Ametek # 155403 Replaces Ametek CMR-10R. The CBR2 series are multimedia cartridges designed to perform several functions. CBR2 Series cartridges are manufactured using a patented process and combine powdered activated carbon with a specially designed media for lead reduction. In addition to lead reduction, the unique formation of the carbon block enables it to reduce Cryptosporidium and Giardia cysts and fine sediment particles down to 0.5 microns. As with our standard CBC Series carbon block, both the CBR2-10 and CBR2-10R are more effective at reducing levels of chlorine, and certain VOC's than granular activated carbon cartridges. The Polypropylene outer wrap helps reduce coarse sediment particles, effectively extending the useful life of the cartridge. Order a case and save even more. Learn More
