HydroLogic® PreEvolution™ KDF Catalytic Carbon Filter Upgrade

HydroLogic® PreEvolution™ KDF Catalytic Carbon Filter Upgrade

Upgrade your HydroLogic® PreEvolution™ system's pre-filtration with this KDF Catalytic Carbon Filter. The more porous catalytic carbon media — combined with KDF alloy — captures a wider range of contaminants than standard coconut carbon, including water-soluble metals, chlorine, chloramines, iron, sulfur, scale, and heavy metals.

Key Features & Benefits

• KDF + Catalytic Carbon Media — broader contaminant reduction than standard carbon, including chloramines and iron.
• More Porous Media — increases effective contact time and adsorption capacity vs. coconut carbon.
• Scale Reduction — helps protect RO membranes and downstream equipment from mineral buildup.
• For PreEvolution™ Systems — engineered as a drop-in upgrade over the standard green coconut carbon filter.

Who Should Use This

Growers dealing with high iron, sulfur, or chloramine levels in source water who want maximum pre-filtration before the RO stage. Ideal for well-water users or those on municipal supplies using chloramine disinfection.

Compatibility

Designed for HydroLogic® PreEvolution™ systems. Systems ship standard with Green Coconut Carbon filters — this is an upgrade replacement.

Frequently Asked Questions

What is the difference between KDF catalytic carbon and standard coconut carbon?

KDF media uses a copper-zinc alloy to electrochemically reduce chlorine, heavy metals, and sulfur — contaminants carbon alone may not fully capture. Catalytic carbon is more porous, extending effective contact time.

When should I replace this filter?

Replace when the pressure differential between inlet and outlet exceeds 10%, or per the recommended service schedule for your system.

Do I need to replace the whole housing?

No — this is a cartridge-only replacement. The housing remains in place.

Can I alternate between KDF and coconut carbon?

Yes — you can switch back to the standard Green Coconut Carbon filter at any service interval.
