For people with a substandard quality water supply, learning how to make a ceramic water filter is helpful. Households that have limited access to safe drinking water supplies are more likely to suffer from water-borne diseases, which are particularly damaging to young children.
Ceramic filtration is an effective water treatment option against these water transmittable diseases. But these filtration units are very costly to acquire. Hence, that is where a DIY ceramic water filter comes in.
You can make your own ceramic water filter system with four materials in six steps. Read on to find out!

What is a Ceramic Water Filter
Ceramic water filters are used by many countries throughout the world. The most widely used design is the flowerpot shape that sits in a plastic or ceramic receptacle. It usually has a diameter of 30 cm, a depth of 25 cm, and a capacity of six to ten liters. A lid is then placed on top to prevent contamination. It is the perfect setup to treat water and provide safe storage until you finish using the filter.
The DIY gravity water filter is ideal for point-of-use drinking water due to its effortless upkeep, 0.5-micron filtration ability, and low cost. It works great as a countertop or under-sink filtration. In addition, you can bring it during camping trips or hiking. When fitted with a proper cartridge, you can use it to make stream water drinkable.
There is a standard process in creating ceramic water filters. Before you get started, it is vital to have everything ready beforehand.
What You’ll Need
- Dry Clay
How to Make a Ceramic Water Filter
The recipe for a ceramic water filter and the standard process is based on what is recommended by the Potters for Peace organization, as follows:
1. Combine the dry materials
Put together the filtered dry clay and sawdust in a 50/50 ratio. Mix thoroughly.
2. Add water and continue mixing
Add water and blend until the mixture clump together.
3. Form into a filter shape
Wedge the clay thoroughly, forming it into a filter shape. Use molds and presses to assist.
4. Initial firing schedule
This process involves increasing the temperature to 75 degrees Celsius per hour until it reaches 350 degrees Celsius. It will allow the water moisture trapped in the clay to be absorbed without damaging the pots.
5. Up the temperature
Bring the temperature up to 900 degrees Celsius at a rate of 100 degrees Celsius per hour. Keep it at this temperature for an hour.
Remove the pot from the kiln and let it cool down naturally.
The exact ratio of the clay mixture, burnout material, and kiln schedule varies depending on several variables. The main goal here is to develop and create a filter with a greater rate of flow and maintain its effectiveness.
How Does a Ceramic Water Filter Work
A ceramic water filter works by filling the top receptacle with water flowing through the filter and into the storage. The ceramic filter has millions of half micron-sized pores that trap impurities as the water passes it.
In addition, the inside part of the filter features a complex maze of sharp angles meant to intercept any particles that have penetrated the exterior. With this design, one can say that the water percolation is excellent, particulate, and capable of removing host contaminants, including sediments and bacterias.
The purpose of this filtration system is to imitate the natural water purification process. We can compare it to the water seeping through the layers of rocks in the Earth’s surface and into the stream. The biological media is effective in getting rid of impurities and, thereby, resulting in clean water.
When to Clean and Replace a Ceramic Filter
The cleaning and maintenance of ceramic filters are easy. It is another benefit of this filtration system. Knowing the right time for maintenance is crucial to ensure that everyone enjoys quality filtered water.
After weeks of filtering water, the contaminants can build up on the exterior of the ceramic candle. It clogs the porous surface, which causes the water’s flow to slow down or stop. When this happens, you can take it as a signal to clean the ceramic filter.
While the filter can be cleaned and reused, there will come a time when a replacement is required. The ceramic might have a longer lifespan compared to its internal components. To maintain an efficient and quality water supply, you must not allow the filter to run past its rated gallon capacity if your unit has carbon media. Otherwise, you can continue with the regular clean-ups until the water stops flowing through.
A ceramic water filter is most appropriate in areas with poor water quality. It is a good substitute for costly filter systems due to its low one-time cost. However, it still effectively reduces contaminants like bacteria and protozoa in the water. Learning how to make one can be of great help for low-income families.
