Abstract

This study investigates types of ornamental plants for improve indoor air quality by specifically reducing CO2 levels. The fourteen plant types examined are Epipremnum aureum, Spathiphyllum sp., Nephrolepis Exaltata, Chlorophytum Comosum, Codiaeum Variegatum Blume, Epipremnum Aureum (Linden & André) G. S. Bunting, Crinum asiaticum, Dracaena trifasciata, Diffenbachia picta Schott, Portulacaria afra f. variegata, Peperomia obtusifolia (L.) F.Dietr, Aglaonema cochinchinense, Pilea Cadierei, and Cordyline fruticose (L.) A.Chev. The ability of each ornamental plant to reduce CO2 levels was recorded over a 24-hour period. It was observed that Epipremnum aureum exhibited superior CO2 absorption capabilities compared to other ornamental plants in this study. It had an average CO2 absorption and release of -36 and 2 ppm, respectively, in the closed chamber, both during the daytime and nighttime. It is suggested to incorporate these plants in various living areas such as the living room, kitchen, bedroom, or office spaces.
