WIT :: T-Pure 3-Bank Replacement Cartridges

The WIT T-Pure 3-Bank Replacement Cartridges are a premium three-stage filter set engineered for the WIT 3-Bank T-Pure Pre-Filter System.
They provide complete protection for your water ionizer by removing fluoride, arsenic, chlorine, chloramines, heavy metals, and unpleasant tastes or odors, delivering clean, fresh-tasting water every day.

Stage 1 — 1 Micron Carbon Block

Removes sediment, chlorine, taste & odor

The first stage features a 1-micron carbon block that filters out visible particles, turbidity, and residual chlorine.
It improves taste, color, and odor while protecting the next filter stages from clogging.
This step ensures crystal-clear water flow and enhances overall filtration efficiency.

Stage 2 — Activated Alumina

Up to 95 % fluoride & arsenic reduction

Stage 2 uses 100 % Activated Alumina, a high-surface-area adsorbent that captures fluoride and arsenic ions.
Made from aluminum oxide (Al₂O₃), the same base mineral as rubies and sapphires, Activated Alumina provides deep molecular adsorption through micro-porous tunnels.
EPA recognizes this medium as an effective solution for fluoride, arsenic, uranium, sulfate, and selenate removal — achieving up to 95 % efficiency depending on pH and competing ions.

Stage 3 — KDF55 + Catalytic Carbon

Removes heavy metals, chloramines & odors

The final stage combines KDF55 (copper-zinc redox media) with Catalytic Activated Carbon for maximum chemical and metal reduction.
KDF55 neutralizes lead, mercury, nickel, and other heavy metals, while also suppressing bacterial growth and scale.
Catalytic Carbon removes iron, hydrogen sulfide, manganese, chloramines, and volatile organic compounds (VOCs) — leaving your water pure, odor-free, and naturally fresh.

Long Service Life & Easy Maintenance

Each T-Pure 3-Bank Replacement Cartridge Set delivers up to 12 months or ≈ 1,920 gallons (≈ 7,260 L) of service life under normal household use.
After replacement, always flush with 4 gallons of water before connecting to your ionizer to remove air and loose carbon fines.
No tools required — housings can be opened and tightened by hand.
