A filtering system to make water drinkable in poor countries. It is called the Berkey water filter and is capable of purifying the precious blue gold of harmful pathogenic bacteria, parasites or chemical contaminants at levels above 99,99%. For this he was chosen by Unicef, the International Red Cross, Save the Children and thousands of missionaries scattered in areas of the world where drinking water is not available.

A filter system for making water drinkable in poor countries or in the event of natural disasters. Is called Berkey water filter and is capable of purifying the precious blue gold of harmful pathogenic bacteria, parasites or chemical contaminants at levels above 99,99%. Because of this was chosen by Unicef, the International Red Cross, Save the Children and thousands of missionaries scattered in areas of the world where drinking water is not available.
Filters such as the Berkey water filter are useful against bacteria and protozoa, such as Cryptosporidium and Giardia lamblia, but one of the main advantages of Berkey filters is that it is enough to replace them only every 3-5 years, a very long time compared to other products on the market that must be changed within a few months. Replacing the filters less, in addition to being convenient from an environmental point of view, means really making the difference between life and death in a hypothetical emergency situation, such as in the case of natural disasters that involve the interruption of drinking water or the end of stocks.
Furthermore, they do not need electricity during use and are lightweight and portable. The Super Sterasyl filters used in Berkey products are an evolution of the technology of ceramic filters developed in 1827 by Henry Doulton, in Great Britain. The company he founded, the Doulton Company, continued to improve ceramic filters to create a product so effective that it was chosen by the military and humanitarian organizations.
Until today they are used in 140 countries where access to drinking water is limited. But their usefulness can also be extended in the event of natural disasters, such as floods or earthquakes, when blue gold is one of the first things to be lacking, thus allowing them to supply themselves from lakes, streams or ponds often polluted by harmful pathogenic bacteria, parasites or chemical contaminants. And, finally, they allow us to provide an opportunity to reflect on how much water is a precious commodity that we often take for granted.
