The Express Water FLTWH2045CKP1 Whole House Replacement Filter Set is a 3-pack replacement filter set made for the Express Water WH300SCKP whole house water filtration system. The set includes Polyphosphate, Kinetic Degradation Fluxion (KDF), and Activated Carbon Block filters designed to filter incoming water throughout the home.

These replacement filters help reduce major water impurities including Heavy Metals, Scale, Chlorine, Chloramines, Rust, Dirt, Sand, Silt, VOCs, Industrial Agents, TOCs, Turbidity, Odors, and Cloudiness. The filters are designed for drinking, showering, cooking, and other household uses.

The KDF heavy metal filter combines catalytic carbon with high-purity ionically charged copper and zinc granules to reduce Heavy Metals, Iron, Lead, Nickel, Chromium and more. The Polyphosphate cartridge is designed to help protect against scale, corrosion, and sediment damage, while the carbon filter uses tightly packed carbon granules for high-capacity filtration.

The filter set provides filtration for up to 100,000 gallons or 6–12 months, depending on water quality, temperature, and incoming pressure. The filters are designed for high flow with almost no reduction in water pressure and can deliver up to 0.25 gallons of water per second.
