In France, 85% of us drink tap water, 85%, and to be sure of drinking good quality water, many have equipped themselves with a filter jug.
The enticing and reassuring promise of filter jugs has a lot to do with it: “Drinking healthier water than tap water and cheaper than bottled water”
However, it would seem that the filter jugs are not all good as we understand from reading the magazine Que Choisir of March 22, 2017 which titles: “Jugs, filters: useless, or even worse! “.
Indeed, the newspaper indicates “that a report from the National Health Security Agency (Anses) concludes that the effectiveness of filter jugs is more than questionable. »
What to choose writes: “ In its report, the Agency notes [… ]that the use of filter jugs can lead to the release of various contaminants (silver, sodium, potassium, ammonium ions) into the drinking water. Some filter jugs also cause a lowering of the pH of the water . »
We understand that this release can be problematic when reading Santé Magazine of August 30, 2020 in which we are told that the activated carbon filters used in certain filter jugs “are sometimes silvered in order to prevent the proliferation of bacteria on the filter . »
However, when these ion particles are released, “they could have an impact on the rhythm of the heart in certain patients suffering from heart failure. »
What to choose also explains in the article that these filter jugs can potentially become “real bacteria nests [… ]due to misuse of said decanters. Indeed, “the filter jugs keep their promise rather well in the laboratory, it is different when they are used at home. At home, bacteriological contamination is almost systematic and out of the 31 households having then lent themselves to experimenting with a carafe, all saw the quality of their water degraded by the filter carafe. »
You must therefore be very careful with filter jugs because they can provide you with poorer quality water if they are poorly maintained and they are not necessarily the best alternative to poor quality tap water.
