iSpring WGB21B 2-Stage Whole House Water Filtration System – 1 Inlet/Outlet, 50,000 Gallons

Clean, reliable water for every tap

The iSpring WGB21B 2-Stage Whole House Water Filtration System brings a practical, whole-home filtration solution to your family. Designed for easy, do-it-yourself installation, this POE system sits at the main water line to deliver improved water quality at every faucet, shower, and appliance. The two-stage approach works to address common water quality concerns while preserving beneficial minerals in your water supply.

Two-stage filtration that addresses real-world needs

• Stage 1: Premium 5-micron polypropylene sediment filter (FP15B) captures dirt, sand, silt, rust, and scale particles, reducing visible cloudiness at the source.
• Stage 2: CTO carbon block filter (FC15B) minimizes chlorine taste and odor and is effective against VOCs, providing a fresher water profile for cooking and drinking.

With a replacement design that complements daily use, the system can deliver clean water to every outlet in homes of four, potentially lasting up to 50,000 gallons. The 1-inch inlet and outlet ports promote steady water flow with less pressure loss, helping protect plumbing and extend the life of connected appliances.
