than temperature.
