In order to remove any contaminants from the water, a water filter system might involves one or more filters. While some types of contaminants will be removed, but some will remain so that the water is not completely purify. Not all water filters extract the valuable minerals, but some will. It is fair to say that there are advantages and disadvantages to every filtration solution.
Carbon filters are often used for water purification, air filtering and processing of industrial gas. The activated carbon filter can reduce hundreds of substances in tap water, including contaminants and other chemicals. When the water flows through active carbon filters, the chemicals attach to the carbon which produces a purer water output. When filtering water, carbon filters are most effective in eliminating chlorine or chloramine and contaminants such as soil, volatile organic compounds, bad taste and odor. And, that is why is is very suitable filtration for drinking water.
Most people consider water filters are only good if you’re using them for your drinking water, but that’s not true. The most common method of water disinfection requires some sort of chlorine or its compounds, such as chloramine or chlorine dioxide. Chlorine is a powerful oxidant that destroys most harmful micro-organisms quickly. Natural water is an ideal environment for bacteria and viruses to grow Normally, chlorine in tap water kills both bacteria and viruses, which is why extraction of these substances is not necessary for public water or storage water.
According to EPA (Environmental Protection Agency in the United States), activated carbon is the only filter technology recommended to remove. https://www.epa.gov/remedytech/citizens-guide-activated-carbon-treatment
Activated carbon filter is an outstanding product and technology for water filtering and solves most, but not all issues. Make sure you understand the drawbacks of activated carbon and choose a filter based on your specific needs.
