HydroLogic® Evolution-RO™ ChloraShield® Carbon Filter Upgrade - 1 GPM - 1 Micron - Removes 100% Chloramine

100% Chloramine Removal for Evolution-RO City Water Users

The HydroLogic® ChloraShield® Replaceable Carbon Filter Upgrade is engineered specifically for city and municipal water users who need to eliminate chloramine — a disinfectant compound that standard carbon filters cannot fully remove. Rated at 1 GPM and filtering down to 1 micron, ChloraShield® removes 100% of chloramine and chlorine before they reach the RO membrane, protecting membrane integrity and maximizing product water purity.

Made in the USA with a low-pressure-drop design and high dirt-holding capacity, ChloraShield® is a direct drop-in upgrade over the standard Green Coconut Carbon Filter for growers whose municipal supply uses chloramine instead of, or alongside, chlorine.

Key Features & Benefits

• 100% chloramine removal: purpose-engineered for city water treated with chloramine, which standard coconut carbon filters often fail to fully address.
• Protects RO membranes: removing chlorine and chloramine before the membrane stage extends membrane service life and maintains TDS rejection performance.
• Made in the USA with a low-pressure-drop design that minimizes system pressure loss.
• High dirt-holding capacity: more porous than standard coconut carbon, supporting an extended service interval.
• 1-micron filtration for comprehensive pre-membrane water preparation.

Who Should Use This

Strongly recommended for Evolution-RO users on city or municipal water supplies where chloramine is used in place of — or alongside — chlorine. Standard Green Coconut Carbon Filters may not fully eliminate chloramine; ChloraShield is the purpose-built upgrade for this water chemistry.

Compatibility

Direct upgrade for: HydroLogic Evolution-RO systems, replacing the standard Green Coconut Carbon Filter — Replace every: 2,500 gallons — Dimensions: 17.125in x 2.75in.

Frequently Asked Questions

How is ChloraShield different from the standard carbon filter?

ChloraShield uses a more porous catalytic carbon media that is specifically effective against chloramine, a compound that standard coconut carbon filters are generally ineffective at removing. It also delivers a lower pressure drop and higher dirt-holding capacity.

How often should ChloraShield be replaced?

Replace every 2,500 gallons of water filtered to maintain consistent chloramine removal and membrane protection. Replacing on schedule also keeps pressure drop across the filter low.

How do I know if my water has chloramine?

Most municipalities publish water treatment reports online, and many city water systems use chloramine rather than or in addition to chlorine as a longer-lasting disinfectant. Contact your local water utility to confirm the disinfection chemistry used in your area.

Is this a direct drop-in replacement for my standard filter?

Yes — ChloraShield is a direct upgrade that replaces the standard Green Coconut Carbon Filter in HydroLogic Evolution-RO systems, with no additional modifications required. Installation follows the same steps as a routine carbon filter change.
