HydroLogic® BIGboy™ KDF85 Catalytic Carbon Filter Upgrade

HydroLogic BIGboy KDF85 Catalytic Carbon Filter Upgrade

Upgrade your HydroLogic BIGboy system's pre-filtration with this KDF85 Catalytic Carbon Filter. The more porous catalytic carbon media, combined with KDF85 alloy, captures a wider range of contaminants than standard coconut carbon, including water-soluble metals, chlorine, chloramines, iron, sulfur, scale, and heavy metals. Replace when the pressure differential between inlet and outlet exceeds 10%, or per your system's recommended service schedule.

Key Features & Benefits

• KDF85 + 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 BIGboy 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 BIGboy 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?

KDF85 media uses a copper-zinc alloy to electrochemically reduce chlorine, heavy metals, and sulfur -- contaminants standard carbon alone may not fully capture. The catalytic carbon component is more porous than coconut carbon, extending effective contact time.

When should I replace this filter?

Replace when the pressure differential between inlet and outlet exceeds 10%, or per your system's recommended service schedule. Track your system's usage or pressure readings so you catch the replacement point before performance drops off.

Do I need to replace the whole housing?

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

Does this filter address chloramine?

Yes -- the catalytic carbon media is effective against chloramine, unlike standard coconut carbon filters used in BIGboy systems, which often cannot fully remove it. This makes the KDF85 upgrade worthwhile for growers on municipal water treated with chloramine.
