A water filter removes impurities from water by means of 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, public and private aquaria, and the safe use of ponds and swimming pools.

Filtration is any of various mechanical, physical or biological operations that separate solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.

The fluid that passes through is called the filtrate.

In physical filters oversize solids in the fluid are retained and in biological filters particulates are trapped and ingested and metabolites are retained and removed.

However, the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size, filter thickness and biological activity).

Filtration occurs both in nature and in engineered systems; there are biologic, geologic, and industrial forms.

For example, in animals (including humans), renal filtration removes wastes from the blood, and in water treatment and sewage treatment, undesirable constituents are removed by absorption into a biological film grown on or in the filter medium, as in slow sand filtration.

Drinking water, also known as potable water or improved drinking water, is water that is safe to drink or to use for food preparation, without risk of health problems.

Globally, in 2015, 91% of people had access to water suitable for drinking.

Nearly 4.2 billion had access to tap water while another 2.4 billion had access to wells or public taps.

1.8 billion people still use an unsafe drinking water source which may be contaminated by feces.

This can result in infectious diarrhea such as cholera and typhoid among others.

Water purification is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from contaminated water.

The goal is to produce water fit for a specific purpose.

Most water is disinfected for human consumption (drinking water), but water purification may also be designed for a variety of other purposes, including fulfilling the requirements of medical, pharmacological, chemical and industrial applications.

The methods used include physical processes such as filtration, sedimentation, and distillation; biological processes such as slow sand filters or biologically active carbon; chemical processes such as flocculation and chlorination and the use of electromagnetic radiation such as ultraviolet light.
