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, public and private aquariums, and the safe use of ponds and swimming pools.

The Purifiers, also known as the Stryker Crusade, are a fictional paramilitary/terrorist organization appearing in American comic books published by Marvel Comics.

They are usually depicted as enemies of the X-Men.

Created by writer Chris Claremont and artist Brent Anderson, they first appeared in the 1982 graphic novel .

A mineral is a naturally occurring chemical compound, usually of crystalline form and not produced by life processes.

A mineral has one specific chemical composition, whereas a rock can be an aggregate of different minerals or mineraloids.

The study of minerals is called mineralogy.

Drinking water, also known as potable water, is water that is safe to drink or to use for food preparation.

The amount of drinking water required varies.

It depends on physical activity, age, health issues, and environmental conditions.

Americans, on average, drink one litre of water a day and 95% drink less than three litres per day.

For those who work in a hot climate, up to 16 litres a day may be required.

Water is essential for life.

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 biological, geological, 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.
