"PurigenĀ® is a premium synthetic adsorbent that is unlike any other filtration product.
It is not a mixture of ion exchangers or low-capacity adsorbents, but a unique
macro-porous synthetic polymer that removes soluble and insoluble impurities
from water at a rate and capacity that exceeds all other competing products by over
500%. PurigenĀ® controls ammonia, nitrites and nitrates by removing nitrogenous
organic waste that would otherwise release these harmful compounds."
