2 Refill Cartridges for BottlePro lasting two months each (150L). Advanced 4-stage micro filtration technology that absorbs chemicals, gases, metals, organic elements and 80+ contaminants thanks to its microscopic structure and highly porous surface. Make sure to change refills on time.DirectionsIt is recommended to replace the cartridge every two months so as not to lose the effectiveness of the filtering. This is because:The refills are made of activated carbon, a material of organic origin that can be a breeding ground for microorganisms that over time can give rise to the proliferation of bacteria. These bacteria accumulate behind the filter and contaminate the water. In addition, the filtered lime will eventually reduce the water flow depending on the hardness of the source water.IngredientsCarbon fibre, BPA-free plastic, siliconeAllergen InformationVegetarian,Vegan,Certified Vegan,Kosher,Halal,Hypoallergenic
