Twin-Stage Undercounter Water Filter – KDF/GAC & High Sediment Removal
This dual-housing under-sink filter system pairs the long-lasting KDF/GAC cartridge (12,000-gallon rating) with a full changeable 1-micron sediment pre-filter for extra contaminant removal and ultra-clean, cyst-free water. Recommended for areas with a high level of sediment or homes with old pipes, and for anyone wanting extra protection from cyst diseases.
What It Removes
☢️ Chlorine, Lead, PFAS, PFOA, Chemicals & Heavy Metals — via KDF/GAC cartridge
🪨 Sediment & cysts (Cryptosporidium, Giardia) — via 1-micron sediment pre-filter (1 micron is 1/25,000 of an inch; a human hair is about 100 microns)
✅ Leaves beneficial minerals intact — calcium and magnesium stay in your water
💧 Convenient — quality water right at your tap
How It Works
Stage 1 – KDF/GAC Cartridge (12,000-gallon capacity): Kinetic Degradation Fluxion (KDF) is a high-purity copper-zinc formulation that uses redox (oxidation/reduction) to remove chlorine, lead, chemicals, VOCs, PFOA, PFAS, and heavy metals. Tested to NSF-53 protocol by an independent laboratory.
Stage 2 – 1-Micron Sediment Pre-filter: A full changeable prefilter that captures sediment and cysts for ultra-clean water.

Installation
Quick-connect fittings make installation fast and tool-free. The system mounts out of sight under your sink, connects to the cold water line via an Angle Stop Valve, and dispenses through the included solid brass faucet. A ½" hole is needed for the faucet stud — a cover plate is included to fit larger pre-drilled holes (e.g., vegetable sprayer holes). Installation Instructions
