The study examined the physical and chemical characteristics of water and the effectiveness of coconut shell-activated carbon as a wastewater purifier. The physical characteristic of water as to its turbidity and odor was measured through a survey questionnaire checklist. Analysis of data revealed that the respondents agreed that after filtration, the water became clear and there was odorless proving that coconut shell-activated carbon can be an effective water purifier. Relatively, the laboratory test conducted on the sample of purified water to determine its chemical characteristics and revealed total dissolved solids, total suspended solid, pH at 25oC, and Chemical Oxygen Demand (COD) obtained a passed mark. Therefore, coconut shell-activated carbon infused in water can be a safe alternative to consume purified water.
