Twin-Stage Undercounter Water Filter – KDF/GAC & Fluoride Removal
This dual-housing under-sink filter system combines two powerful filtration stages to deliver clean, great-tasting drinking water right at your tap — removing contaminants that standard carbon filters like Brita and PUR simply can't touch.
What It Removes
- ☠️ Chlorine, Lead, PFAS, PFOA & Heavy Metals — via KDF/GAC cartridge
- 🔵 Fluoride — via Activated Alumina cartridge
- ✅ 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): Uses Kinetic Degradation Fluxion (KDF), a high-purity copper-zinc formulation, to remove chlorine, lead, heavy metals, chemicals, VOCs, PFOA, PFAS, and more via redox (oxidation/reduction). Includes an integrated 1-micron absolute prefilter that captures cysts such as cryptosporidium and giardia.
- Stage 2 – Fluoride Removal Cartridge: Contains Activated Alumina media to remove 90%+ of fluoride from your drinking water. Unlike activated carbon filters, this stage specifically targets fluoride. Our KDF/GAC stage also removes any trace activated alumina that may carry over, delivering ultra-clean water.
Tested to NSF-53 protocol by an independent laboratory.

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 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).
Note: High pH/alkaline water will shorten fluoride filter life. Consumer is responsible for complying with all applicable state and local plumbing codes.
