Carbon Block Filter – Compatible with Culligan AC-30, AC-15 & LC-50 RO Systems

Designed to fit select Culligan reverse osmosis systems, including the AC-30, AC-15, and LC-50. Installed as Stage 2, it reduces chlorine, taste, odor, and other common contaminants before water reaches the RO membrane.

By removing chlorine at this stage, the carbon block filter helps protect the RO membrane from chemical damage and supports consistent system performance.
