No, your glass of tap water is not as pure as you think. From pesticide residues are still circulating, Despite controls and bans in France.
And the analyses carried out by Générations Futures and Data for Good confirm this worrying reality: in the North, West and the Paris agricultural basin, the concentration of these impurities in water regularly exceeds authorised thresholds.
The problem? These substances have an effect on our health, even in very small doses. As endocrine disrupters (such as bisphenol A [BPA]), they upset the hormonal balance. Some are carcinogenic, or suspected of being so, while others alter the nervous system, leading to cognitive problems and diseases such as Parkinson's.
In other words, even if the water remains «drinkable» on paper, daily exposure raises real health issues.
So how do you purify tap water effectively? Can conventional filter jugs do this?
Let's take a look at the best carafe filter against these chemical pollutants.
In France, pesticides and nitrates remain one of the most important main pollutants in tap water. And their intensive use has very real ecological and health consequences.
Under the effect of rain and irrigation, these products infiltrate the land, reaching the water tables and then the rivers, which are the main sources of our drinking water.
The result: these substances disrupt biodiversity, deplete soil quality and can ultimately affect human health.
And despite the progress made in water filtration and treatment, certain impurities persist. Compounds banned years ago, such as desphenyl chloridazone, are still detected in water distributed in France.
How is this possible? Because surveillance remains inadequate. According to the’UFC-Que Choisir, However, official analyses only look for a fraction of the existing molecules: around 200 out of more than 750 potentially present in the environment.
It's tempting to turn to bottled water for peace of mind. But we assure you: it's a bad idea! From studies have shown the presence of microplastics in many brands, as well as PFAS, those «eternal pollutants». Not to mention the high price, the inconvenient transport and the tonnes of plastic produced every year, only a tiny proportion of which is recycled.
Our verdict: no to the bottle!
So filtering your tap water is still the most effective option. But you still need to choose the right method.
Are filter carafes the best way?
Classic filter jugs, mostly made of plastic, such as the models from Brita, Philips, Aarke and Amazon, have won over many households. Practical, easy to use and space-saving.
The promise: pure, healthy filtered water that tastes even better.
Their operation is based on filters and cartridges composed of activated carbon and ion exchange resins, designed to retain chlorine, organic elements and some pesticides.
But on this last point, the results remain very limited.
ANSES confirmed this in its study on water treatment using filter carafes classics: «Questions remain about the effectiveness of eliminating contaminants such as nitrates, metals and pesticides from tap water. »
In other words, this filtration model is far from a success.
And that's not their only flaw:
ANSES and UFC-Que Choisir issue a warning The health risks: without maintenance, filters become veritable breeding grounds for bacteria.
Why do they do this? Because by removing the chlorine from the water, they also remove the natural barrier against microbes. It's almost inevitable!
Worse still, a carafe can release undesirable substances such as silver, sodium, ammonium and even plastic, which is present in some cartridges, while depleting the water of calcium and magnesium. The pH then becomes more acidic.
In addition catastrophic pollution generated by disposable filters (change every 3 to 5 weeks).
Paradoxically, the use of a carafe ends up altering the quality of the filtered water.
What if the real solution was a carafe without a filter, which was more efficient and long-lasting?
Not all filter carafes are created equal. Some simply improve the taste of the water, while others go much further by acting on the water's pH. invisible contaminants.
To help you make sense of the situation, here's a comparison of the main models and their purification capacity: a classic filter carafe, the LAVIE UV-A carafe, and the LAVIE UV-A carafe combined with the Opropre under-sink filter.

A filter carafe without a filter, that purifies water using light rather than a disposable cartridge? Yes, it's possible with the LAVIE UV-A carafe. Here's how it works.
Its patented technology is based on UV-A rays, which trigger a natural phenomenon known as chlorine photolysis.
In practical terms, when light shines through the glass bottle, the chlorine in the water is transformed into reactive radicals capable of neutralising pesticides, traces of medicines, bacteria and viruses. Fifteen minutes is all it takes to obtain pure, high-quality filtered water with no unpleasant taste.
But this product goes even further. Unlike conventional carafes, which require you to buy filters repeatedly, here there are no filters, no plastic and no pollution.
And it's even better for your health: no loss of essential minerals. Calcium and magnesium, essential for the body's balance, are fully preserved.
The scientific tests on its effectiveness are indisputable:
→ up to 49 % of chlordecone abatement,
→ more than 50 % reduction in glyphosate,
→ and 100 % of bacteria elimination.
Simple, durable, maintenance-free and filter-free, the LAVIE UV-A carafe provides gentle, healthy purification of tap water.
When you combine the LAVIE UV-A carafe with the Opropre Turquoise under-sink filter, you choose a complete and sustainable solution to purify tap water.
While the glass bottle and its light neutralise pesticides, drug residues and bacteria, Opropre acts upstream on PFAS, heavy metals (lead, mercury, arsenic, etc.), microplastics and nanoplastics.
Its secret: its ability to retain the most persistent substances of your water, thanks to a mixture of activated coconut carbon and specific resins.
And for the environment, no product is thrown away: cartridges are consigned, refilled and recycled, for quality water that tastes better and has zero waste impact.
Pesticides, particularly nitrates, are not the only contaminants to find their way into tap water. There are also PFAS, the «eternal pollutants» known for their extreme resistance, as well as heavy metals (such as lead, mercury and arsenic), microplastics and drug residues.
Carafes that require you to buy continuous filters (models from Brita, Philips, Amazon...) are ineffective against these invisible impurities.
On the other hand, the combination of the LAVIE UV-A carafe with the Opropre Turquoise under-sink filter is a very effective solution. a complete barrier thanks to activated coconut carbon and specific resins in the cartridge: the carafe neutralises organic molecules, while Opropre captures the finest particles such as PFAS, heavy metals and microplastics.
Together, they guarantee total water purification, without mineral loss or waste production.
