These filters can remove impurities, bacteria, viruses, heavy metals, chlorine, and other harmful substances from water, thereby improving the quality and taste of the water.

[0003] Water filters are commonly used in domestic, commercial and industrial settings to ensure the quality of drinking and industrial water. In domestic use, water filters can be installed on the faucet or directly connected to the tap water pipe to provide clean drinking water. In commercial and industrial settings, water filters can be used to treat large amounts of industrial water, such as pharmaceuticals, food processing, beverage production, etc.
