A water filter removes impurities by lowering contamination of water using a fine physical barrier, a chemical process, or a biological process. Filters use sieving, adsorption, ion exchanges and other processes to remove unwanted substances from water.

Unlike a sieve or screen, a filter can potentially remove particles much smaller than the holes through which its water passes. They are made by multiple manufactures and are available in 0. 5-100 micron ratings as well as activated carbon. Some common substances that filtration does not remove are arsenic, bacteria, chlorides, fluoride, nitrates, perchlorates, pharmaceuticals, sodium and viruses. Water filters are used by hikers, aid organizations during humanitarian emergencies, and the military. These water filters should not be confused with devices or tablets that disinfect water which remove or kill viruses such as hepatitis A and rotavirus. NSF International as it is now known started out as the National Sanitation Foundation in 1944 at the University of Michigan School of Public Health.

The NSF’s water treatment Device Certification Program requires extensive product testing and unannounced audits of production facilities. National Science Foundation drinking water standards of contaminant reduction, aesthetic concerns, structural integrity, and materials safety. NSF standards for contaminant reduction performance, structural integrity, and materials safety. In the 1800s, mechanical filtration was an industrial process that depended on the addition of aluminium sulfate prior to the filtration process. The filtration rate for mechanical filtration was typically more than 60 times faster than slow sand filters, thus requiring significantly less land area. The first modern mechanical filtration plant in the U. Little Falls, New Jersey for the East Jersey Water Company.
