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.
