The Brazilian Clay Water Filter is Considered The Best in the World

Cerâmica Stéfani, founded in 1947 by the De Stéfani brothers, is a Brazilian company - located in Jaboticabal, state of São Paulo - that initiated its activities with a manual production process of ceramic filters.

To this date, the majority of the pieces are handmade, allying the most modern production technologies for ceramic goods, which guarantees high quality products and very well rated in the national and international market.

Since the beginning of its activities, Cerâmica Stéfani dedicates to the production of water filters (by gravity and pressure) for household use and accessories for filters. Nowadays, with over 60 products in its portfolio, the company continues to innovate, in order to attend in a more efficient way, the needs of consumers.

São João was the first filter to be manufactured by Cerâmica Stéfani in 1947, maintaining its characteristics and tradition. After all those years in the market, it has marked its presence in at least three generations. All the sympathy that the public has for the São João filter is due to its unquestionable quality, durability and economy that comes along since birth.

According to research by US scientists, and published in the book “The Drinking Water Book: How to Eliminate Harmful Toxins from Your Water“ the traditional clay filter of Brazilians, is probably the best water purification system in the world.

Through its filter chamber, made of ceramic candles, it is able to remove impurities efficiently, in addition to containing the presence of chlorine, pesticides, iron, aluminum, lead and even a parasite that causes cryptosporidiosis.

This efficiency results from the gravity filtration process, where water passes through the candles and drips slowly into the lower reservoir. Exactly what does not happen in the flows of taps or tubing, since the pressure is who drives the flow of water. Therefore, microorganisms and sediments end up passing through the system and depositing in the cups. In addition, research has also shown that more modern filtration systems are not able to prevent the presence of dangerous elements such as fluorine and arsenic, for example.

However, remember that the quality of the water depends on the maintenance of the filter, which needs to be cleaned and have your candles changed regularly. And it is essential that chemicals or cleaners are not used in this process. In addition, care must be taken with the plumbing, taps and water tanks of the house, to ensure that the water placed there is suitable for consumption.
