In these recent years, the awareness among public about the good quality and clean water have been increased. Therefore, to ensure the water that will be consumed is clean, many people have installed water filter machine that filter the tap water at their premises before it being drank. As the awareness increasing, the manufacturer of various brand of water filter machine also increasing in terms of numbers and products. These companies are competing with each other to win people’s heart by offering variety of function of the water filter machine. The result from these water filter machine is either mineral water or reverse osmosis water. This study is carry out to determine the level of nutrients (Cu, Ca, Mg, Zn, F-, Cl and Ni ) and physical properties (pH, TDS and Turbidity) in filtered drinking water by various brand of water filter and compared with the drinking water standard from USEPA and the GDWQ by WHO. The results obtained from this research showed that the level of each element that have been analysed are within the guidelines except for turbidity and TDS. Therefore, the best drinking water can be obtained from water filter C as the there are many nutrients contents in water filter C are higher than other water filter and have physical parameters that still under the limitation of standard from both standards. The results obtained through this study is hoped to give baseline information to the public in order to choose which the best filter machine in the market. It is also hoped to give awareness to the public to have a good practices in maintaining the filter machine.
