About This
- Dual Carbon 3-Stage Purification: Expertly configured for maximum water freshness. Stage 1 (PP Sediment) captures physical dirt, sand, and rust. Stage 2 (Granular Activated Carbon - GAC) rapidly adsorbs high volumes of chlorine and bad odors without dropping water pressure. Stage 3 (CTO Carbon Block) acts as a fine 5-micron polisher to deeply filter VOCs and lingering tastes, ensuring crystal-clear water.
- Innovative Drain Valves for Easy Maintenance: Designed with user-friendly maintenance in mind, each of the three heavy-duty housings features a dedicated bottom drain valve. This allows you to quickly flush out dirty water and depressurize the system before unscrewing the housing, making routine filter replacements completely spill-free and effortless.
- Durable 1" NPT Brass Ports: Built for reliable, leak-free long-term performance, the system is equipped with reinforced 1-inch NPT solid brass inlet and outlet ports. This premium metal construction prevents the cross-threading often seen in plastic ports, ensuring a secure connection to your main water line and supporting high-flow whole-house water delivery.
- Universal 20" x 4.5" Standard Fit: The system comes fully loaded with three heavy-duty 20x4.5 inch cartridges. The versatile housing design accommodates all standard-sized replacements on the market, meaning you are never locked into expensive proprietary filters and can easily maintain your system year-round.
- Complete Installation Kit Included: Get your home water upgrade running smoothly right out of the box. This comprehensive package includes a pre-assembled heavy-duty steel bracket, a specialized housing wrench, mounting screws, and Teflon tape. Go with the Pure Flow and enjoy a hassle-free setup that protects your appliances and enhances your family's daily water usage.
