1 stick is enough to filter 1 liter of running water. However, the water quality is not equal in each municipality. We advise you to check the water quality of your city, village via this link https ://www.quechoisir.org/carte-interactive-qualite-eau-n21241/.(https://www.quechoisir.org/carte-interactive-qualite-eau-n21241/) If the water is of poor quality, prefer 2 sticks/L of water. Some sticks can filter 500ml or up to 2L of water depending on their size.

Vegetable charcoal, due to its high porosity, is weakened and can break by dropping a few particles. This phenomenon is completely normal for a natural product. Although broken, it will be all the more effective because its contact surface with water will become more extensive. The charcoal particles will help with digestion (just like powdered activated charcoal)!

You can completely leave it immersed in your container for 1 month and add water as needed (remember to let the stick act between 4 and 8 hours each time you fill it with water). After 1 month of continuous use, boil again for 10 minutes. then dry before placing it back in your decanter.

The vegetable charcoal is extremely porous because emptied of any substance accumulated during its life of wood. The activation phase thus makes it very light and it floats for the first few days of use to finally sink to the bottom of the container when its pores are full of water.

We have had the toxic adsorption capacities of the French activated carbon stick evaluated by an independent laboratory.Pre-water analysis(https://www.lecharbonactif.com/_files/ugd/bb4cc5_15d1b665dce740ea97855a41977933bf.pdf) Water analysis after(https://www.lecharbonactif.com/_files/ugd/bb4cc5_bb2ef7e5e543453a9b9afe514752e642.pdf)

Charcoal has the highest adsorption capacity of any known natural or synthetic material. It has the power to attract and retain toxic particles present in the air and in the water. It is therefore important (before use and every 1-2 months) to sterilize it by boiling it in order to free its pores of toxins.

Le charbon de bambou et celui de chêne ou hêtre offrent une efficacité similaire. Le bambou, issu d'une plante à croissance rapide, est une option écologique mais plus fragile. Le charbon de chêne ou hêtre, quant à lui, est plus robuste. Choisissez selon vos besoins et préférences !

Cela dépend de la qualité de l’eau de votre commune : • Recharge basique (charbon actif végétal) : Améliore le goût de l’eau et adsorbe les résidus chimiques à longues chaînes (chlore, pesticides, etc.). • Recharge PFAS + nitrates (charbon + résines échangeuses d’ions) : Recommandée si votre eau est contaminée par les PFAS ou les nitrates. Les résines agissent spécifiquement sur ces polluants, tout en améliorant le goût de l’eau grâce au charbon.
