Purge cleans where you cannot! Purge contains SMARTZyme technology. SMARTZyme technology wastes no time breaking down non-living organic materials. A small amount of Natural Chemistry's enzymes can treat large amounts of water due to their ability to bind to non-living organic contaminants and reduce them to smaller and smaller parts, breaking them down to their original components such as carbon dioxide and water.
