Comparison of NSF certifications and tests of the main gravity filters
Comparison of water filters: NSF certifications, laboratory tests and contaminants analyzed The NSF certification constitutes a real guarantee of seriousness. It means that a product, material or performance has been evaluated according to precise requirements by an independent organization. However, it does not mean that a filter automatically eliminates all contaminants present in the water. Each manufacturer chooses the performances, called claims, which he wishes to have tested or certified. Two filters carrying NSF certification can therefore have very different filtration capacities. To correctly compare several filters, you should not... Read more...
Why a new generation of water filters is emerging
Why a new generation of water filters is emerging After understanding the differences between granular coal and block carbon, a question naturally arises: why are these technologies evolving today? The answer is in one word: pollutants have changed. 1. Water different from yesterday For a long time, filtration systems have been designed primarily to improve: taste and odor (chlorine), suspended particles, certain traditional contaminants. Today, the reality is different. We are now talking about: pesticide residues, traces of medication, endocrine disruptors, complex organic compounds. These substances are often present in...

Activated carbon: granular or block, a difference that changes everything
Granular carbon or carbon block: what is the difference for filtering your water? When we are interested in water filtration by gravity, an essential technical point often remains unknown: the type of carbon used inside the filter. Two main approaches coexist today in gravity filtration systems: the combination ceramic + granular activated carbon, (used in many gravity filters on the market). the combination ceramic + carbon block. On paper, the two solutions are based on similar logic: combining a ceramic barrier to a carbon media intended to reduce many contaminants.... Read more...

Water alert in Nantes: sharp increase in hepatitis A cases
Atypical increase in hepatitis A in Nantes Since June 2025, 16 cases of hepatitis A have been confirmed in Nantes, a higher figure than in previous years. The ARS warns of this unusual upsurge. The virus is transmitted by the fecal-oral route: contaminated water or food, lack of hygiene. Water plays a key role, particularly in washing fruits and vegetables. In certain precarious homes, the absence of suitable toilets accentuates the risk. Symptoms include nausea, abdominal pain, fatigue and jaundice. Although generally mild, the infection can be serious in fragile... Read more...
Heatwave: watch out for this little-known risk linked to too much water consumption
During periods of extreme heat, we are often told: “Drink some water”. But it is also possible to drink it too much, to the point of endangering his health. This risk is called hyponatremia. What is hyponatremia? Hyponatremia is an abnormal drop in blood sodium (too much water compared to salt available, or we loses too much salt (sweating, certain medications) without compensating. The blood then becomes “diluted”, water enters the cells which swell (including in the brain), which can lead to serious complications. Symptoms to watch out for Nausea,... Read more...

The water looks clean… but is it really healthy?
Mirror Effect of Bacteria in Water: What You Need to Know Even after filtration, the water may contain fragments of dead bacteria : cell walls, toxins, DNA. These residues are no longer alive, but they can: cheat quality tests, stimulate immune reactions or allergies, alter taste or biological balance. 👉 This is called the bacterial mirror effect. : an illusion of purity. The awakening of dormant bacteria Some bacteria do not die: they go dormant in a state VBNC (Viable Purpose Not Cultivable). They survive: in the microcracks of used... Read more...

Water contamination with vinyl chloride
What is vinyl chloride? Vinyl chloride is a chemical compound used primarily in the production of PVC (polyvinyl chloride), a plastic widely used in pipes, packaging, coatings, etc. It is a colorless gas at room temperature, which can dissolve in water. Sources of water contamination: Industrial spills: Discharges from PVC manufacturing or processing plants. Leaks from storage sites or pipelines containing vinyl chloride. Groundwater pollution: Old industrial sites or landfills containing chemicals can release vinyl chloride into groundwater. Degradation of chlorinated solvents (such as tetrachlorethylene or trichlorethylene) can produce vinyl... Read more...
