Water filter

A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters cleanse water to different extents, for purposes such as: providing agricultural irrigation, accessible drinking water, industrial use, public and private aquariums, and the safe use of ponds and swimming pools.
