Water filtration is a way of treating water to be fit for drinking, cooking, or whatever other use it may be put to. Water filters vary in kind: activated carbon filters, reverse osmosis systems, and sediment filters, all having different types that target contaminants such as chlorine, bacteria, heavy metals, and sediments. These are applied in residential, commercial, and industrial fields to improve the quality, make the taste better, and protect water from harmful agents. The fact that safe purified water is accessible makes water filters extremely important.
