Vana AC - Active carbon filter - is an effective filter that absorbs impurities from the water.
Impurities such as chlorine, chloramine, herbicides, pesticides, solvents and dyes are absorbed by the activated carbon. The concentration of the impurities and the flow rate of the water have a direct impact on the life of the filter.
Activated carbon requires contact time with the water to be most effective.
Lower flow equals better filtration results, as the active carbon will have more time to adsorb the impurities.
