Carbon CTO

About Our CTO Carbon Block Filtration Cartridges

Carbon block filtration products are known for their dense structure and consistent performance. Unlike loose granular carbon, a solid carbon block forces water through tightly packed media for better contact time. This design helps reduce chlorine taste and odor while supporting cleaner, clearer water at every tap. Our selection includes coconut shell carbon options, standard 2.5 x 10 cartridges, whole house sizes, and compatible replacements for popular systems. You can also choose multi-pack options for convenient scheduled changes throughout the year.
