Purigen is a premium synthetic absorbent that is unlike any other filtration product. It is not a mixture of ion exchangers or absorbents, but a unique macro-porous synthetic polymer that removes soluble and insoluble impurities from water at a rate and capacity that exceeds all others by over 500%. Purigen darkens progressively as it exhausts and is easily renewed by treating with bleach.
