The clay filter is an efficient and traditional solution for purifying water, removing impurities, heavy metals and keeping the water fresh and safe.
The clay filter, a traditional icon present in Brazilian homes, continues to be one of the safest and most effective ways to guarantee pure and fresh water. Even amid the advancement of modern technologies, the clay filter stands out for its simplicity and efficiency. With a proven ability eliminating up to 95% of chlorine, pesticides, parasites and heavy metals such as iron, lead and aluminum, this water purification method is still widely used and recommended.
The surprising effectiveness of the clay filter
When it comes to water purification, the clay filter has a special place, especially because of its ability to remove a wide variety of impurities.
thanks to Candles ceramics that make up its filtration system, the filter is able to retain a large part of the contaminants present in the water.

Studies show that it removes 95% of lead and almost 100% of the cryptosporidiosis parasite, which can cause severe intestinal infections.
Another difference is how the clay filter keeps the water fresh.
Because it is made from porous ceramic, it can reduce the water temperature by up to 5°C, providing a pleasant sensation of freshness, especially on hotter days.
This additional benefit is one of the factors that explain why many consumers prefer clay filters, even when faced with more modern technological alternatives.
The tradition of clay filters in Brazil
The use of clay filters in Brazil dates back to the beginning of the 20th century.
It was around 1910 that the first models began to be manufactured, as a result of the influence of Italian and Portuguese immigrants who brought the technique to the country.
The production of the famous São João filter, made with red clay and a porous candle, began between 1926 and 1928, in the city of Jaboticabal, in the interior of São Paulo, by Cerâmica Lamparelli.
After the Second World War, in 1947, Cerâmica Lamparelli was acquired by the Stéfani family, who maintained the production of the filter with the same quality and technique.
Despite the adversities and the decrease in demand Over time, Cerâmica Stéfani has established itself as the largest producer of clay filters in Brazil and, possibly, in the world.
Although the market has faced challenges in recent decades, especially with the popularization of modern filtration systems, the clay filter is still widely used in several regions of the country.
Its efficiency, combined with low maintenance costs and reliability, ensures its presence in many homes, especially in areas where running water may not be 100% safe.
How does the clay filter filtration system work?
The secret to the efficiency of the clay filter lies in the simplicity of its mechanism. Filtration occurs naturally, by gravity.
The water slowly passes through the ceramic candles, where impurities are trapped, and then drips into the lower reservoir.
This slow process ensures that microorganisms and sediments are retained on the candles, resulting in clean, safe water for consumption.
Unlike others filtration systems, which use pressure to force water through, the clay filter allows for more effective purification.
Pressure-based systems, such as those installed directly on taps, can allow some contaminants to pass through due to the speed of the process, compromising water quality.
Necessary maintenance and care
For the clay filter to maintain its effectiveness, it is essential to follow some basic maintenance precautions.
Spark plugs, for example, must be changed periodically, as over time they accumulate dirt and impurities that can affect filtration.
The period for changing spark plugs varies depending on use, but it is recommended to replace them every six months or depending on the quality of the water in the region.
Another important point is cleaning the filter.
Many users make the mistake of using chemical products for cleaning, which can damage the ceramic and compromise the filtration capacity.
The recommendation is to wash the filter with water and a soft brush, without using soap or other products.
It is also essential to ensure that the water stored in the filter is always in a clean and contamination-free location.
This prevents the treated liquid from being exposed to new impurities, preserving its potability.
Clay filter: a sustainable and effective choice
Despite the numerous options available on the market, the clay filter remains a reliable choice for water purification.
Its ability to eliminate a wide range of contaminants, combined with its simplicity and cost-effectiveness, means that this method is still highly valued by many consumers.
Furthermore, its durability and low maintenance requirements are other attractions that reinforce its popularity.
In a scenario where water quality is a growing concern, the clay filter remains firm as an efficient, sustainable and affordable solution, providing safety and well-being for millions of Brazilians who opt for this traditional but proven effective alternative.
Scientific studies on this filter have been published in the book The Drinking Water Book, by Colin Ingram (June 2006). Ingram has 40 years of experience as a science writer, researcher, and technical publishing consultant. He has conducted extensive research programs on all aspects of drinking water and has evaluated and tested water purification products. He lives on the southern coast of Oregon, United States.

I know this efficiency and you have the best water to consume.
