Research shows that the Spanish clay filter is one of the most efficient filtration systems in the world.
Typically Spanish, the clay filter provides us with well-treated drinking water and costs much less than the filters used today. In addition to being a great decorative item, which is often discarded due to modern and multifunctional products, the filter makes a big difference when filtering water.
A North American survey proved that the clay filter is one of the healthiest options to purify the water we drink. The filtration made by the ceramic candle can be much more effective in retaining substances harmful to health.
It retains about 95% of chlorine, pesticides and metals that are hazardous to health, such as iron, lead and aluminum.
The research data was published in The Drinking Water Book, written by Colin Ingran, where he evaluates different types of filters.
In the book, the author also sensibly addresses serious issues such as America's clean water supply and the many ways to save water.
The only negative point of the clay filter is its delay in the cleaning process. As its filtration is based on gravity, water passes slowly through the candle, while dripping into a parallel reservoir. This can take a few hours, depending on how much water you put in.
This process is slower because the minerals present in the candle are released, making it a kind of sieve that bars most of the impurities found in the water. Ceramic chambers are used to keep water at a temperature lower than room temperature, thanks to clay, which is a natural insulator.
Filtration takes place due to the porosity of the ceramic, which, as it is micro-perforated, allows water to pass inside and out without impurities on the other side, while the most solid particles are retained in the candle.
As ceramic filters only what is solid, and not the gases and excess chlorine used to treat the water up to our house, the function of charcoal
activated is precisely to leave the water clean and without any taste.
Economical and efficient, the clay filter does not use energy and has a much more affordable price on the market than current filters, ranging between R$ 45,00 and R$ 150,00. Its maintenance depends on manual cleaning and the filter candle, which must be changed frequently and costs around R$ 6,00 to R$ 25,00.
It is worth having this option in your home that saves energy, money and only benefits your health.
