Heavy Metal Reduction Testing

The CB-0.5 "Dual Media" Cartridge is designed for multi-purpose filtration of liquids. It contains a powdered activated carbon (PAC) briquette, which is more effective at reducing levels of VOC's and certain pesticides than granular activated carbon. In addition, the carbon briquette reduces levels of chlorine, sediment down to 0.5 micron, and Clardia and Cryptosporidium cystst.

The cartridge also contains a specially designed resin which reduces certain heavy metals such as lead, mercury, and cadmium. The design ensures that the water passes through three steps of filtration. In the first step, the polypropylene prefilter reduces coarse sediment particles. In the second, the PAC briquette absorbs chlorine, certain organic contaminants, and absorbable metals, as well as filtering particles down to 0.5 micron in size. A directional flow tube guides the water through the entire length of the resin bed, ensuring maximum contact. In the third and final step, the resin greatly reduces lead and certain other heavy metals that may be present in the water.
