Purcooflow 3-Stage Whole House Water Filter System, Heavy Metal Reduction, 20x4.5 Inch, Includes PP, KDF & CTO Carbon Block, 1" NPT Brass Ports, Drain Valves & Install Kit

Expert 3-Stage Heavy Metal Defense: Experience superior water purification. Stage 1 (PP Sediment) efficiently traps sand, rust, and dirt. Stage 2 features an advanced KDF media filter specifically designed to neutralize heavy metals like Lead, Mercury, and Arsenic. Stage 3 utilizes a premium coconut shell CTO carbon block to deeply adsorb residual chlorine, bad tastes, and odors.

Innovative Drain Valves for Easy Maintenance: Designed with user-friendly maintenance in mind, each of the three heavy-duty filter housings is equipped with a dedicated bottom drain valve. This feature allows you to quickly flush out accumulated sediment and depressurize the system before changing cartridges, making routine filter replacements entirely spill-free and hassle-free.

Durable 1" NPT Brass Ports: Built for reliable, leak-free performance, the system features reinforced 1-inch NPT solid brass inlet and outlet ports. This premium construction resists cross-threading, ensures a secure, tight connection to your main water line, and supports a consistent, high flow rate for your entire home.

Universal 20" x 4.5" Standard Fit: The system comes fully loaded with three heavy-duty 20x4.5 inch cartridges. The housing is designed to fit all standard-sized replacements, meaning you are never locked into proprietary filters and can easily and affordably source standard cartridges to keep your system running optimally.

Complete Installation Kit & Home Protection: This package includes everything for a smooth setup: a pre-assembled bracket, heavy-duty housing wrench, mounting screws, and Teflon tape. Go with the Pure Flow and upgrade your family's daily water supply with confidence.