Without a doubt! The efficiency of the Brazilian clay filter is truly surprising. In addition to ensuring clean water, the fresh and natural flavor it provides is something that many other modern filters cannot offer. It is incredible how such a simple technology continues to be so effective for daily water consumption. Do you still use a clay filter in your home or have you tried other types of filtration?
indeed
I have two clay filters and I wouldn't trade them for high-tech ones.
Better to change the filter element right away
That's right, you've come to the best option! The clay filter is classic and efficient, providing quality water without relying on sophisticated technology. Many people who have tried modern filters end up going back to the traditional one because of the taste and the reliability of the filtering. And best of all: it's sustainable and economical! Is there anything in particular that you notice different about the water from the clay filter compared to high-tech filters?
THIS IS ALL A LIE. The only thing it really does is keep the water temperature pleasant. What really matters is the filter element that is placed in it. It can be of good or low quality. DISGRACEFUL
Perfect! I don't know how there are still ignorant people who believe this lie.
Ignorance is making comments without any basis or technical knowledge. From what I read, neither you nor Roberto Mothe Mothe and others even bothered to search the Inmetro website to find out what criteria are used to approve and “seal” these clay filters. Verification begins with the quality of the clay used as raw material in the manufacture of the filters.
Don't be embarrassed.
Do some research for the love of God before making **** comments like yours.
Worse is you and your innocence today in 2024, at the very least having done the L, go study a little more to learn about water contamination and effective means of purification
There you go, **** guys. LOL. Those who say what they want hear what they have to hear. These sites probably work or own these modern, crappy filters.
But it could also be true. As you yourself put it: it depends on the filter element: like a candle with activated carbon, in addition to the ceramic construction itself.
Truth.
I understand your frustration! The filter element really makes all the difference in the quality of the filtration, and it is crucial to ensure that it is of good quality. However, many studies indicate that clay filters, especially with good quality ceramic cartridges, have above-average performance, removing various impurities. The cool thing is that, in addition to the pleasant temperature, the filtration system itself can be quite effective when the right component is used. Have you tried any other filter that was more efficient for you?
ROBERTO, the information about retaining lead and iron already complicates the truth, since lead analysis is complicated, expensive and time-consuming. To retain iron, I only know of anionic resin and clay filters do not use this type of resin. Retaining lead is a fallacy, since this metal appears more in river water or in the post office. It is a good filter for retaining impurities in the water and keeping the water fresh. This filter does not even retain chlorine, but you can put one activated carbon candle and the other ceramic. I like this filter, but they are too expensive. Hugs, Armando acjexata@hotmail.com
Ruth is an intern? Or did she have nothing to write. OMG.
Mr Roberto, good morning.
It is fair and good form, before questioning the publication of the author of the text, to verify her education, which has a coherent writing style and is based on knowledge in the biological field.
And he even adds a swear word to finish it off 🤦🏻♀️‼️?
What is this?
In this case, you lose all reason and even insult and attack, in a rude way, a woman who was very well educated at a public university!
Now that is regrettable!
Fraternal hug,
TRUE.
PERFECT. THIS MAN'S ARROGANCE IS UNNECESSARY.
It's true. It's absurd.
Ms. Vera. I didn't identify your comment that someone made a disproportionate criticism, which I also didn't read. I would like to read your comment on this filter about retaining: Iron, Lead, Chlorine, and bacteria. It's a good filter, but it doesn't work miracles. Each item has its minimum and maximum limits in Ordinance 888/2021 of the MS.
It's true. It's absurd.
The filter is a ceramic material with a microporous wall that filters water by gravity, without adding chemicals, reducing impurities and retaining solid particles. What you are considering as a clay filter is just the container that receives the filtered water.
You're right! The "clay filter" is actually the container, while what actually filters the water is the ceramic candle with micropores that retain impurities. The advantage is that this filtration process occurs by gravity, without the addition of chemicals, ensuring clean and healthy water. The clay filter itself helps to keep the water at a more pleasant temperature, but the quality of the candle is what makes all the difference. Do you usually pay attention to the origin of the ceramic candles you use?
Ok, but your company is making a very serious comment about the quality of the CLAY FILTER. 100% to retain impurities or STD, but for METALS, they need to give more technical details, because they are talking about health and ANVISA needs to be notified to test this miracle.
