Ceramic water filter is a cheap and effective type of water filter, which depends on the small pore size of the ceramic material to filter out dirt, grime, and bacteria out of the water.

Action methods
Like most filtration methods, water is carefully inserted into one side of the filter, which serves to block a larger portion of the pore size. Usually bacteria, protozoa, and microbial cysts are removed but filters are not effective against viruses because they are small enough to pass through the other "clean" filter side. Ceramic water filters (CWF) can be treated with silver in a form that will not fade. Silver helps to kill or paralyze the bacteria and prevent the growth of fungi and algae inside the body of the filter.
Ceramic filtration does not remove chemical contaminants per se. However, some manufacturers (especially ceramic wax filters) combine high-performance activated carbon cores in ceramic filter cartridges that reduce organic and metal contaminants. Activated carbon absorbs compounds such as chlorine. Filters with activated carbon need to be replaced periodically as carbon becomes blocked by foreign material.
The two most common types of ceramic water filters are the type of pot and wax type filters. The ceramic filter system consists of a porous ceramic filter attached, or placed on a plastic or ceramic container. Contaminated water is poured into the upper container. It passes the filter (s) into the container below. Bottom containers are usually equipped with a tap.
The larger contaminants from the small holes of the ceramic structure will remain at the top of the unit. The filter can be cleaned by brushing it with a soft brush and rinsing it with clean water. Hot water and soap can also be used.
In stationary use, ceramic wax has mechanical, operational and manufacturing advantages through simple inserts and pots. The filter wax allows powerful metal and plastic containers to be used, which reduces the possibility of sanitary failure. Since their filter area does not depend on the size of the attachment connection, leaks are less than other geometries of the replaceable filter, and more expensive and more expensive gaskets can be used. Because they are protected by top containers, rather than shaping them, they tend to be damaged in regular use. They are easier to clean, because the sanitary side is in the candle. The nonsanitary part is outside, where it is easy to clean. They better suit the type of container and application of simple pots, and stick to the simple holes in the container. They can also be replaced without replacing all of the top receivers, and larger containers can only use more filter wax, which allows the filter creation to be standardized. If the filter in the multifilter container is found to be damaged, the filter holes can be installed, and use may be continued with fewer filters and longer recharge time until replacement can be obtained. Also, standardizing the filters makes it economical to keep one or more filters in hand.
There are also portable ceramic filters, such as MSR Miniworks, which works through manual pumping, and in-line ceramic filters, which filter out drinking water coming through household pipes. Cleaning this filter is the same as clay pot filter but also allows cleaning of backflow, where clean water is forced through the filter to the back, pushing the contaminants out of the ceramic pores.
The main risks to the success of all forms of ceramic filtration are hair cracks and cross-contamination. If the unit is dropped or misused, its fragile ceramic properties may allow delicate cracks, hard to see, and may allow for greater contaminants through the filter. Work is underway to modify the ratio of clay/sawdust during manufacture to improve the brittle properties and fracture toughness of this clay ceramic filter material. Also, if the "clean" water side of the ceramic membrane is brought into contact with dirty water, hands, cleaning cloth, etc., then filtering will become ineffective. If the contact occurs, the clean side of the filter must be thoroughly sterilized before reuse.

Development and expansion
Henry Doulton invented the modern shape of a ceramic wax water sanitation filter in 1827. In 1835, Queen Victoria commissioned her to produce such a device for her personal use. In 1846, Doulton ceramics was widely recognized as a leading producer of effective prevention tools for treating infective water. In 1887, Doulton became a knight, partly because of his work with a water filter. Louis Pasteur's research on bacteria has also provided a provable reason for the filter effect. Doulton's original organization for water filters remains, though it has been sold and renamed several times. The current "Doulton" (2013) is a registered trademark of Fairey Ceramics.
Some universities include MIT; University of Colorado; University of Princeton; University of Wisconsin-Milwaukee; Ohio State University; University of Tulane, West Virginia, North Carolina in the US; University of Delft, Strathclyde in Europe, USAID, UNICEF, Zamorano University in Honduras, Rafeal Landivar University in Guatemala, Earth University, Institute of Hydraulic Resources, Red Cross, Engineers Without Borders, United Nations, African countries such as Nigeria, Ghana, Burkina Faso, Kenya, etc. And countries in Asia such as Nepal, Bangladesh, Cambodia, Sri Lanka, India, Vietnam, etc. And NGOs support the expansion of the use of ceramic filters in drinking water development initiatives; most often, in the form of clay pot filters.
Mr. Fernando Mazariegos of Guatemala was responsible for developing the Pot Ceramic Filter technology in 1981 while the Director of Water Research at the Central American Research Institute in Guatemala City. He is currently Director of Research and Development at Ecofiltro in Antigua, Guatemala. Ron Rivera studied under Mr. Mazariegos of Guatemala and is a major proponent and innovator in the field as part of a group to take pot-shaped pottery filters across international borders and help developing countries to provide cheap, high-quality drinking water. Ron Rivera is also working with Potters for Peace around the world for the benefit and benefits of clay workers in developing countries to keep their business
Recent developments are in India, NGOs such as Enactus IIT Madras, Rupayan Sansthan, Sehgal Foundation support the expansion and use of indu-shaped indu-native ceramic filter filters called G filters for water supply initiatives in Rajasthan.
