Terracotta water filters are natural water filters made of unglazed, porous clay that can remove impurities from water. These filters are commonly found in many parts of the world, including India and Bangladesh, and have been used for centuries.

Terracotta water filters are designed to work through a combination of physical and chemical processes. The porous nature of the clay allows water to seep through, while the fine particles and impurities are trapped within the tiny spaces between the clay particles. In addition, the high alkaline nature of the clay can help to neutralize the acidity of the water and remove some bacteria and viruses.

Terracotta water filters usually consist of two or three chambers, each filled with a different type of filtering material, such as sand, activated charcoal, or ceramic balls. The water is poured into the top chamber, where it gradually drips down through the filtering layers and into the bottom chamber, where it can be collected and consumed.

Drinking water from a terracotta water filter is believed to have health benefits, as the clay can help to alkalize the water and add trace minerals. In addition, terracotta water filters are a more sustainable and eco-friendly option for filtering water, as they are made from natural materials and do not contribute to environmental pollution like plastic water bottles.

Overall, terracotta water filters are a traditional and effective way to filter water naturally, and they are an important part of many cultural traditions around the world.
