Drinking water needs to be free from the heavy metals contained in them. Some of them include mercury, lead, and arsenic. The metals have a negative impact on the health of an individual. For instance, they affect a baby in the womb, they may cause coma and convulsions, they may lead to cancer and skin lesions, and they may affect the cognitive development of a child. For these reasons, there is the great need to make sure that there is the removal of the heavy metals from the drinking water. The method considered to be most cost effective here is filtration. This is the reason why there are several filtration systems that have been installed in people’s homes. It is affordable and also offers the results particularly if filters are chosen with several levels. Filtration functions by permitting only the minute particles to enter. This means that the ‘holes’ that are in the filter need to smaller as compared to the contaminants that are targeted for removal. By doing so, it means that all the pollutants will not have the opportunity to penetrate, and also, they will not find their way into the glass of water. When it comes to the options of filtration, the number of stages does not matter. The major concept of filtration is still maintained.
