These Pentek ChlorPlus Chloramine cartridges are rated for about 30,000 gallons each of city water that contains chloramine or chlorine. Chloramine is a 50/50 mixture of bleach and ammonia. This combination creates a poisonous gas that is designed to kill microorganisms in water. The gas is deadly if inhaled in high concentrations.
A special carbon is used to remove the chloramine from the water. This is the only carbon filter designed for the purpose of reducing the ammonia.
