The primary purpose of a water filter is to remove impurities and contaminants from drinking water. Filters can address a range of concerns, including sediment, chlorine, heavy metals, bacteria, and other pollutants that may be present in water sources. By utilizing various filtration methods, such as activated carbon, reverse osmosis, or UV treatment, water filters enhance the safety and quality of drinking water and improve its taste. Effective water filtration is essential for public health, especially in areas where water quality is compromised. It also can contribute to reducing plastic waste by providing an alternative to bottled water.
