| Summary: | Pine trees were found to successfully filter water through their wood-xylem. This study focuses on filtering water using wood-xylem of tropical timber, i.e. Podo species. Samples from Podo branches were cut for 20 mm diameter with 40 mm length. The water was filtered with normal drip without pressure. The filtered water was tested for physical and chemical characteristics of water quality. The physical characteristics tested were colour and turbidity whilst the chemical char-acteristics were tested on dissolved oxygen demand, biochemical oxygen demand, chemical oxygen demand and pH value. The observations on the physical properties of Podo xylem were visualized using Dino-Lite Digital Microscope before and after the filtering process. After filtration, the suspended material from the water samples appeared as a dark spot at the inlet of the tracheid. It was clearly spotted from the cross-section view. From the water quality test, it shows that the characteristics of both physical and chemical characteristics of the filtered water were not improved and failed to comply with the characteristics as stipulated in Drinking Water Quality Standard respectively. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2023.
