This product is an exchange cylinder for an existing WH1MS system where the life of the media has become exhausted.
Standard (S) reduction filters are a general purpose filter which use Granular Activated Carbon media. They are effective at reducing chemicals (including herbicides and pesticides) and chlorine to improve water taste and odour.
Activated carbon filters remove/reduce many volatile organic chemicals (VOC), as well as benzene, trihalomethane (THM) compounds, radon, solvents and hundreds of other man-made chemicals found in tap water. They are not designed for and not generally effective at removing metals or sediment.
