AF-20-2115-BB KDF-55-GAC Specialty Filter
Dual-action filtration combining coconut shell GAC with KDF-55 media for whole-house chlorine removal, heavy metal reduction, and bacterial inhibition
Redox media meets activated carbon for extended performance
KDF-55 Redox Process
Removes chlorine and reduces water-soluble heavy metals through oxidation-reduction, providing a chemical-free alternative for municipal water treatment
ResinTech Coconut GAC
Premium coconut shell granular activated carbon bonds contaminants at the molecular level, removing chemicals, tastes, and odors from your water supply
Bacteriostatic Protection
KDF media inhibits bacterial growth inside the filter cartridge, keeping your filtration system cleaner and extending the service life of the carbon bed
Extended Service Life
The combination of KDF-55 with activated carbon significantly extends cartridge life compared to carbon-only filters, reducing maintenance frequency and cost
