The reason why the tap water is not clean may be due to the secondary pollution of the water quality of the municipal water supply, and the current national standard water quality is far from meeting the drinking requirements. Therefore, for our quality of life, most household water needs some secondary treatment. The filter is a good choice, because the filter can use the adsorption principle of its activated carbon, quartz sand and other filter materials to effectively remove the color, odor and residual chlorine in the water.
