Summary

• THE kaolin is a natural, very fine white clay, known for its microporosity.
• It constitutes the first mechanical barrier in our triple filtration cartridge.
• It retains sediments, fine particles and certain micro-organisms present in thetap water.
• A healthy, durable and natural material, kaolin does not alter the taste or odor of water.

A mineral material with unique properties

THE kaolin is a naturally occurring white clay, rich in silica and alumina. Used for centuries in ceramics and traditional medicine, it is now recognized for its exceptional filtration properties. Its microporous structure allows it to mechanically capture impurities present in thetap water : sand, rust, sediment and even certain bacteria.

It is not a processed product, nor a chemical additive: kaolin simply acts as a fine and stable physical barrier, allowing water to pass through while blocking unwanted intruders.

The role of kaolin in our triple action filter cartridge

In our system, the kaolin constitutes the outer layer of the cartridge. It is this which comes into direct contact with thetap water as it passes through the fountain. Its function is clear: to filter out the largest impurities from the start of the process.

Thanks to its specific granulometry, it slows down the water, channels it, and promotes the effectiveness of the following layers: the activated carbon, which absorbs chemical contaminants, and thecolloidal silver, which acts against germs.

Without kaolin, these two inner layers would become saturated too quickly. It therefore plays a vital role in the durability and overall effectiveness of the tap water filtration.

Natural, sustainable, tasteless and odorless

One of the great advantages of the kaolin is its neutrality. Unlike some filter materials, it does not release anything into the water. It does not alter taste, odor, or pH. It is a stable, ecological, and entirely natural medium.

Its thermal resistance and durability make it an excellent choice for gravity systems like ours, where water naturally flows through the filter layers.

Conclusion

Choosing a good filter also means choosing the right materials. kaolin is much more than just a component: it is the first line of defense against impurities in thetap water. Combined with the activated carbon and to thecolloidal silver, it forms a complete, natural solution, without added chemicals.

We offer you these Stefani filter cartridges, incorporating kaolin into all our filter fountainsA simple, effective and sustainable solution for filtering your water every day.
