Objective: to evaluate the efficiency of water treatment filters using activated carbon from different sources of biomass residue. Methods: this is a descriptive experimental study of a quantitative nature carried out at the Centro Universitário Católica de Quixadá, Ceará-Brazil, during the period from January to June 2018. Activated carbon filters were prepared, and subsequently, their efficiency in water treatment was evaluated. Wood waste, green coconut husk, cashew nut shell, and bamboo stem were used as a source of raw material. The water treatment filter was assembled using the column chromatography method by adding sand and cotton as other filter media. Physicochemical parameters were used to evaluate the efficiency of the built filters. Results: principal component analysis selected two water quality components, explaining 80.081% of the total variance. The cophenetic correlation coefficient of r=0.9572 indicates that the estimated dendrogram was good, considering the water quality parameters. Among the filters, bamboo showed the best response among the filters tested, being responsible for the reduction of several factors such as color, turbidity, total hardness, and sodium. Conclusion: activated carbon filters derived from discarded wood and cashew nut shells had little influence on improving water quality compared to the control sample
