Filtration de l'eau : que signifient réellement les certifications NSF
Why NSF certification is not a miracle indicator in water filtration
NSF certification is often seen as the gold standard in water filtration. However, it does not cover all contaminants and does not replace independent laboratory testing. Here's what she really... Read more...
Why NSF certification alone does not define the real efficiency of a water filter
The NSF logo is often presented as an absolute guarantee. However, two NSF certified filters can have very different performance. Here's how to really evaluate the effectiveness of a water filter. Read more...
Comparison of NSF certifications and tests of the main gravity filters
NSF: what the brands don't always explain to you In the world of water filtration, the mentions NSF 42, NSF 53 or NSF P231 are omnipresent. They inspire confidence, but they are also often misunderstood. The reality is simple: not all filters that mention “NSF” are NSF certified. A confusion frequent Many products say: “Tested according to NSF standards” But this does not mean: “NSF certified” The difference is important. NSF certified: an official validation A truly NSF certified filter has been the subject of official validation, with a precise... 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 carbon and carbon block, a question naturally arises: why are these technologies evolving today? The answer is in one word: pollutants have changed. 1. Water different from that of yesterday For a long time, filtration systems were designed mainly to improve: taste and odor (chlorine), suspended particles, certain classic contaminants. Today, the reality is different. We are now talking about: pesticide residues, traces of drugs, endocrine disruptors, complex organic compounds. These substances are often present... Read more...
Granular charcoal or carbon block: what is the difference for filtering your water?
Granular charcoal 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 major 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 a similar logic: combine a ceramic barrier with a carbon media intended to reduce many... Read more...
Perrier: more than 2,400 pallets still blocked after bacteriological deviations

Water alert in Nantes: sharp increase in cases of hepatitis A
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 resurgence. 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 some precarious homes, the lack of suitable toilets increases the risk. Symptoms include nausea, abdominal pain, fatigue and jaundice. Although generally mild, the infection can be serious in vulnerable... Read more...
Heatwave: be careful of this little-known risk linked to too much water consumption
During periods of extreme heat, we are often told: “Drink water”. But it is also possible to drink too much, to the point of endangering your health. This risk is called hyponatremia. What is hyponatremia? Hyponatremia is an abnormal drop in blood sodium (too much water in relation to the salt available, or when we lose too much salt (sweating, certain medications) without compensating. The blood then becomes “diluted”, the water enters the cells which swelling (including in the brain), which can cause serious complications. Symptoms to watch for Nausea,... 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. Water pollution groundwater: Old industrial sites or landfills containing chemicals may release vinyl chloride into groundwater. Degradation of chlorinated solvents (such as tetrachlorethylene or trichloroethylene) may produce... Read more...
