Ultima CTO Carbon Block Filter

Precision Carbon Block Filter for Superior Taste, Odor & Chlorine Removal

Enhance the final pre-treatment stage of your RO water purifier with the Ultima CTO Carbon Block Filter. Made from premium coconut shell activated carbon with a high iodine value of 900, this precision carbon block filter effectively removes remaining chlorine, unpleasant odors, and harmful organic impurities.

In addition to advanced chemical adsorption, the dense carbon block structure also provides fine particulate filtration, helping to trap residual sediment before water reaches the RO membrane. This dual-action performance improves water taste, protects the membrane, and ensures safer drinking water.

Available in universal 10-inch and 20-inch sizes, the Ultima CTO Filter is compatible with most standard RO water purifier systems.
