Activated charcoal, which is used in internal Seltino filter blocks is made from coconut shell. It is't most noble and the most effective filtering material.
The activated charcoal used in internal Seltino filter blocks is made from coconut shell. It is the most superior and effective filtering material.
Its effectiveness is achieved from its very high porosity and thus a very large wall surface.
100 grams of carbon has a wall surface of up to 10 hectares (100 thousand square meters). This surface is positively charged (activated) and attracts negatively charged bacteria, chlorine, dust particles and other germs.
Additionally, the highly compressed carbon block acts as a tight mechanical barrier which prevents even the smallest impurities passing into the refrigerator.
Sterile packaging and UV sterilisation in the production process help ensure the Seltino filters protect against bacteria without using silver nitrate; this way the water is free from silver compounds!
