What is the function of a water filter?

A water filter primarily serves the important function of removing impurities from water to ensure it is safe for consumption. Water can contain various contaminants, including sediments, chlorine, bacteria, and even heavy metals, depending on its source. The filtration process effectively reduces these undesirable substances, providing cleaner and safer water for drinking and cooking. This contributes significantly to health and well-being, as it helps prevent waterborne diseases and ensures that the water adheres to safety standards.

While adding minerals to water, like enhancing taste, may be a function of certain water systems, the fundamental role of a water filter is focused on purification rather than mineral enhancement. Increasing the temperature of water and reducing water pressure in the supply line are functions completely unrelated to filtration and do not address the primary concern of making water safe for human consumption.
