Tap water in Europe is generally drinkable. But “drinkable” doesn’t always mean “pure”.
Although it meets health standards, it may contain traces of chlorine, heavy metals, microplastics, pesticides, or bacteria.
Filtering water at home is not a fad: it's a smart way to take care of your health, improve the taste of your water, and reduce unnecessary plastic consumption.
What you don't see in tap water
Chlorine: the necessary disinfectant... but not harmless
Chlorine is essential to ensure the potability of water in our homes. However, it also alters its taste and odor, and can react with organic matter to form unwanted byproducts that are harmful to our health.
Stefani's 3-stage filters guarantee a reduction of at least 96% of the chlorine present in the water , noticeably improving its taste and purity.
Heavy metals: a legacy of the pipes
Lead, mercury, or aluminum can leach from old pipes or enter the water through environmental contamination.
Even in small amounts, these metals can accumulate in the body over time and affect vital organs.
Stefani 3-stage filters retain approximately 99% of aluminum , 97% of lead and 96% of mercury , offering effective protection against these invisible contaminants.
Microplastics: the pollutant of the 21st century
Recent studies have detected microplastics even in tap water. These invisible particles come from the wear and tear of pipes, packaging, or synthetic fibers.
The long-term impact is still being studied, but we know they shouldn't be there .
Stefani's 3-stage filters effectively retain particles from 0.5 to 1 µm . 95 % of microplastics present in tap water are larger than 0.5 µm (source: ECHA – European Chemicals Agency ), which translates to an efficiency of nearly 95% in microplastic reduction .
Bacteria and microorganisms
Although the treatment system is effective, bacteria can reappear in the final stage of the water's journey, especially in rural areas or old buildings.
Thanks to the combination of their ceramic filtration and the antiseptic action of colloidal silver , Stefani filters are effective against 99% of potential bacteria and microorganisms , guaranteeing safe and fresh water at all times.
Benefits of filtering water at home
1️⃣ More purity, more trust
A good filtration system removes impurities that municipal treatment cannot, providing truly clean and safe water.
2️⃣ Better taste and smell
Removing chlorine and particles improves the taste of water and all the drinks you prepare with it: coffee, infusions or soups.
3️⃣ Zero waste, no plastics
Filtering water at home drastically reduces the consumption of plastic bottles and their environmental impact.
4️⃣ Long-term savings
In just a few months, the cost of a filter is recouped compared to the expense of bottled water.
Why choose a Stefani ceramic filter?
Not all filters are the same.
La Stéfani 's natural ceramic filters combine over 75 years of experience with a purification technology recognized in more than 45 countries .
Since 1947, we have perfected a simple, natural and scientifically effective method to provide the purest water possible .
Its three-stage filtration system achieves exceptional purity:
-
Microporous clay → retains microplastics, metals and bacteria.
-
Coconut shell activated carbon → removes chlorine, odors and tastes.
-
Colloidal silver → prevents the proliferation of microorganisms.
Furthermore, the system's effectiveness remains constant thanks to the periodic renewal of the filter every six months , a simple and affordable maintenance that ensures stable performance over time.
No electricity, no installation, and made with natural materials.
A solution proven by millions of homes around the world, where water purity and trust in science go hand in hand .
Conclusion: The water you choose reflects how you take care of yourself
Filtering tap water is an everyday gesture that changes much more than it seems.
Better taste, better health, less waste, and a feeling of peace of mind every time you fill your glass.
Because the purest water is not the one that looks clean, but the one that actually is.
