Filtered water is water that has been treated through a filtration process to remove impurities and contaminants such as bacteria, chemicals, chlorine, heavy metals (like lead and mercury), and other pollutants that may be harmful to human health. Filtration methods can vary and include physical filters like activated carbon, sand, and gravel, as well as chemical and microbial treatments. The goal of filtering water is to make it cleaner, safer, better tasting, and more pleasant to drink compared to unfiltered tap water. Unlike distilled water, filtered water generally retains beneficial minerals that are safe and good for health. Filtration systems can be simple manual setups or sophisticated home or industrial systems tailored to address specific water quality issues. Filtered water is commonly used for drinking, cooking, and cleaning. In summary, filtered water is cleaner, often better tasting water obtained by removing contaminants from tap or groundwater through various filtration techniques, while keeping beneficial minerals intact. The quality and effectiveness of filtered water depend greatly on the filtration system used. This type of water is widely preferred for daily consumption and is considered safer than unfiltered tap water.
