What is a Ceramic Water Filter?

A ceramic water filter uses the tiny pores on a ceramic cartridge medium to filter out bacteria, dirt and sediment, cysts, turbidity and more. Ceramic filters are extremely affordable and can be installed into most benchtop water filters, and are commonly used in gravity fed benchtop water filters.

A benchtop water filter housing can also be ceramic, some may refer to it as a terracotta or pottery water filter, like the Filteroo Classic.


These ceramic water dispensers keep water cool throughout all seasons of the year. Even during those hot summer months, you can expect cool, refreshing water from a ceramic water filter dispenser.

How do Ceramic Water Filters work?

According to the CDC, ceramic filters have traditionally been used throughout the world to treat household water.

A ceramic water purifier combines mechanical filtration and physical adsorption processes to reduce a wide variety of drinking water contaminants of both aesthetic and health concerns.


The pore structure of a ceramic water filter candle enables sufficient contact time for the cartridge and the water to improve the taste and smell of the water, while also reducing contaminants such as chlorine, chloramines, pathogenic organisms, volatile organic compounds, herbicides and pesticides, heavy metals, and even fluoride.

All of this, of course, depends on the specific ceramic cartridge used because most ceramic cartridge manufacturers also include carbon on the inside of their cartridges.


A stone water filter purifies the water source by allowing it to pass through the millions of tiny pores of the ceramic medium. These pores can be as small as 0.5 microns and trap contaminants as they pass through.

Through this process, bacteria and sediment are eliminated from the water, and many other contaminants are significantly reduced.

The filtration process of a ceramic water filter cartridge is very similar to the way nature purifies water. In nature, water passes through layers of rock to streams, to rid itself of these contaminants.

A ceramic water candle is effective at removing harmful bacteria including E. Coli, cysts, sediment, lead and cryptosporidium.


Ceramic Water Filter Advantages

      • Highly effective removal of bacteria, dirt and sediment, cysts, turbidity and more.
      • Retains essential minerals in the water.
      • Made from 100% natural ingredients found on the earth.
      • Longlasting and affordable

Ceramic Water Filter Disadvantages

      • Not as effective at removing chlorine alone (that’s why most ceramic cartridges have carbon on the inside)
      • Breaks easily if dropped (so be careful when cleaning them)

Do Ceramic Water Filters Remove Fluoride?

Not all ceramic water filters remove fluoride. 

For treated city water, we highly recommend the Ultraceram fluoride removal cartridge as it removes fluoride up to 97%, and has super high removal rates for all the common contaminants such as chlorine & chloramine and other contaminants.

Feel free to check out the test results of the Ultraceram.
