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 versus 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. Well-water users and municipal-supply growers using chloramine disinfection benefit most.

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. Tracking pressure readings makes this easy to catch.

Do I need to replace the whole housing?

No -- this is a cartridge-only replacement. The existing filter 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. Choose whichever media best matches your current water chemistry and treatment goals.
